live streaming of on the fly video effects and transformations through a dedicated JavaScript library for a maximum duration of one hour Ideal for device compatibility this protocol is perfect for embedding in web or mobile applications so that viewers can start streaming from any device on a web browser RTMP which can be initialized with an API call to Cloudinary returns an RTMP input URI for use with dedicated streaming software and hardware This protocol is ideal for delivering video content to viewers through multiple platforms IBM Cloud VideoPreviously known as Ustream IBM Cloud Video facilitates video and live streaming Pricing is on a subscription basis with Silver Gold and Platinum options You pay between to per month according to the hours viewed Usage might exceed the allotted number of viewer hours if an event runs longer than planned or becomes more popular than expected In that case additional fees might apply Large enterprises and institutions that hold townhalls or

海外TECH	DEV Community	C++ from the beginning - variables	https://dev.to/azure/c-from-the-beginning-variables-22nm	C from the beginning variablesTLDR This is the second part in a series about C In this part you learn about variables what they are what types exist and how you can use them to track state in your app  What s a variable and what to use it forWhen programming you write a set of instructions to be executed one after another from top to bottom Say you perform a calculation or you have some other piece of data that you want to save and refer to later at that point you need a variable A variable is a named reference holding a piece of data that remembers the data you assigned to it Here s an example int sum In this case you have the variable sum and it remembers the result of a computation of being added to Where you later to refer to this variable it s able to resolve into the value where you to print it for example like the below int sum statement statement statement statement cout lt lt sum prints In the above code you have just that scenario a computation on the first row several statements the program executes when run and finally you refer to sum again and it remembers its value Now that you see the idea of having a variable let s look at some concepts around variables that we need to know about Declare a variable it has a type and a nameYou ve seen a variable being created so far the variable sum but what did happen Let s look at it again int sum Above you are declaring a variable you tell the program a variable exists by a certain name sum and a type See the above as a combination of type and name lt type gt lt name gt int sum The type in this case is int and stores whole numbers like or and so on Initialise a variable type name and valueTo initialise a variable is similar to declaring a variable The difference is that when you initialise something you tell the program a variable exists by a certain name AND that it has a starter value for example int players  Different variable typesSo far you ve seen the type int storing whole numbers what other types are there Well let s list what we refer to as the basic data types in some programming languages referred to as primitivesint stores whole numbers for example or float and double stores numbers with decimals and decimals for float and decimals respectively for example char stores a single character like a or b here s an example a note the use of single quote bool stores true or false Here s an example canSave false Example with int and floatLet s look at an example of how our usage of float and int would differ int players float PI Above players makes sense to be a stored to be a whole number there s no part of a player For PI which is decimal with many many decimals a float is at least needed Even then it s an approximation You most likely need to make it a double and even then it doesn t hold enough decimals Operators like For number type variables operators plays a part in helping to perform calculations to add subtract multiply and so on Here s some operators you are likely to use adds two numbers together for example is removes right side from left side for example is divides left side right side times for example is multiplication multiplies the values with each other for example is modulo gives the left over when doing a division for example is  NamingNaming is important topic It s also a topic where folks don t usually agree on what to use There s one golden rule though be consistent use the same way of naming throughout To quote the creator of C BjarneName a variable function type whatever based on what it is or does Choose meaningful name that is choose names that will help people understand your program Bjarne on namingSome has suggestion Pascal casing for variables int account total and camel case for functions more on functions in future part in this series int calculateTotal SummaryIn this article you ve learned about some basic variables what they are why use them and some basic variable types You should now be better setup to use them to make your programs perform calculations and remember responses and making them easier to read	2021-11-03 22:07:26
