Debugging Basics

Debugging is the art of finding and fixing bugs (errors) in your program. It's an essential skill for every developer.

DEBUG BY PRINT

Inserting cout statements to track variable values and program flow. Simple but effective for small bugs.

USE A DEBUGGER

Using tools like GDB or VS Code debugger to step through code line-by-line and inspect memory in real-time.

PRO TIP

Always try to reproduce the bug with the smallest possible input. This makes it much easier to isolate the cause.
