Lecture 252:- Debugging Basics

Debugging is the process of finding and fixing errors or defects in software code. Debugging is an essential part of software development and is required to ensure that the software works as intended and that it is free from errors.

Debugging involves several techniques and tools that help developers identify the root cause of a problem in the code. Some of the basic debugging techniques include:

Print statements: This is the most basic and widely used debugging technique. It involves inserting print statements in the code to output the values of variables, functions, and other program elements at various points in the code. This helps developers understand the state of the program and track down bugs.
Debuggers: A debugger is a tool that allows developers to step through the code line by line, examine variables and memory, and set breakpoints to pause the program's execution at specific points in the code. Debuggers are integrated into most development environments and are a powerful tool for debugging complex programs.
Logging: Logging is a technique where developers insert messages into the code that are written to a log file at runtime. This helps developers understand the program's behavior and track down bugs. Logging is often used in production systems to track errors and monitor system performance.
Unit tests: Unit tests are automated tests that developers write to test individual components or functions of the program. Unit tests can help identify bugs early in the development process and ensure that the code works as intended.
Code reviews: Code reviews are a process where developers review each other's code to identify bugs, suggest improvements, and ensure that the code follows best practices. Code reviews are a collaborative and effective way to catch errors and improve code quality.

Debugging can be a time-consuming and challenging process, but with the right techniques and tools, developers can quickly identify and fix bugs, resulting in more robust and reliable software.
