How It Works

1. User Input:

   • The user provides the source currency code (e.g., USD).
   • The user provides the target currency code (e.g., EUR).
   • The user enters the amount to convert.

2. Currency Lookup:

   • The program retrieves exchange rates for the specified currencies.
   • The amount is converted to USD using the source currency's exchange rate.

3. Conversion:

   • The amount in USD is then converted to the target currency using its exchange rate.

4. Output:

   • The program displays the converted amount in the target currency.

Building and Running

Prerequisites

• C Compiler: Ensure you have a C compiler installed, such as gcc.

Compilation

To compile the program, navigate to the directory containing currency_converter.c and use the following command:

git clone https://github.com/mdriyadkhan585/Currency-Converter-C
cd Currency-Converter-C

gcc -o currency_converter currency_converter.c

This will generate an executable file named currency_converter.

Running the Program

Execute the compiled binary with:

./currency_converter

Using the Program

1. Enter the Source Currency Code: Type the 3-letter currency code of the source currency (e.g., USD).
2. Enter the Target Currency Code: Type the 3-letter currency code of the target currency (e.g., EUR).
3. Enter the Amount: Provide the amount to convert in the source currency.

The program will display the converted amount in the target currency.

Example

./currency_converter
Enter the source currency code (e.g., USD): USD
Enter the target currency code (e.g., EUR): EUR
Enter amount to convert: 100
Converted amount: 93.00 EUR

This example converts 100 USD to EUR, displaying 93.00 EUR.

Customization

Updating Exchange Rates

To update exchange rates, modify the currencies array in currency_converter.c with the latest rates. Ensure that each currency's rate is updated relative to USD.

Adding New Currencies

1. Add the currency code, full name, and exchange rate to the currencies array.
2. Ensure that the new currency code follows the 3-letter format and update the rates accordingly.

Error Handling

The program handles:

• Invalid Currency Codes: If an invalid currency code is entered, the program will display an error message.
• Invalid Amounts: Non-numeric or negative amounts will trigger an error message.
