getchreturns a character code. The character code for “0” is 48, not 0, although you can get away with using a character constant instead (since char constants are really integer constants) and that will be more readable. So:If you’re using Visual C++ (as your tags indicate), you may find the MSDN docs useful. For instance, you probably should be using
_getchinstead, or_getchwif you want to write software that can be used more globally. And in that same vein, you probably want to look atisdigit,isdigitw, and the like.
