What can I add to my function that will make sure only numerical input is added? This is not for homework.
ThanksCode:float num_check (float num_entd) { while((num_entd>1000) || (num_entd<0)) { printf("Please enter a valid weight between 0 and 1000 lbs\n"); scanf("%f", &num_entd); } return num_entd; }
