About

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.

Project Structure

• Area_of_a_Square/
• ├── square.c
• └── README.md

Sample Code

#include <stdio.h> int main() { float side, area; printf("Enter the side length of the square: "); scanf("%f", &side); area = side * side; printf("Area of the Square = %.2f", area); return 0; }

How to Compile and Run

Using GCC

Compile the program:

gcc square.c -o square

Run the program:

Linux/macOS

./square

Windows

square.exe

Sample Output

Enter the side length of the square: 8 Area of the Square = 64.00

Formula Used

The area of a square is calculated by multiplying the side length by itself.

Requirements
