Question

Structured programming modules are used to segment tasks within the program. Based on some relevant web resources, Discuss the advantages of modularization. Explain what you learned from your readings and clearly state your reference/source of information.

Answer 1

Following are the advantages of modularization :-

1. Makes the coding easy. If we divide the large project into small modules and then work on each modules, then it will be much easier than considering entire project as single module. Code readability is easy.

2. Program debugging is easy. Since large projects have several lines of code and hence debugging over entire program will be very complex task, but if we do the debugging over separate modules, then the task will be easy.

3. Module testing is easy. Correctness of entire program depends upon correctness of individual modules and hence to test the correctness of a module, we just need a driver program and some test cases sufficient to cover all the possible input to the modules and hence testing becomes very easy with modularization.

4. Version updation is easy. Since large projects have several versions which improves several modules. So when update of particular module is available, we need to just replace the previous version with the next version, while keeping the rest part of project same as earlier.

5. Modularization improves code reusability. Dividing the program into small modules based on some functionality will improve code reusability whenever required.
