If I had a main (int argc, char *argv[]) and wanted to check argv[1] to see if there was a isalpha there what am I going to need to do because isalpha takes an int. Am i going to need to use atoi or what because I've never really used this function and I don't know if I would want to use atoi or argv[1][?] check the 2nd dimension on that argv[1].
