Please use code tags when posting code. That involves putting the word code in square brackets before the first line of code and the snippet /code in square brackets after the last line of code. That will preserve your indentation and make it much easier for us to read.

Just posting requirements and code isn't enough. You also need to indicate what isn't working the way you want. Does the code not compile? Do you not understand error messages? Is there a run time error and if so of what type? Do you not understand how to use a switch statement or some other programming tool? Etc.

In quickly looking at your code I notice that you apparently think the a single = means equals. For better or worse, in C/C++ a single = means assign the value on the right hand side of the = to tho the variable on the left hand side of the = sign. If you want to indicate equals rather than assignment, you must use two = signs in sequence. So = means assignment and == means equals. Therefore, if you want to compare variables in a conditional such as a while() or an if() or whatever, you want to use the == and not the = sign.
