Problem Statement

Write a C++ program demonstrating function references to alias and invoke arithmetic functions.

Input Format

Two space-separated integers A and B.

Output Format

Print sum computed via function reference.

Constraints

-10000 <= A, B <= 10000

Sample Input

12 34

Sample Output

Explanation

C++ allows creating references to functions, acting as clean alternatives to function pointers.

Starter Code

#include <iostream>

int add(int a, int b) {
    return a + b;
}

int main() {
    int a, b;
    if (std::cin >> a >> b) {
        int (&funcRef)(int, int) = add;
        std::cout << funcRef(a, b) << "n";
    }
    return 0;
}
