# C++ Program to Find Perimeter of a Square

Howdy readers, today you will learn how to write a C++ program to find the perimeter of a square.

The perimeter of a square is defined as the length that its boundary covers. The formula to calculate the perimeter of a square is given as: P = 4 x length of one side.

This tutorial prompts the user to enter the side of a square, then it computes the perimeter using the mathematical formula:

• Perimeter of Square = 4 x Side

So, without any delay, let’s begin this tutorial.

## C++ Program to Find Perimeter of a Square

C++ Program

```// C++ Program to Find Perimeter of a Square
#include <iostream>
using namespace std;

int main(){
int side, pm;

// Taking input
cout << "Enter the side of the square: ";
cin >> side;

// Calculating perimeter of square
pm = 4 * side;

// Display perimeter
cout << "The perimeter of the square is: " << pm << endl;

return 0;
}
```

Output

```Enter the side of the square: 15
The perimeter of the square is: 60
```

Explanation

```    int side, pm;
```

We have declared two int data type variables named `side` and `pm` in this program.

```    cout << "Enter the side of the square: ";
cin >> side;
```

The side of the square is taken as input from the user. The entered value gets stored in the `side` named variable.

```    pm = 4 * side;
```

The perimeter of the square is calculated using the formula: Perimeter of square = 4 x side. The perimeter gets stored in the pm named variable.

```    cout << "The perimeter of the square is: " << pm << endl;
```

At last, the perimeter of the square is printed on the screen using the cout statement.

## Conclusion

Today you learned how to write a C++ program to find the perimeter of a square.
