The task is to Add two number using ‘-‘ operator.
Examples:
Input : 2 3 Output : 5 Input : 10 20 Output : 30
The idea is simple, we subtract -b from a.
C++
// CPP program to add two numbers using // - operator. #include <bits/stdc++.h> using namespace std; // function to add two numbers. int add(int a, int b) { return a - (-b); } // Driver code int main() { int a = 2, b = 3; cout << add(a, b) << endl; return 0; } |
