Debugging is like being a detective in the world of coding. When you write computer programs, things might not always work perfectly. That's where debugging comes in – it's the process of finding and fixing mistakes, also known as bugs, in your code. Just like searching for clues to solve a mystery, debugging helps you solve the mystery of why your program isn't doing what you want it to.
Common Debugging Techniques:
Print Statements: You can add messages in your code to see what's happening at different points. It's like leaving notes for yourself to understand what's going on behind the scenes.
Reading Error Messages: When your program doesn't work, the computer gives you messages. Learning to read these messages gives you hints about what's wrong.
Trial and Error: Change parts of your code and see if the problem goes away. This helps you pinpoint where the bug might be hiding.
Checking Variables: Make sure your variables contain the right values. Sometimes, a small mistake in a variable can cause big problems in your program.
Breaking Down the Code: Divide your program into smaller sections and test each part separately. This makes it easier to find the exact spot where the problem is.
Asking for Help: Don't be afraid to ask your teacher or classmates for assistance. Sometimes, fresh eyes can see something you missed.

IDE Debugging Features
Breakpoints:
IDEs let you set breakpoints, specific lines where the program pauses. This helps examine variables and program status, aiding bug detection and understanding behavior.
Step Over, Step Into, Step Out:
IDEs allow step-by-step code execution. "Step Over" moves to the next line. "Step Into" explores functions' code. "Step Out" exits the function, returning to the caller.
Watch Windows:
IDEs have watch windows to track variable values. Add variables to spot anomalies and changes, understanding data manipulation and detecting issues.
Call Stack:
IDEs display the order and calls of functions in the call stack. This helps understand program flow, recursion, and nested function calls.
Console Output:
IDEs offer a console window to display program output and errors. Use it for debugging messages, verifying results, and understanding unexpected behavior causes.
Syntax Highlighting
Syntax highlighting enhances debugging by visually distinguishing code elements. It helps you quickly spot keywords, variables, and syntax patterns, making the debugging process more efficient and accurate.
