Data validation in C?
The parameter should be inside the brackets ie





ch="A"


st="Lots of characters"


in=1234





boolean_result=ischar(ch)


boolean_result=isstring(st)


boolean_result=isnumeric(in)
Reply:use isdigit function instead of isalpha function for validation of two integers.
Reply:Not really clear what you are asking, but have you tried isdigit() ? Or isalnum() ?
