C++ Checking Data Types

When I input an integer value using cin >> , how can I implement error-checking to make sure an integer was entered?

Well easy, just use the ctype.h

You can use isdigit() or isalpha() function :)

I also have the feeling you want to know how to check the size of the datatype that was used, you can use the sizeof keyword to do that...

ie: a = sizeof b;

those two things should help ya out

Search the board, it has come up before. Look up cin.good(), cin.bad(), cin.fail().
