C++ keyboard error checking

C++ keyboard error checking

(OP)
I am currently writing a mathematical C++ program, and have become stuck at a vitalpoint. I dont no how to perform a keyboard error check which will except numbers, and refuse characters without going into a infinite loop.I also want the program to ask the user to re-enter the data if a illegal character is entered. I am fairly new toto C++ and would appreciate any help.

RE: C++ keyboard error checking

    There are several ways to do this. Show us the code that you are stuck on (a small snippet please).
