Swift

A simple command-line calculator built in Swift.
This is my first Swift project — a small but fun way to learn the language.

• Basic arithmetic: addition, subtraction, multiplication, and division
• Input validation (handles invalid numbers and division by zero)
• Clean CLI interface
• Easily extendable for new operations

1. Clone the repository:

   git clone https://github.com/YOUR_USERNAME/swift-cli-calculator.git
   cd swift-cli-calculator

2. Run the calculator:

   swift main.swift

Example:

Welcome to Swift CLI Calculator!
Enter first number: 5
Enter second number: 3
Choose operation (+, -, *, /): *
Result: 15

swift-cli-calculator/
│── main.swift # Source code
│── README.md # Project documentation
│── .gitignore # Ignored files

• Add support for more operations (modulus, power, square root)
• Allow continuous calculations until user exits
• Format results with decimals
• Add tests
