In this post, we will learn how to calculate the area of a square using C++ Programming language.
Area of a square is calculated using the formula: Area = Side x Side.
We will calculate the area of a square using the following approaches:
- Using Standard Method
- Using Function
So, without any delay, let’s begin this tutorial.
C++ Program to Calculate Area of Square
// C++ Program to Calculate Area of Square
#include <iostream>
using namespace std;
int main(){
int side, area;
// Asking for input
cout << "Enter the side of square: ";
cin >> side;
// Calculating area
area = side * side;
// Displaying output
cout << "Area of square of side " << side << " is: " << area;
return 0;
}
Output
Enter the side of square: 7
Area of square of side 7 is: 49
How Does This Program Work ?
int side, area;
In this program, we have declared two integer data type variables named side and area.
// Asking for input
cout << "Enter the side of square: ";
cin >> side;
The user is asked to enter the length of the side. This value gets stored in the side named variable.
// Calculating area
area = side * side;
Area is calculated by using the formula, area = side x side. The result gets stored in the area named variable.
// Displaying output
cout << "Area of square of side " << side << " is: " << area;
The area of the square is displayed on the screen using the cout statement.
C++ Program to Calculate Area of Square Using Function
// C++ Program to Calculate Area of Square Using Function
#include <iostream>
using namespace std;
int areaSquare(int x){
return x * x;
}
int main(){
int side, area;
// Asking for input
cout << "Enter the side of square: ";
cin >> side;
// Calling out function
area = areaSquare(side);
// Displaying output
cout << "Area of the square is: " << area;
return 0;
}
Output
Enter the side of square: 12
Area of the square is: 144Conclusion
