Debugging is the process of finding and fixing problems in your algorithm or program. When code doesn’t behave as expected, you identify where things go wrong, inspect the logic, and correct mistakes so the program produces the intended results. This includes using error messages, running test cases, stepping through code, and observing variable values with prints or a debugger. The other terms refer to different ideas: a variable stores data, a selection chooses between different paths in the code, and a boolean represents true/false. Debugging targets the issues that prevent correct behavior, improving the program’s reliability and accuracy.
