Explain the concept of code duplication and its impact on program complexity.

Code duplication refers to the presence of identical or similar code segments in different parts of a program. It occurs when developers copy and paste code instead of creating reusable functions or modules. While code duplication may seem like a quick and easy solution, it can have significant impacts on program complexity.

Firstly, code duplication increases the size of the program. As the duplicated code segments are repeated in multiple places, the overall size of the program grows. This can make the codebase harder to manage and maintain, as any changes or bug fixes need to be applied to each duplicated segment separately. Additionally, the increased size of the program can lead to longer compilation times and increased memory usage.

Secondly, code duplication hinders code readability and understandability. When the same code is scattered throughout the program, it becomes difficult to comprehend the logic and flow of the code. This can make it challenging for developers to understand and modify the code, leading to potential errors and bugs. It also makes it harder for new developers to onboard and contribute to the project.

Furthermore, code duplication increases the risk of introducing inconsistencies and errors. If a bug is discovered in one duplicated segment and fixed, the other duplicated segments may still contain the bug. This can lead to inconsistent behavior and make it harder to maintain the correctness of the program. Additionally, if a change needs to be made to the duplicated code, it must be applied to each instance separately, increasing the chances of missing a segment or introducing inconsistencies.

In terms of program complexity, code duplication significantly increases the complexity of the codebase. It makes the code harder to understand, maintain, and modify. It also increases the likelihood of introducing bugs and inconsistencies. As a result, the overall complexity of the program increases, making it more challenging to develop, test, and debug.

To mitigate the impact of code duplication on program complexity, developers should strive to eliminate or minimize duplication by following best practices such as modularization, abstraction, and reuse. By creating reusable functions or modules, developers can reduce the size of the codebase, improve code readability, and make it easier to maintain and modify the program. Additionally, code review processes can help identify and eliminate code duplication during the development phase.
