How to use the Subtraction Operator In C++
Here simply use the subtraction operator between two numbers, two times so that minus-minus multiplies and produce the + operator, and return the sum of the numbers.
sum = A - (-B)
C++ Program to Add Two Numbers Using the Subtraction Operator
C++
// C++ program to add two number // using subtraction operator #include <iostream> using namespace std; // Function to return sum // of two number int addTwoNumber( int A, int B) { // Return sum of A and B return A - (-B); } // Driver Code int main() { // Given two number int A = 4, B = 11; // Function call cout << "sum = " << addTwoNumber(A, B); return 0; } |
Output
sum = 15
- Time complexity: O(1)
- Auxiliary Space: O(1)
