Shared Digit Between Two Integers (Range 10–99)

Write a C++ program to check two given integers. Each integer is 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;

// Function 'test' takes two integers (x, y) as parameters
bool test(int x, int y)
{
    // Checks if the tens place of x equals the tens place of y
    // OR if the tens place of x equals the ones place of y
    // OR if the ones place of x equals the tens place of y
    // OR if the ones place of x equals the ones place of y
    return x / 10 == y / 10 || x / 10 == y % 10 || x % 10 == y / 10 || x % 10 == y % 10;
}

int main() 
{
    // Testing the 'test' function with different sets of numbers
    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.
