These are defined in the string.h header file, which must be included in your source code when you use the functions, lest the compiler get cross with you. Two examples of string manipulation functions are: string length and string compare. The string length function has this format. Its single argument is a string variable or string literal. The function returns an integer, the number of characters in the string. This is a size_t data type, an integer that represents bites of storage in memory.
