C++ Exercises: Find the larger value from two positive integer values that is in the range 20..30 inclusive

C++ Basic Algorithm: Exercise-21 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.

Sample Solution:

C++ Code :

#include <iostream>

using namespace std;

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;
            }
        }

        
int main() 
 {
  cout << test(78, 95) << endl;  
  cout << test(20, 30) << endl;  
  cout << test(21, 25) << endl;  
  cout << test(28, 28) << endl;  
  return 0;    
}

Sample Output:

0
30
25
28
