Please answer only in C++.

In this assignment you are to begin accumulating your own library of C-String functions. You can start with the instructions from 10.1 in the book for this chapter, but you will have to further refine your work. Create the four functions listed below. Each function must have a proper prototype and work correctly. In the main procedural area, provide a few lines of code to test each function. Each function must use C-Strings as arrays of characters. You are NOT allowed to use any existing C-string functions (that begin with str, like strcpy, strlen).
