Final answer:
Choosing a modular structure for programming allows for easy isolation of issues, simplifies debugging, and supports code reuse. It enables easier maintenance and collaboration among developers by splitting the program into distinct modules.
Step-by-step explanation:
When a programmer chooses to make a program modular instead of non-modular, it divides the program into separate components, or modules, each of which handles a specific aspect of the program's functionality. This modular approach makes the program easier to fix when an error is found because it allows for isolating issues within a particular module without affecting the rest of the application. Therefore, identifying and fixing bugs becomes a more straightforward process, as the narrowed-down context reduces the complexity of the debugging task.
In addition, modular programming supports code reuse, making it easier to understand and maintain over time. Similarly, when multiple developers are working on a project, they can focus on different modules, minimizing the chances of code conflicts and easing the integration process. This compartmentalized structure promotes better organization and clearer logic, which in turn accelerates the maintenance and enhancement of the program.
