Currency Converter c++

To create a currency converter in C++, you can follow the steps below:

1. Include necessary header files: Begin by including the necessary header files, such as iostream and string, to allow input/output operations and string manipulation.

2. Declare variables: Declare variables to store the exchange rates and user input. For example, you can declare variables for the exchange rate from USD to EUR, the exchange rate from USD to GBP, and the amount of money in USD that the user wants to convert.

3. Get user input: Use the cin object to prompt the user to enter the exchange rates and the amount of money in USD. Store the input in the respective variables.

4. Perform the conversion: Multiply the amount of money in USD by the exchange rate to convert it to the desired currency. For example, if the user wants to convert USD to EUR, multiply the amount of money in USD by the exchange rate from USD to EUR.

5. Display the result: Use the cout object to display the converted amount to the user. You can format the output to include the currency symbol and decimal places.

6. Repeat or exit: Ask the user if they want to perform another conversion or exit the program. Use a loop to repeat the process if the user wants to convert again.

Here is an example of how the code might look:

#include <iostream>
#include <string>

int main() {
    double usdToEurRate, usdToGbpRate, amountUSD;

    std::cout << "Enter the exchange rate from USD to EUR: ";
    std::cin >> usdToEurRate;
    std::cout << "Enter the exchange rate from USD to GBP: ";
    std::cin >> usdToGbpRate;
    std::cout << "Enter the amount in USD to convert: ";
    std::cin >> amountUSD;

    double amountEUR = amountUSD * usdToEurRate;
    double amountGBP = amountUSD * usdToGbpRate;

    std::cout << "Converted amount in EUR: " << amountEUR << std::endl;
    std::cout << "Converted amount in GBP: " << amountGBP << std::endl;

    return 0;
}

This code prompts the user to enter the exchange rates from USD to EUR and GBP, as well as the amount of money in USD to convert. It then performs the conversion and displays the converted amounts in EUR and GBP.
