<h3>About</h3>
This program accepts the side length of a square from the user, calculates the area using the standard formula (Area = side²), and displays the result. It's designed as a beginner-friendly project to demonstrate user input, variables, arithmetic operations, and formatted output in C programming.
<h3>Project Structure</h3>
<ul>
<li>Area_of_a_Square/</li>
<li>├── square.c</li>
<li>└── README.md</li>
</ul>
<h3>Sample Code</h3>
#include &lt;stdio.h&gt;

int main() {
 float side, area;

 printf("Enter the side length of the square: ");
 scanf("%f", &amp;side);

 area = side * side;

 printf("Area of the Square = %.2f", area);

 return 0;
}

<h3>How to Compile and Run</h3>
<h4>Using GCC</h4>
Compile the program:
gcc square.c -o square

Run the program:
Linux/macOS
./square

Windows
square.exe

<h3>Sample Output</h3>
Enter the side length of the square: 8

Area of the Square = 64.00

<h3>Formula Used</h3>
The area of a square is calculated by multiplying the side length by itself.
