Write a program with three functions

Reference no: EM13700083

Question: Write a program with three functions: upper, lower, and reverse.

The upper function will accept a pointer to a string or C - string as an argument. It will step through each character in the string converting it(where necessary) to uppercase. The lower function will accept a pointer to a string or C - string as an argument. It will step through each character in the string converting it(where necessary) to lowercase.

Like the upper and lower functions, the reverse function will accept a pointer to a string or C - string. It will step through each character in the string converting uppercase characters to lowercase and lowercase characters to uppercase; numbers and special characters will be unaffected. The program will execute the functions in the following order : upper, lower, and reverse.

I have the answer already but i do not understand it; I need expert to guide through it step by step. thanks!
