We will discuss the top 5 practical coding debugging tools for 2023 in this article. These tools have been developed to make it faster and more useful to find and fix problems.

Debugging is important to verify the quality of our code. This allows us to find and fix errors that can cause random behavior and cracks. By fixing these errors, we will improve the reliability and power of our software, making it more useful to our users.

We can improve the performance and efficiency of our code by debugging. We will be able to improve the user experience and overall performance of our program by detecting and resolving performance issues.

There are many strategies and ideas we can use to make debugging less time-consuming and frustrating for us.

Reproduce the issue: Try to reproduce the issue consistently, so that you can isolate and diagnose the problem.
Use print statements: Add print statements to the code to track variables and understand the flow of the program.
Use a debugger: A debugger allows you to step through the code line by line, inspect variables, and set breakpoints.
Check the logs: Logging can help you understand what’s happening in your code and often provides useful information for debugging.
Isolate the problem: Try to isolate the problem to a single function or module to make it easier to debug.
Check the documentation: Check the documentation of the libraries and APIs you are using to ensure that you are using them correctly.
Rubber duck debugging: Explain your code and the problem you are trying to solve to a rubber duck or a colleague. This often helps to clarify your thoughts and find the solution.
Test incrementally: Test small changes to your code, so that you can quickly identify which change caused the issue.
Test with edge cases: Test your code with edge cases to ensure that it works correctly under different conditions.
Take breaks: If you get stuck, take a break and come back to the problem later with a fresh perspective.

These tips and tricks can make debugging easier and more efficient. By following them, you can save time and find the root cause of the problem faster.

Some popular debugging tools include:

1. GDB (GNU Debugger)

GDB, the GNU Debugger, is a powerful tool used by developers for debugging programs written in C and C++. It allows developers to inspect the state of a program at any given moment during its execution, which is useful for identifying and fixing errors in the code. GDB can be used to inspect variables and memory, trace program execution, and control the execution of the program.

GDB provides a command-line interface, which allows developers to enter commands to inspect and control the program. This makes it ideal for use in text-only environments, such as remote servers or in terminals.

In addition, GDB can also be integrated with other development tools, such as text editors and Integrated Development Environments (IDEs), to provide a more streamlined debugging experience.

Some of the key features of GDB include:

Support for multi-threaded programs
Support for core dumps and post-mortem debugging
Ability to inspect variables and memory
Breakpoints and watchpoints for controlling program execution
Support for remote debugging, which allows debugging of programs running on remote systems

GDB is widely used and is considered to be one of the most powerful and flexible debugging tools available. It is particularly useful for debugging complex, large-scale programs, and is an essential tool for any C or C++ developer.

2. Visual Studio Debugger

The Visual Studio Debugger is a debugger integrated with Microsoft Visual Studio, an Integrated Development Environment (IDE) for Windows development. For programmers working on Windows programs, including those created in C++, C#, and other.NET-based languages, it offers a complete debugging environment.

With the help of the Visual Studio Debugger, developers may easily investigate variables, call stacks, memory, and other debugging-related objects. Additionally, it offers functions like breakpoints, watchpoints, and tracepoints that give programmers control over how their code is executed and how it behaves.

Developers may transition between developing and debugging jobs with ease thanks to the Visual Studio Debugger’s integration with other Visual Studio capabilities like the code editor and the integrated development environment (IDE).

The access to other tools and services made possible by this integration, including performance profiling and code analysis, can be utilized in conjunction with the debugger to raise the overall standard of the code.

The following are some of the main attributes of the Visual Studio Debugger:

Support for parallel and multi-threaded debugging
the capacity to debug software running on distant systems
support for memory analysis and coding diagnostics
Integration with the historical debugging experience offered by IntelliTrace in Visual Studio
