C Exercises: Compute the sum of the three given integers. However, if any of the values is in the range 10..20 inclusive then that value counts as 0, except 13 and 17

C-programming basic algorithm: Exercise-31 with Solution

Write a C program to compute the sum of the three given integers. However, if any of the values is in the range 10..20 inclusive then that value counts as 0, except 13 and 17.

C Code:

#include <stdio.h>
#include <stdlib.h>
int main(void){    
    printf("%d",test(4, 5, 7));
    printf("\n%d",test(7, 4, 12));
    printf("\n%d",test(10, 13, 12));
    printf("\n%d",test(13, 12, 18));
    }       
    int test(int x, int y, int z)
        {
            return fix_num(x) + fix_num(y) + fix_num(z);
        }    
    int fix_num(int n)
        {
            return (n < 13 && n > 9) || (n > 17 && n < 21) ? 0 : n;
        }

Sample Output:

16
11
13
13

Previous: Write a C program to compute the sum of the three integers. If one of the values is 13 then do not count it and its  right towards the sum.
Next: Write a C program to check two given integers and return the value whichever value is nearest to 13 without going over. Return 0 if both numbers go over.
