海外TECH	DEV Community	What is Semantic HTML and Why Should We Care?	https://dev.to/ohdylan/what-is-semantic-html-and-why-should-we-care-4h59	What is Semantic HTML and Why Should We Care HTML tags tell the browser how to structure and display the content for the web pages Semantic HTML is a feature which we can write HTML codes in a more descriptive way It makes people understanding the role of this line or chunk of codes instead of how they should structure or look like Before semantic HTML we often see a bunch of div tags p tags span tags which tells nothing about their content and we normally use an id to tell what they are for or commenting However we can do this in a more self explanatory way without putting id or classes just to describe what their roles are Here are codes before semantic HTML lt div id header gt lt div id nav bar gt lt a href index html gt Home lt a gt lt a href about html gt About Us lt a gt lt div gt lt div gt lt div id main gt This is the section where main content goes lt div class content gt lt div gt This is for section content lt div gt lt div gt lt div class content gt lt div gt This is for section content lt div gt lt div gt lt div class content gt lt div gt This is for section content lt div gt lt div gt lt div gt lt div id footer gt lt div gt This is for footer lt div gt lt div gt This is with the utilization of semantic HTML lt header gt lt nav gt lt a href index html gt Home lt a gt lt a href about html gt About Us lt a gt lt nav gt lt header gt lt main gt This is the section where main content goes lt section gt lt h gt Section lt h gt lt div gt This is for section content lt div gt lt section gt lt section gt lt h gt Section lt h gt lt div gt This is for section content lt div gt lt article gt lt figure gt lt img src whatever png gt lt figcaption gt This is the image caption lt figcaption gt lt figure gt lt p gt Article content goes here lt p gt lt article gt lt section gt lt section gt lt h gt Section lt h gt lt div gt This is for section content lt div gt lt section gt lt main gt lt footer gt lt div gt This is for footer lt div gt lt footer gt These are some examples of semantic HTML introduced in HTML that you can use in your codes lt header gt Containing introductory items for the webpage and navigation menu It is similar but different from lt h gt as lt header gt is used to represent the section and lt h gt is used to put the title for that section lt footer gt Containing the footer information for example copyrights privacy policy contacts etc lt nav gt Containing navigation links lt main gt Represents the main content area this should only be used once in the pageA document must not have more than one main element that does not have the hidden attribute specified lt section gt Represents a standalone generic section each section should ideally have a header for that section itself lt figure gt amp lt figcaption gt This self contained element can be used to group image with its captionAnd there are around of them Here are some of the benefits of using semantic HTML Readability lt header gt lt footer gt lt nav gt they act mostly like a lt div gt however this will give a clearer understanding of what are the contents inside these blocks From the two code blocks above I feel that the second block is easier to read and understand As a developer we often need to look at other people s codes Therefore semantic HTML would definitely improve the reading experience of your codes Improve SEOThese keywords will improve the search ranking of your content because it provides richer information instead of lt div gt which tells nothing to the search engines AccessibilitySemantic HTML will improve the accesbility of your web page which gives clear context to audiences who access these pages through a screen reader or relying on keyboard only navigation using tab key to jump from section to section For example you might want to use lt button gt instead of just solely the lt a gt tag for a button For additional information you may also assign role attribute to lt a gt with the value of button This will also be recognized by screen reader I hope this gives you an insight of what semantic HTML is and how this could improve our code quality Cheers Do follow me for more future articles on web design programming and self improvement	2021-12-12 10:26:37
海外TECH	DEV Community	Part 2: Operators, User input, and if/else statements	https://dev.to/iayeshasahar/c-explain-like-im-five-part-2-operators-user-input-and-ifelse-statements-gik	Part Operators User input and if else statementsHi folks this is the second part of my series “C Explain like I m five In this part I will be explaining operators user input and if else statements in detail So fasten your seat belts and let s get started Operators in C An operator represents an action For example “ is an operator that represents subtraction just like “ is an operator that represents multiplication It works on two or more operands and produces an output For example here the “ operator works on three operands and produces as output Types of Operators in C There are main types of operators used in C which are •Basic Arithmetic Operators•Assignment Operators•Auto increment and Auto decrement Operators•Logical Operators•Comparison relational operatorsNow let s take a look at these operators in detail Basic Arithmetic OperatorsBasic arithmetic operators are • is for addition• is for subtraction• is for multiplication• is for division• is for modulus This operator return remainder would return Examples of Arithmetic operators are include lt iostream gt using namespace std int main int numA int numB cout lt lt numA numB lt lt numA numB lt lt endl cout lt lt numA numB lt lt numA numB lt lt endl cout lt lt numA numB lt lt numA numB lt lt endl cout lt lt numA numB lt lt numA numB lt lt endl cout lt lt numA numB lt lt numA numB lt lt endl return Output numA numB numA numB numA numB numA numB numA numB Assignment OperatorsIn C assignments operators are numB numA would assign value of variable numA to the variable numB numA is equal to numB numB numAnumB numA is equal to numB numB numAnumB numA is equal to numB numB numAnumB numA is equal to numB numB numAnumB numA is equal to numB numB numAExample of Assignment Operators include lt iostream gt using namespace std int main int numA int numB numB numA cout lt lt numB numA lt lt numB lt lt endl numB numA cout lt lt numB numA lt lt numB lt lt endl numB numA cout lt lt numB numA lt lt numB lt lt endl numB numA cout lt lt numB numA lt lt numB lt lt endl numB numA cout lt lt numB numA lt lt numB lt lt endl numB numA cout lt lt numB numA lt lt numB lt lt endl return Output numB numA numB numA numB numA numB numA numB numA numB numA Auto increment and Auto decrement Operators and are auto increment and auto decrement operators num equals num num num equals num num Example of Auto increment and Auto decrement Operators include lt iostream gt using namespace std int main int numA int numB numA numB cout lt lt numA is lt lt numA lt lt endl cout lt lt numB is lt lt numB return Output numA is numB is Logical OperatorsLogical Operators are operators that are used with binary variables They are mainly used in conditional statements and loops for evaluating any certain condition Logical operators in C are amp amp and Let s say we have two boolean variables a and a a amp amp a will return true if both a and a are true else it would return false a a will return false if both a and a are false else it would return true a would return the opposite of a which means that the output would be true if a is false and it would return false if a is true Example of Logical Operators include lt iostream gt using namespace std int main bool a true bool a false cout lt lt a amp amp a lt lt a amp amp a lt lt endl cout lt lt a b lt lt a a lt lt endl cout lt lt a amp amp a lt lt a amp amp a return Output a amp amp a a a a amp amp a Relational operatorsThere are six relational operators in C gt lt gt lt • returns true if both the left side and right side are equal• returns true if the left side is not equal to the right side of the operator• gt returns true if the left side is greater than the right• lt returns true if the left side is less than the right side• gt returns true if the left side is greater than or equal to the right side• lt returns true if the left side is less than or equal to the right sideExample of Relational operators include lt iostream gt using namespace std int main int numA int numB if numA numB cout lt lt numA and numB are equal lt lt endl else cout lt lt numA and numB are not equal lt lt endl if numA numB cout lt lt numA and numB are not equal lt lt endl else cout lt lt numA and numB are equal lt lt endl if numA gt numB cout lt lt numA is greater than numB lt lt endl else cout lt lt numA is not greater than numB lt lt endl if numA gt numB cout lt lt numA is greater than or equal to numB lt lt endl else cout lt lt numA is less than numB lt lt endl if numA lt numB cout lt lt numA is less than numB lt lt endl else cout lt lt numA is not less than numB lt lt endl if numA lt numB cout lt lt numA is less than or equal to numB lt lt endl else cout lt lt numA is greater than numB lt lt endl return Output numA and numB are not equalnumA and numB are not equalnumA is greater than numBnumA is greater than or equal to numBnumA is not less than numBnumA is greater than numBBefore moving on to other topics let s discuss how to take user input in C User InputAs you all already know by now that cout is used to output print values Here we will use use cin to get user input It is a predefined variable that reads data entered from the keyboard with the help of the extraction operator gt gt Example Here the user can input a number which is then stored in the variable a Then we will print the value of a include lt iostream gt using namespace std int main int a cout lt lt Type any integer cin gt gt a Getting user input from the keyboard cout lt lt The entered integer is lt lt a return Output Type any integer The entered integer is Since we have now covered all the introductory topics let s move on to Flow Control if else statements switch statements loops etc The first topic we will cover is if else statements if else statementsIn if else statements we can use all the relational operators discussed above to perform different actions for different tasks For a deeper understanding take a look at the example of relational operators again The conditional statements in C are if It is used to specify a block of code to be executed if a specified condition is true else It is used to specify a block of code to be executed if the same condition is false else if It is used to specify a new condition to test if the first condition is false switch It is used to specify many alternative blocks of code to be executed We will discuss switch statements in detail later if statementThe if statement is used to specify a block of C code to be executed if a condition is true Syntax if condition block of code to be executed if the condition is true Example Program to print only positive integers entered by the user include lt iostream gt using namespace std int main int num cout lt lt Enter any integer cin gt gt num to check if the entered number is positive if num gt cout lt lt You entered a positive integer lt lt num lt lt endl cout lt lt This statement is always executed return Output Enter any integer You entered a positive integer This statement is always executed Nested if statementWhen there is an if statement inside another if statement the resultant structure is called the nested if statement Syntax if condition A Statement s if condition B Statement s Example include lt iostream gt using namespace std int main int a This is a nested if statement as there is an if statement inside another if body if a lt cout lt lt Number is less than lt lt endl if a gt cout lt lt Number is greater than return Output Number is less than Number is greater than else statementThe else statement is used to specify a block of code to be executed if the condition is false Syntax if condition This block of code will be executed if the condition is true else This block of code will be executed if the condition is false Example include lt iostream gt using namespace std int main int age if age lt cout lt lt Underage else cout lt lt Adult return Output AdultIn the example above age is greater than so the condition is false Because of this we then moved on to the else condition and printed to the screen Adult If the age was less than the program would print Underage Nested if else statementJust like in nested if statement here too we add another if statement inside an if statement body But we can also add else and else if according to our necessity inside the second if statement Moreover we can nest multiple layers of if statements This may seem complex but it is really easy In order to understand this let s take a look at the example Example This is a program to find if an integer is even or odd or neither using nested if statements include lt iostream gt using namespace std int main int a cout lt lt Enter any integer cin gt gt a Main if condition if a inner if condition if a cout lt lt The number is even lt lt endl inner else condition else cout lt lt The number is odd lt lt endl Main else condition else cout lt lt The number is and it is neither even nor odd lt lt endl cout lt lt This statement is always executed lt lt endl Output Enter any integer The number is even This statement is always executed else if statementThe else if statement is used to specify a new condition if the first condition is false It is used to check multiple conditions Syntax if condition A if condition A is true then execute this statement s else if condition B execute this if condition A is not met and condition B is met statement s else if condition C execute this if condition A amp condition B are not met and condition C is met statement s else if none of the above mentioned conditions are true then these statements will get executed statement s Example include lt iostream gt using namespace std int main int num cout lt lt Enter an integer number between amp cin gt gt a if num lt amp amp a gt cout lt lt Its a two digit number else if a lt amp amp a gt cout lt lt Its a three digit number else if a lt amp amp a gt cout lt lt Its a four digit number else if a lt amp amp a gt cout lt lt Its a five digit number else cout lt lt number is not between amp return Output Enter an integer number between amp Its a four digit numberThat s all for today All those who haven t read the first part of the series can do so from here In the next blog I will be explaining some other parts of flow control so stay tuned Let s connect Twitter Github	2021-12-12 10:26:16
海外TECH	DEV Community	React Native VS Flutter - What's Best for You?	https://dev.to/surajondev/react-native-vs-flutter-whats-best-for-you-4p7f	React Native VS Flutter What x s Best for You IntroductionMobile App development is booming from the last decades and there is no stopping in it I tried to learn Mobile App development many times in the past but didn t succeed Problems I faced while learning it Language I am a web developer so I know JavaScript well But for the android app you need to know either Java or Kotlin I know Java but not that much Same in iOS you need to learn Swift Android Studio I felt Android Studio is more complicated Hard to Understand Recently once again I decided to learn mobile app development but with a twist I was not going to use a native development platform but with a cross development platform for both Android and iOS After so much research and reading articles there are two main cross platform frameworks for developing a mobile application One is React Native and the other is Flutter Today we are going to dissect both of them to know which suits you best So let s get started What is Cross Mobile App Development Let s first clear the Cross mobile app development question The term Cross Mobile App Development implies that the developer can run their program on the various mobile platform in our case Android and iOS simultaneously with a single code base You do not need to write separate code for a separate platform This saves time and costs to hire two sets of developers for the same application So now move to the introduction of our two frameworks React NativeReact native is an Open Source cross platform mobile app development framework developed by Facebook in It can be used to develop an application for Android Android TV iOS macOS TVs Web Windows and UWP by enabling developers to use React s framework along with native platform capabilities WikipediaReact Native uses JavaScript which makes it simple for web developers to develop mobile applications If you are familiar with React framework The Concept for React Native is almost similar to React All these factors led to more popularity of React Native in the community Application developed using React NativeFacebookInstagramUberEATSPinterestDiscordSkypeAnd Many More FlutterFlutter is an open source UI software development kit created by Google It is used to develop cross platform applications for Android iOS Linux Mac Windows Google Fuchsia and the web from a single codebase First described in Flutter was released in May WikipediaThe biggest competitor for React Native is Flutter Recently flutter is gaining a lot of popularity Google Trends shows more searches for Flutter than React Native in recent times Flutter uses the Dart programming language It is developed by Google Application developed using FlutterGoogle PlayStoreeBayTencentsDreamByteDanceGoogle AdsAnd Many More Difference betweenLet s find out which framework is more superior in the following conceptConceptDescriptionWinnerPerformanceJS is faster than Dart But Flutter is way faster on Android and iOS than React Native FlutterDesignReact Native has Native look for both Android and iOS by default Flutter uses the custom widget React NativeCommunityReact Native has a bigger community than flutter but the flutter community is growing at a faster pace React NativeBuild amp Release Automation SupportFlutter has development support through CLI and deployment with Fastlane which is missing in React Native FlutterThird Party LibrariesReact Native supports many libraries it supports most of the React based libraries too Flutter has few third party libraries React NativeTestingIn flutter you can perform unit testing integration testing and widget testing In React Native you depend on third party tools FlutterNumber of Appsmore than K apps are built using React Native and only more than K using Flutter Also top apps use React Native than flutterReact Native Learning Path FlutterFlutter uses Dart Dart is developed by google which is an Object Oriented Programming Language For an absolute beginner learning Dart and then Flutter will be easier Dart gt FlutterSo for a beginner who wants to learn cross mobile app development framework Flutter will be ideal React NativeReact Native s learning path consists of learning JavaScript as the primary programming language having knowledge of React and then you can learn React Native JavaScript gt React gt React NativeTo learn React Native you should know JavaScript and React This makes it a little longer learning path as compared to flutter for a beginner ConclusionBoth frameworks are capable of building beautiful and useable apps for both Android and iOS You can choose what s the best fit for your requirement I choose React Native for its learning path As I know React and JavaScript React Native is easier to learn So I will upload lots of content regarding React Native in the upcoming days Make sure to follow me for that content Thanks for reading the blog post	2021-12-12 10:25:31
