In this post, we will learn** how to calculate the area of a square using C** Programming language.

This program asks the user to enter the** side** of the square, then it will calculate the **area of the square** by multiplying the side by itself.

So, without further ado, letâ€™s begin this tutorial.

**C Program To Calculate Area of a Square**

// C Program to Calculate Area of Square #include <stdio.h> int main(){ int side, area; // Asking for input printf("Enter the side of the square: "); scanf("%d", &side); // Calculating Square area = side * side; // Displaying output printf("Area of the Square having side %d is: %d", side, area); return 0; }

**Output**

```
Enter the side of the square: 7
Area of the Square having side 7 is: 49
```

**How Does This Program Work ?**

int side, area;

In this program, we have declared two** int data type** variables named **side** and **area**.

// Asking for input printf("Enter the side of the square: "); scanf("%d", &side);

Then, the user is asked to enter the side of the square.

// Calculating Square area = side * side;

**Area of Square = Side * Side**

// Displaying output printf("Area of the Square having side %d is: %d", side, area);

Finally, the area of the square is displayed to the screen using **printf()** function.

**Conclusion**
