Briefly describe any TWO advantages of using sub procedures or functions in aprogram. (5 Marks)

Sure! Here are two advantages of using sub procedures or functions in a program:

1. Code Reusability: One advantage of using sub procedures or functions is that they promote code reusability. By encapsulating a specific set of instructions within a sub procedure or function, you can easily reuse that code block multiple times throughout your program. This not only saves time and effort but also improves the overall maintainability of the code. Instead of writing the same code repeatedly, you can simply call the sub procedure or function whenever you need to perform a specific task.

2. Modular Programming: Another advantage of using sub procedures or functions is that they facilitate modular programming. Modular programming involves breaking down a complex program into smaller, more manageable modules or units. Sub procedures or functions act as these modules, allowing you to focus on developing and testing smaller sections of code independently. This makes the overall program structure more organized and easier to understand. Additionally, if any changes or updates are required, you can modify the specific sub procedure or function without affecting the rest of the program.

Overall, using sub procedures or functions in a program offers the benefits of code reusability and modular programming, making the code more efficient, maintainable, and easier to work with.
