please review my code and help

For starters, your code is missing semi-colons in your `else` statement. — Mike Lowery, Jul 15 '17 at 17:33

The compiler does not recognise cout in this context. You should refer the scope of cout with the scope operator ::

cout is part of the std namespace.

So wherever you have cout, substitute it with std::cout. The same is part with endl -> std::endl. The same applies to cin -> std::cin. Alternatively use '\n' instead of std::endl.

Just for further knowledge:

You could add using namespace std; in the top of your code. But, it is not normally suggested because of the best answer provided in this question.

And some advice:

Your switch statement is redundant, since you only evaluate if a value is ONE SINGLE option. You can change it with a normal if statement and then nest your existing if statement inside. Check switch statement documentation to see when it is more appropriate to use it.
