Please note, that this is not a homework site. We won't do your homework for you. However we are always willing to help solve problems you encountered, correct mistakes you made in your code and answer your questions.

We didn't see your attempts to solve this problem youself and so we cannot correct mistakes you didn't made and answer questions you didn't ask. To get help you should do something yourself and get real problems with something. If your problem is "I don't understand a thing", then you should go back to basics and study again. As it is impossible to find deriviative of function without knowledge in ariphmetics, you cannot do more complex tasks in programming without clear understanding of basics.

Why do you care if the user enters anything other than 'Y'? You give them a clear message that they have to enter 'Y' in order to repeat, it is their fault if they ignore the message.

std::string is part of C++ and should be one of the first things you are taught. If you are being taught C instead of C++, you should indicate that in your first post; you are on a C++ forum, and the default assumption is that you want C++ help.
