+## Basic Calculator
+
+The Basic Calculator C implementation is a simple command-line calculator that allows users to perform basic arithmetic operations, such as addition, subtraction, multiplication, and division. The calculator takes user input and displays the result of the specified operation.
+
+## AIM
+
+This project aims to provide an easy-to-understand example of how to build a basic calculator using C. It is a great starting point for people learning C programming and looking to practice fundamental concepts, such as functions, control flow, and user input.
+
+## Operations
+
+This are the following operations that can be performed with this calculator:
+
+- Addition: Perform addition of two numbers.
+- Subtraction: Perform subtraction of two numbers.
+- Multiplication: Perform multiplication of two numbers.
+- Division: Perform division of two numbers.
+
+## Usage
+
+Using this program run the following commands in your terminal:
+
+* Clone the Demo-Project repository using this command `git clone <link to Demo-Project repository> `
+* Change Directory to `samuelejalonibu` using this command `cd samuelejalonibu`
+* Compile the program using C compiler, use this command ` gcc *.c -o calculator`
+* Run the compiled executable using this command `./calculator`
+* Enter two numbers and an arithmetic operator when asked
+* Then you'll see your result
+
+## Example
+
+Here is an example of how to use the calculator:
+
+```
+Welcome to the Basic Calculator!
+Choose an operation:
+
+1. Addition
+2. Subtraction
+3. Multiplication
+4. Division
+Enter your operator: +
+
+Enter the first number: 10
+Enter the second number: 20
+
+Result: 10 + 20 = 30
+```
+
+Feel free to try out different operations and numbers to explore the calculator's functionality.
+
+---
+
+Happy calculating and keep exploring C programming!
