C++ Method Overloading Program

Hello Everyone!

In this tutorial, we will learn how to demonstrate the concept of Method Overloading, in the C++ programming language.

To understand the concept of Method or Function Overloading in CPP, we will recommend you to visit here: Function Overriding, where we have explained it from scratch.

Code:

#include <iostream>
#include <vector>
using namespace std;
//defining the class shape to overload the method area() on the basis of number of parameters.
class shape {
 //declaring member variables
 public:
 int l, b, s;
 //defining member function or methods
 public:
 void input() {
 cout << "Enter the length of each side of the Square: \n";
 cin >> s;
 cout << "\n";
 cout << "Enter the length and breadth of the Rectangle: \n";
 cin >> l >> b;
 cout << "\n";
 }
 //Demonstrating Method Overloading
 public:
 void area(int side) {
 cout << "Area of Square = " << side * side;
 cout << "\n";
 }
 void area(int length, int breadth) {
 cout << "Area of Rectangle = " << length * breadth;
 cout << "\n";
 }
};
//Defining the main method to access the members of the class
int main() {
 cout << "\n\nWelcome to Studytonight :-)\n\n\n";
 cout << " ===== Program to demonstrate Method Overloading in a Class, in CPP ===== \n\n";
 //Declaring class object to access class members from outside the class
 shape sh;
 cout << "\nCalling the input() function to take the values from the user\n";
 sh.input();
 cout << "\nCalling the area(int) function to calculate the area of the Square\n";
 sh.area(sh.s);
 cout << "\nCalling the area(int,int) function to calculate the area of the Rectangle\n";
 sh.area(sh.l, sh.b);
 cout << "\nExiting the main() method\n\n\n";
 return 0;
}

Output:

C++ method overloading
