C++ Exercises: Check two given integers, each in the range 10..99

C++ Basic Algorithm: Exercise-50 with Solution

Write a C++ program to check two given integers, each in the range 10..99. Return true if a digit appears in both numbers, such as the 3 in 13 and 33.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

bool test(int x, int y)
        {
           return x / 10 == y / 10 || x / 10 == y % 10 || x % 10 == y / 10 || x % 10 == y % 10;
        }
        
int main() 
 {
  cout << test(11, 21) << endl;  
  cout << test(11, 20) << endl;  
  cout << test(10, 10) << endl;  
  return 0;    
}

Sample Output:

1 
0 
1

Previous: Write a C++ program to check three given integers and return true if one of them is 20 or more less than one of the others.
Next: Write a C++ program to compute the sum of two given non-negative integers x and y as long as the sum has the same number of digits as x. If the sum has more digits than x then return x without y.
