Hi! I am working on a program to add, subtract, multiply and divide fractions and I need some way to check that the numerators and denominators that the user enters are not non-integer values. Does anyone know the best way to do this? I checked out the isdigit() function, but the data type of the user input for the denominators and numerators are type int, not a string. Thanks in advance!

Smiles,
