# Command-Line Calculator in Ruby 🚀
A simple command-line calculator built in Ruby that supports basic arithmetic operations like addition, subtraction, multiplication, and division. This calculator allows users to perform calculations interactively in the terminal or command prompt.
## Features ✨
- Supports basic operations: `+`, `-`, `*`, `/`.
- Handles division by zero with an error message.
- Interactive command-line interface.
- Repeats the calculation loop until the user decides to exit.
## Prerequisites 🔧
- Ruby (version 2.x or higher) installed on your system.
## CLI 🔧
## Installation 🛠️
1. **Clone the repository**:
```bash
git clone https://github.com/chrohangurjar/command-line-calculator.git
```
2. **Navigate to the project folder**:
```bash
cd command-line-calculator
```
3. **Run the program**:
In your terminal, run the following command to start the calculator:
```bash
ruby calculator.rb
```
## Usage 📱
Once the program starts, you will be prompted to choose an operation. The available operations are:
- `+` (Addition)
- `-` (Subtraction)
- `*` (Multiplication)
- `/` (Division)
You will also be asked to input two numbers for the calculation. After displaying the result, the program will prompt you again for the next operation or allow you to exit by typing `exit`.
### Example:
```bash
Welcome to Command-Line Calculator! 🚀
Choose an operation: +, -, *, /, or type 'exit' to quit.
Enter operation: +
Enter the first number: 5
Enter the second number: 3
Result: 8.0
Enter operation: /
Enter the first number: 10
Enter the second number: 0
Result: Error: Division by zero!
Enter operation: exit
Thank you for using the calculator! Goodbye! 👋
```
