What does it mean to "debug" a program?

To "debug" a program specifically refers to the process of identifying and fixing problems or errors in the code. Debugging is a crucial phase in software development and programming, as it ensures that the program functions as intended and meets the desired requirements. During debugging, developers utilize various techniques and tools to locate bugs, which may arise from logical errors, syntax mistakes, or incorrect assumptions made during the coding process.

By systematically addressing these issues, programmers can improve the functionality and stability of the software, ultimately leading to a more reliable and efficient program. Debugging can involve various strategies, such as reviewing code line by line, using debugging tools to inspect program state, and testing different scenarios to pinpoint where problems occur.

This understanding highlights why the choice reflecting "identifying and fixing problems" is the most accurate definition of debugging, as it captures the essence of the troubleshooting and correction process fundamental to coding and software development. In contrast, running a program without errors, optimizing performance, and thoroughly documenting code, while important aspects of software development, do not encapsulate the specific action of debugging.
