This assignment involves designing a currency converter program that allows users to convert various foreign currencies into US dollars based on their menu selection. The program must handle different currencies such as Canadian Dollars, English Pounds, E.U. Euro, and others, with appropriate prompts, input validation, and conversion calculations. It should also handle invalid inputs gracefully, display confirmation messages for conversions, and allow multiple conversions until the user decides to exit the program.

The development of a currency conversion program is a common task in introductory programming courses, serving as an effective way to understand user input, decision structures, and modular programming. This paper explores the design, implementation, and validation of such a program, focusing on converting various international currencies into US dollars, guided by the detailed specifications provided.

At its core, the program uses a menu-driven interface that prompts users to select their currency of interest. The menu displays options for converting Canadian Dollars, English Pounds, E.U. Euro, and other currencies to US dollars, along with an option to exit. User input is captured and validated to ensure appropriate selections. When an invalid menu option is entered, the program provides an error message prompting the user to check their selection and redisplay the menu.

The program architecture follows a modular structure, dividing the tasks into distinct modules: Main, Menu, Convert_Currency, and Display_Results. The Main module initializes variables and controls the workflow, repeatedly calling the menu display and processing modules until termination. The Menu module displays options and captures the user’s selection, while the Convert_Currency module performs the conversion calculations based on the selected currency. The Display_Results module outputs the converted amount with a clear message.

To exemplify, if the user selects Canadian Dollars, the program prompts for the amount. The conversion rate from Canadian Dollars to US Dollars, as provided, is 0.93. The program multiplies the input amount by this rate and displays the equivalent in US dollars. For example, an input of 200 Canadian Dollars results in approximately $194.55 US dollars. The program then asks whether the user wants to perform another conversion, allowing for multiple transactions within a single session.

In addition to successful conversions, the program must handle exceptional cases, such as negative input values and invalid selections. If an invalid international value or menu choice is entered, the program responds with appropriate error messages like “This selection is not valid” or “Please check your selection,” preventing further processing until valid input is received. This approach enhances program robustness and user friendliness.

The pseudocode outlines the primary flow and decision structures that underpin the implementation, including conditional statements for menu options, currency conversion ratios, and input validation. Notably, the repeated use of if-else statements or switch-case constructs streamlines the decision process, while modular functions encapsulate specific tasks, facilitating debugging and future enhancements.

In conclusion, this currency converter program exemplifies key programming principles such as modularization, input validation, and user interaction. Its design ensures a reliable and user-friendly experience, capable of accurately converting selected foreign currencies to US dollars. By adhering to the structured pseudocode and implementing comprehensive validation, the program effectively fulfills the assignment requirements, serving as a practical demonstration of basic programming skills in a real-world context.
