What is the process of identifying and fixing errors in a program called?

The process of identifying and fixing errors in a program is known as debugging. This involves systematically checking the code to find bugs, which are mistakes or flaws that cause the program to produce incorrect or unexpected results. Debugging can include using various tools and techniques to trace the program’s execution, monitor variable values, and analyze the flow of control to detect where things are going wrong.

Compiling refers to the process of converting source code written in a programming language into machine code that a computer's processor can execute. It does not involve error fixing, rather it often highlights syntax errors during the compilation step.

Testing is a broader term that involves running the program to ensure that it behaves as expected under various conditions. While it can involve identifying errors, it does not specifically address the fixing process, which is what debugging is focused on.

Updating generally refers to making changes to software to improve its functionality or security, or to add new features. It does not relate specifically to the identification or correction of errors within the existing code.

In summary, debugging specifically targets the detection and resolution of errors in a program, making it the correct term for this process.
