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

Code smell refers to certain characteristics or patterns in code that indicate potential problems or areas for improvement. These characteristics may not necessarily be bugs or errors, but they can make the code harder to understand, maintain, or extend. Code smells can include things like duplicated code, long methods or classes, excessive comments, or poor naming conventions.

The impact of code smells on program complexity is significant. When code smells are present, it becomes more difficult for developers to understand and modify the code. This can lead to increased time and effort required for maintenance and bug fixing. Code smells can also make it harder to add new features or make changes to the code, as the complexity and interdependencies of the codebase increase.

Furthermore, code smells can contribute to technical debt, which refers to the accumulation of suboptimal or poorly designed code over time. This can result in decreased code quality, reduced productivity, and increased risk of introducing bugs or errors.

Overall, code smells have a negative impact on program complexity by making the code harder to comprehend, modify, and maintain. It is important for developers to regularly identify and address code smells to improve code quality and reduce complexity.
