Add Two Integers to Get Third

Write a C++ program to check if it is possible to add two integers to get the third integer from three given integers.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

// Function to check if the sum of any two numbers equals the third number
bool test(int x, int y, int z)
{
    return x == y + z || y == x + z || z == x + y;
}

int main() 
{
    // Testing the 'test' function with different sets of numbers
    cout << test(1, 2, 3) << endl;
    cout << test(4, 5, 6) << endl;
    cout << test(-1, 1, 0) << endl; 
    return 0;      
}

Sample Output:

1 
0
1
