Chapter 11: Problem 4

Explain why most menu-driven programs use a loop to redisplay the menu after the user's selected action has been performed.

Short Answer

Expert verified

Answer: Most menu-driven programs use a loop to redisplay the menu after the user's selected action has been performed to increase efficiency, simplify program structure, and provide a better user experience by allowing users to continually interact with the program without unnecessary interruptions. Loops help maintain the program flow and offer users a seamless experience, making the program more efficient and user-friendly.

Step by step solution

Introduction to Menu-driven Programs

Menu-driven programs are designed to provide users with a list of options or actions from which they can choose. They are commonly used in applications where the user needs to interact with the program by making choices or selections. The main purpose is to simplify and organize the program's functions so that users can easily navigate through and use it as needed.

Purpose of a Loop in Menu-driven Programs

A loop is a basic programming structure that allows a block of code to be executed repeatedly based on a certain condition. In the context of menu-driven programs, loops are essential for making the program more efficient and user-friendly by allowing the menu to be redisplayed after each chosen action is performed. This offers the user a chance to make additional choices and perform more actions without having to restart the program.

User Experience and Program Flow

When a user selects an action from a menu-driven program, that action is executed, and then the menu is redisplayed so that the user can make another selection or exit the program. Loops help maintain the program flow and provide a seamless user experience by enabling users to continue using the program as long as they want, without having to perform extra steps or navigate through complex structures.

Loop Efficiency

Using loops in menu-driven programs increases efficiency by reducing the amount of code required to implement the desired functionality. Instead of writing separate functions for each menu option and calling the functions explicitly, a loop can be used to repeatedly display the menu, take user input, execute the chosen action, and then display the menu again. This simplifies the code and helps to keep the program organized and easier to maintain.

Conclusion

In conclusion, most menu-driven programs use a loop to redisplay the menu after the user's selected action has been performed because it increases efficiency, simplifies program structure, and provides a better user experience by allowing users to continually interact with the program without unnecessary interruptions. Loops are a fundamental programming concept that enables the creation of more versatile and user-friendly programs.
