Solution for Exercise 16-9

ex1609

#include <stdio.h>

int verify(int check);

int main()
{
    int s;

    printf("Enter a value (0-100): ");
    scanf("%d",&s);
    if(verify(s))
    {
        printf("%d is in range.\n",s);
    }
    else
    {
        printf("%d is out of range!\n",s);
    }
    return(0);
}

int verify(int check)
{
    enum { false, true };

    if(check < 0 || check > 100)
        return false;
    return true;
}

Output

Enter a value (0-100): 999
999 is out of range!
