海外TECH	DEV Community	C Programming Cheat Sheet - 6	https://dev.to/codelyf/c-programming-cheat-sheet-6-26h9	C Programming Cheat Sheet Strings What is String Strings are arrays of characters Each member of array contains one of characters in the string Example include lt stdio h gt main char name printf Enter your name scanf s name printf Hello s how are you n name Output Results Enter your name Vineet Hello Vineet how are you If user enters Vineet then the first member of array will contain V second cell will contain i and so on C determines end of a string by a zero value character We call this character as NULL character and show it with character It s only one character and its value is however we show it with two characters to remember it is a character type not an integer Equally we can make that string by assigning character values to each member name B name r name i name a name n name As we saw in above example placeholder for string variables is s Also we will not use a amp sign for receiving string values Point to NoteWhile entering the string using scanf we must be cautious abouttwo things The length of the string should not exceed the dimension of the character array This is because the C compiler doesn t perform bounds checking on character arrays scanf is not capable of receiving multi word strings Therefore names such as Vineet Choudhary would be unacceptable The way to get around this limitation is by using the function gets The usage of functions gets and its counter part puts is shown below include lt stdio h gt main char name printf Enter your full name gets name puts Hello puts name And here is the output Enter your name Vineet Choudhary Hello Vineet ChoudharyThe program and the output are self explanatory except for the fact that puts can display only one string at a time hence the use of two puts in the program above Also on displaying a string unlike printf puts places the cursor on the next line Though gets is capable of receiving only one string at a time the plus point with gets is that it can receive a multi word string If we are prepared to take the trouble we can make scanf accept multi word strings by writing it in this manner char name printf Enter your full name scanf n s name Though workable this is the best of the ways to call a function you would agree Standard Library String FunctionsWith every C compiler a large set of useful string handling library functions are provided in string h file strlen Finds length of a string strlwr Converts a string to lowercase strupr Converts a string to uppercase strcat Appends one string at the end of another strncat Appends first n characters of a string at the end ofanother strcpy Copies a string into another strncpy Copies first n characters of one string into another strcmp Compares two strings strncmp Compares first n characters of two strings strcmpi Compares two strings without regard to case i denotesthat this function ignores case stricmp Compares two strings without regard to case identical tostrcmpi strnicmp Compares first n characters of two strings without regardto case strdup Duplicates a string strchr Finds first occurrence ofa given character in a string strrchr Finds last occurrence ofa given character in a string strstr Finds first occurrence of a given string in another string strset Sets all characters ofstring to a given character strnset Sets first n characters ofa string to a given character strrev Reverses stringMake sure to Follow me here to get the update when i post a blog	2021-04-11 14:09:56
