The project requires developing a currency conversion application that enables users to select among five international currencies, input the foreign currency amount, and receive the equivalent dollar value. This application serves a practical purpose for travelers and international users by providing quick and reliable currency conversions through a menu-driven interface. To ensure comprehensive understanding, the project encompasses several phases: requirements analysis, design, verification, validation, and test documentation.

Initially, the requirements analysis involves understanding user needs, the scope of supported currencies, and functional specifications. The design phase focuses on creating a user-friendly interface, developing flowcharts for input, processing, and output, and constructing a hierarchy chart to depict program modules. Verification verifies that each component functions as intended, while validation ensures the overall program meets user needs and performs accurately in real-world scenarios.

The core functionality of the application revolves around a menu system listing the five currencies: Canadian dollars, Mexican pesos, English pounds, Japanese yen, and French francs. This menu allows users to select the currency they are converting from. Next, the application prompts for the amount of foreign currency, performs the conversion based on predefined exchange rates, and displays the dollar equivalent. After displaying the result, the program loops back to the menu, allowing multiple conversions until the user chooses to quit.

The exchange rates are as follows: 1 U.S. dollar equals 1.4680 Canadian dollars, 9.5085 Mexican pesos, 1.6433 English pounds, 104.9200 Japanese yen, and 6.2561 French francs. Using these rates, the conversion calculations convert the foreign currency amount into dollars by dividing the foreign amount by the relevant rate, ensuring accurate and real-time applicable conversions.

Creating an Input-Process-Output chart ensures structured data handling: input includes user selection and amount, process encompasses calculations and conversions, and output displays the dollar amount. Similarly, a hierarchy chart will outline parent and subordinate modules—such as main menu processing, currency selection, conversion calculations, and result display—to facilitate systematic development and testing.

Incorporating verification and validation processes ensures the robustness of the application. Verification checks include input validation, correct application of conversion formulas, and proper menu operation. Validation involves testing the application with sample data to confirm that the outputs are accurate, reliable, and align with user expectations. Test documentation will record test cases, results, and any issues encountered.

Overall, this structured approach guarantees that the currency conversion application is functional, accurate, user-friendly, and ready for deployment. It will assist users in making quick, reliable currency conversions in an international travel context, supporting the overall objective of simplifying financial dealings across borders.
