Function overloading in C++ and OOP with examples
In this tutorial, we will learn about the followings;
What is function overloading?
Function overloading is a technique that allows to define and use more than one functions with the same scope and same name. But each function has a unique, which can be derived from the followings;

#include <iostream> using namespace std; void Sum_T4Tutorials(int a, int b) { cout << "sum = " << (a + b); } void Sum_T4Tutorials(double a,
double b) { cout << endl << "sum = " << (a + b); } // Driver code int main() { Sum_T4Tutorials(4, 6); Sum_T4Tutorials(8.1, 7.4); return 0; } |
Output
sum = 10
sum = 15.5
