    BLANKO meny with int v1.c

    There is a problem if you in

    scanf("%d",&choice);

    enter something else than 0-9. In that case, exit with Ctrl-Break.

    This is resolved as follows:

    int choice;
    char terminator;

    printf("\n Enter a number: ");

    // On success, the function scanf() returns the number
    // of items of the argument list successfully read.
    // If scanf didn't read two elements, integer and char, and return 2
    // or if second element terminator isn't enter '\n'
    // then first element isn't integer.
    if( scanf("%d%c", &choice, &terminator) != 2 || terminator != '\n' )
    {
        printf("\n choice = %d is not an integer ! \n");
        return(1);
    }
