What is the main benefit of abstraction in programming?

It increases the program's complexity.
It eliminates unnecessary details.
It provides more lines of code.
It makes the code less readable.

The correct answer is: It eliminates unnecessary details.

Abstraction in programming serves as a powerful tool for managing complexity by focusing on the essential features of an object or process while ignoring the irrelevant details. By eliminating unnecessary details, programmers can create a simplified model that represents complex systems, making it easier to understand and work with. This process allows developers to build programs that are easier to modify, debug, and maintain, as they can focus on high-level operations instead of low-level implementation specifics. The effectiveness of abstraction improves both code reusability and collaboration among team members, who can work with clear interfaces without needing to grasp the intricate details of every component. As a result, abstraction helps streamline the development process and enhances the overall efficiency of programming.
