Thread: atoi

I am trying to let the user enter only a choice of 1,2or3
if the user enters a letter I want to give an error message.

So far my program crashes if the user enters a char.

I tryed to use atoi but it did not solve the problem....how can I solve it.....

Code:

printf("   choice: ");
scanf("%d", &choice);

if (isalpha(choice))
      choice=atoi(choice);
      fprintf(stderr,"incorrect choice, try again!\n");
