C Exercises: Find the larger value from two positive integer values that is in the range 20..30 inclusive, or return 0 if neither is in that range

C-programming basic algorithm: Exercise-12 with Solution

Write a C program to find the larger value from two positive integer values that is in the range 20..30 inclusive, or return 0 if neither is in that range.

C Code:

#include <stdio.h>
#include <stdlib.h>
int main(void){
    printf("%d",test(78, 95));
    printf("\n%d",test(20, 30));
    printf("\n%d",test(21, 25));
    printf("\n%d",test(28, 28));
    }       
  int test(int x, int y)
        {
              if (x >= 20 && x <= 30 && y >= 20 && y <= 30)
            {
                if (x >= y)
                {
                    return x;
                }
                else
                {
                    return y;
                }
            }
            else if (x >= 20 && y <= 30)
            {
                return x;
            }
            else if (y >= 20 && y <= 30)
            {
                return y;
            }
            else
            {
                return 0;
            }
        }

Sample Output:

0
30
25
28
