Area of Rectangle Example C++ Program in C++

About this program

This is an example program in c common example program. Read the concept first: C++ Variables and Data Types, then study the code and output below.

Definition

The area of the rectangle is the length multiplied by the width.

Area Of Rectangle Formula

The area of a rectangle is written as,

A=l*b

where,
A=Area
l=length
b=breadth

Area Of Rectangle Example Program

/*## Area Of Rectangle In C++*/
/*## Calculation C++ Programs, Datatype C++ Programs, Basic C++ Programs*/

#include <iostream>
#include<conio.h>
#include<stdlib.h>

using namespace std;

int main() {
   // Declare Variables
   int length, breadth, area;

   cout << "Simple C++ Program : Area Of Rectangle\n";
   cout << "\nEnter the Length of Rectangle : ";
   cin>>length;

   cout << "\nEnter the Breadth of Rectangle : ";
   cin>>breadth;

   area = length * breadth;
   cout << "\nArea of Rectangle : " << area;

   getch();
   return (0);
}

Sample Output

Simple C++ Program : Area Of Rectangle

Enter the Length of Rectangle : 5

Enter the Breadth of Rectangle : 3

Area of Rectangle : 15

How It Works

This C++ program demonstrates Area of Rectangle Example. It first reads the required values as input, then performs the core operation step by step, and finally prints the output shown in the Sample Output above.

1. Declare the variables that hold the program’s data.
2. Read the input values that the program will work with.
3. Print the final result to the console so you can compare it with the sample output.

Try changing the input values and re-running the program to see how the output changes — this is the fastest way to understand how the logic behaves.
