What is refactoring in software engineering?
a) Improving code structure without changing its behavior
b) Writing documentation for the code
c) Fixing bugs in the software
d) Increasing the software’s performance
Answer:
a) Improving code structure without changing its behavior
Explanation:
Refactoring is the process of restructuring existing code without changing its external behavior. The goal is to improve the design, readability, and maintainability of the code.
Refactoring helps reduce technical debt, makes the code more understandable, and prepares it for future modifications without introducing new bugs. It is typically done as part of continuous development or maintenance efforts.
Examples of refactoring techniques include renaming variables for clarity, breaking large functions into smaller ones, and simplifying complex conditions.
