Question

What's a bug?
What's debugging?

Answer 1

A bug refers to an error, fault or flaw in any computer program or a hardware system.
A bug produces unexpected results or causes a system to behave unexpectedly.

➝ In short it is any behavior or result that a program or system gets but it was not designed to do.

Debugging checks, detects and corrects errors or bugs to allow proper program operation according to set specifications.
