*1. what is code reuse and why is it important?*

code reuse is the practice of using existing code in new applications or systems, rather than writing it from scratch. it's a fundamental principle of efficient software development.

*why is it important?*

*reduced development time:* leveraging existing code saves time and effort. you don't need to reinvent the wheel for common tasks.
*improved code quality:* well-tested and debugged code is often more reliable than newly written code. reused components have already been vetted.
*lower maintenance costs:* maintaining one shared component is generally easier than maintaining multiple copies of the same code. bug fixes and enhancements can be applied in one place and benefit all users.
*increased consistency:* reusing cod ...
