A simple command-line currency conversion application built using C programming.
Currency Converter is a beginner-friendly console application that allows users to convert amounts between different international currencies. The project focuses on implementing real-world logic using C concepts such as user input handling, validation, conditional statements, and structured programming.
The application provides a simple terminal-based experience where users can select their source currency, enter an amount, choose a target currency, and receive the converted value instantly.
Supports conversion between:
- 🇮🇳 Indian Rupee (INR)
- 🇺🇸 US Dollar (USD)
- 🇩🇪 Euro (EUR)
- 🇬🇧 British Pound (GBP)
- 🇯🇵 Japanese Yen (JPY)
The program handles:
- Invalid country names
- Incorrect amount values
- Invalid conversion choices
- Same currency conversion attempts
Users can:
- Enter their current currency
- Provide conversion amount
- Select target currency
- View converted result
The project demonstrates clean implementation of:
- Variables
- Conditions
- Loops
- String handling
- User input processing
