Dividing a program into modules serves the primary purpose of simplifying code maintenance and management. When a program is broken down into smaller, self-contained components or modules, it becomes easier for developers to work on individual pieces of the system without having to understand the entire codebase.

This modular approach allows for distinct functionality to be developed, tested, and debugged independently. As a result, changes to one module can often be made with minimal impact on other parts of the program, promoting easier updates and modifications. Furthermore, this fosters better organization of code, which can enhance collaborative work among teams, as multiple developers can work on different modules simultaneously.

While improving security, increasing execution speed, or enforcing coding conventions are beneficial aspects of programming practices, they are not the primary reasons for utilizing a modular programming approach. The essence of modularity lies in enhancing maintainability and facilitating more manageable development cycles.
