type problem

D.Q

alright guys, I was just wondering if anyone could help me out.

iv developed a simple program in c for a project.

for all of the user input choices, iv used ints.

but, now im on the error checking stage and if the user enters a char, the program gets all messed up.

I was wondering how to combat this? Iv searched online but everything is very complicated compared to what we have done so far.

any help would be really appreciated, as would an explanation so Im not just blindly copying:o

Without knowing more detail on the specific processing the user input undergoes in order to reach a result I can only suggest these two solutions:
1. cast the input to an integer (not a great solution if there's actualy merit to user input as opposed to just requesting an input to save using a random number generator);
2. apply a check to the input and if it isn't an integer instead of continuing the normal operation give a message to the user stating that only integer inputs are allowed.

As per point 2. above: Take in the input as a string or char[], check that each charachter is numerical using isdigit() and then convert the string/char[] to an int.
