# C++ Program to Find Out the Area of Square

In this tutorial, we will learn about the area of square i.e. how to find out the area of square using C++

So, here’s some quick information related to the program which can help you to know better, i.e. What actually it says?

## Quick Info:💡

↪ Square is a four-sided closed figure, with equal sides each angle of 90 degree. In other words we can say that, it is a rhombus with each angle 90 degree.

↪ We are provided with the side of the square and our task is to display the result as the area of the square on the output console.

↪ Steps to perform the above task:

• First, Input the side of the square.
• Second, Use the formula to find out the area i.e. Area=Side*Side
• Third, Display the result on the output screen.

↪ It can be done using different ways:

## Find Out Area of Square Using Direct Method

Here’s a direct method to print the output on the output screen.

Simply, the user will be asked to enter the input and the area of a square is computed and displayed to a user.

## Example:

``````#include<iostream.h>
#include<conio.h>
void main()
{
int side, area;
cout<<"Enter the side of a square:";
cin>>side;
area=side*side;
cout<<"Area of a square is:";
cout<<area;
getch();
}``````
``````//Output:
Enter the side of a square:5
Area of a square is: 25``````

## Working:

Here, we have seen the simple way to find out the area of square But, now let’s try another way to find out the result of the same program.

## Find Out Area of Square Using Function

Functions are used to perform certain actions, and they are important for reusing code: Define the code once and use it many times.

Here’s the method to find out the area of square using function.

Note: Always remember that execution starts from the main body only.

### Example:

``````#include<iostream.h>
#include<conio.h>
int area_of_square(int s)
{
int a=s*s;
cout<<"Area of square for "<<s<<" is: ";
return a;
}
void main()
{
int side1,side2;
cout<<"Enter the side of a square: ";
cin>>side1;
cout<<area_of_square(side1);
cout<<"\nEnter the side of a square: ";
cin>>side2;
cout<<area_of_square(side2);
getch();
}``````
``````//Output:
Enter the side of a square: 5
Area of square for 4 is: 25
Enter the side of a square: 7
Area of square for 6 is: 49``````
