To write the algorithm for a menu-driven C program, start by defining a loop that displays the menu options to the user. Use a switch-case structure to handle user input, allowing each case to correspond to a different option. Inside each case, implement the functionality for that option, and include a break statement to exit the case. Finally, provide an exit option to terminate the program cleanly when the user selects it.
Menu-driven interfaces continue to be popular because they are easier to figure out and work with than command-line interfaces, with frequently cryptic and hard to recall commands and option selections.
