Use function overloading to reuse functions

Function overloading is an important concept in C++. Sometimes, we want to use the same function name but have different functions to work on different data types or a different number of types. This is useful as the client can choose the correct function based on its needs. C++ allows us to do this by using function overloading.

Getting ready

For this recipe, you will need a Windows machine with a working copy of Visual Studio.

How to do it…

In this recipe, we will learn how to overload a function:

1. Open Visual Studio.
2. Create a new C++ project.
3. Select a Win32 Console Application.
4. Add source files called main.cpp, Cspeed.h, and Cspeed.cpp.
5. Add the following lines of code to main.cpp:

   #include <iostream>
   #include <conio.h>
   #include "CSpeed.h"
   
   using namespace std;
   
   
   
   //This is not overloading as the function differs only
   //in return type
   /*int Add(float x, float y)
   {
     return x + y;
   }*/
   
   int main()
   {
     CSpeed speed;
   
     cout&lt...
