Function Overloading

Introduction

Function overloading is a feature in C++ that allows us to create multiple functions with the same name but different parameter lists. This means we can define multiple versions of a function, each catering to different data types or different numbers of parameters. This feature provides us with teh flexibility to create functions that perform similar operations on different data types or with different numbers of parameters.

In the following code, we have created two functions with the same name, i.e., sum but with a different number of parameters. The first function takes two integers as parameters, whereas the second function takes three integers.
