String handling routines in the C standard library

The standard C library, (which you can load into your program by including the statement #include <string.h> at the top of your program), contains many useful routines for manipulating these null-terminated strings.

I suggest you consult a reference source (or Wikipedia, e.g. C String Handling) for a list (it’s relatively long) of all the functions that exist for manipulating null-terminated strings in C. There are functions for copying strings, concatenating strings, getting the length of strings, comparing strings, etc.

An example: Concatenating two strings
