What do you call the practice of removing errors in a program?

The practice of removing errors in a program is known as debugging. Debugging involves identifying and fixing issues, or "bugs," that prevent the program from operating as intended. This process may include running the code, analyzing error messages, and systematically isolating the problematic areas within the code to resolve them.

Testing refers to the broader process of evaluating the functionality of software to ensure it operates correctly and meets specified requirements. It encompasses checking for errors but does not specifically focus on the act of correcting those errors.

Coding is the actual writing of the code itself. While coding is part of the process of developing software, it does not involve identifying or fixing any existing errors but focuses on creating the application from scratch.

Deploying is the stage where the software is released to production or made available to users. This stage occurs after debugging and testing have been completed, ensuring that the program is error-free and functional before it is put into use.

Therefore, debugging stands out as the specific term for the practice of removing errors from a program.
