Calculate Characters in a String in C++ with Example


The string.h or cstring files must be included in programs that use standard functions to manipulate C strings. These header files grant access to the functionality of the C string library and are to be distinguished from the string header file that defines the string class. Each compiler offers additional header files for platform dependent functionalities. These may be graphics libraries or database interfaces.
