The Complete C C++ Debugging Handbook for Visual Studio Code

Programmers primarily use the fundamental programming languages C and C++ in embedded and system software to improve speed and gain more control over the hardware. However, it might be difficult for novices to write error-free code with this language. Debugging plays a vital role in identifying, analysing, and resolving errors in the code. Let’s see about the C programming in VS Code, also through this blog.

The majority of pupils encounter problems such as incorrect outputs, infinite loops, and segmentation errors. Gaining a thorough understanding of debugging will enhance your comprehension of program execution and enable you to correct problems effectively. Visual Studio Code is a lightweight, free, and effective editor that is simple to use even for novices. These factors make it very advantageous for the students. Through the FITA Academy‘s organised education, students can improve their debugging abilities and obtain hands-on experience with Visual Studio Code.

Step 1: Install Visual Studio Code

Setting up a debugging environment in Visual Studio Code is crucial. Let’s begin with the installation procedure first. First, go to the official website and download and install Visual Studio Code. You can inspect and install the extension in the Microsoft C C++ extension by pressing Ctrl+Shift+X after installation. Both the IntelliSense activation and debugging processes will benefit from this.

MinGW is a GNU compiler that Windows users need to install. Adding it to a bin folder in the system environment is the next step. Make sure g++ is installed on your computer if you’re using a Mac or Linux. Lastly, to confirm that the C++ compiler has been downloaded and installed, open the g++ version. This command in VS Code helps with setup navigation.

Step 2: Write a Simple C C++ Program

After setting up the environment, you can now proceed with a simple C or C++ program to practice debugging.

  • Open the Visual Studio Code
  • Create a new file with a .c or .cpp extension.
  • Now you can begin with the regular program like “Hello World”
  • Now save the program as C_Programs,

Now you can easily locate the file in your system

You can learn how to handle logical errors, such as looping problems, and error handling, in this learning process. By participating in this practice session, the student will be able to identify their mistakes, track them down to comprehend the issues, and use the debugging tools to properly fix the flaws.

Step 3: Configure Debugging in VS Code

The learner must first install Visual Studio Code to attach the debugger to two essential files, launch.json and tasks.json, during the debugging process. Installing these two files as instructed. Let’s see how to run a C program in Visual Studio Code for handling system debug. Since this procedure is necessary and ought to be carried out once for every project, it will significantly facilitate the debugging process. By learning debugging from the Training Institute in Chennai, students can develop their projects in CC+ without bugs for application development.

Step-by-Step Configuration:

  1. Open your C C++ program in Visual Studio Code.
  2. Click on the Run and Debug icon on the left sidebar.
  3. Or press Ctrl+Shift+D .
  4. Click “Create a launch.json file”,
  5. Then choose C++ (GDB/LLDB) for Linux/Mac
  6. or C++ (Windows) if you’re using Windows.
  7. VS Code will generate a launch.json file inside a .vscode folder.
  8. Now, you need to define how your code should compile. Go to Terminal > Configure Default Build Task.
  9. Select C C++: g++ build active file (or a similar option, depending on your C compiler download).
  10. This will create a tasks.json file that includes compiler commands.
  11. In launch.json, make sure the “program” path points to the compiled .exe or output file.
  12. Set “args”, “cwd” (current working directory), and “stopAtEntry” as needed.

This setup enables you to set up the file efficiently. Because they automate the process of building and debugging. This cpp compiler and debugs the code after it is configured. Once established, all you have to do is click, which reduces development errors and saves time.

Step 4: Add C C++ Breakpoints

The breakpoint is a crucial stage in the debugging process. Once the configuration is complete, your code will begin debugging. Tell the debugger to halt execution at that line if you need your code to be tagged. By carefully examining variables, conditions, and flow, this procedure will help you identify any logical errors. Additionally, this approach is more straightforward for novices to undeand and is more interactive and visual.

Steps to Add Breakpoints and Debug:

  1. First, start by setting a Breakpoint
  2. Then, process the Debugging
  3. Use Debug Controls:
  4. Continue (F5): Runs code until the next breakpoint.
  5. Step Over (F10): Executes the following line without entering functions.
  6. Step Into (F11): Steps into the function to see what happens inside.
  7. Step Out (Shift + F11): Exits the current function and returns to the caller.
  8. Inspect Program Flow: Watch the yellow line indicator to follow code execution line by line.

Step 5: Watch C C++ Variables and Use Debug

We will examine the variables and the debugging procedure in this stage. For this phase, it is essential to understand what your software is doing in the background. There are two key elements in this process that are important for the debugging process: the Watch panel and the Debug Console. With the aid of these tools, you will be able to analyse the call stack, comprehend variable values, and even alter data in real time to test different situations. By learning it from the C C++ Training in Chennai or in major cities will help students to know more about the debugging process with expert guidance.

Steps to Watch Variables and Use Debug Tools:

  1. Open the Watch Panel
  2. Add Variables
  3. Check the Variables Panel
  4. Use the Call Stack.
  5. Use the Debug Console
  6. Identify Common Issue

As we’ve seen in this blog, some reasons to learn C++ language and about debugging is a crucial skills for any student interested in learning C C++ and needs to master it. Like any other skill, it gets better with practice. Even if we encounter many bugs in the process, it may annoy you. In the process, these bugs are an essential tool that will assist you in gaining a better understanding of the tools, enabling you to comprehend the structure and logic of programming.

With robust features like breakpoints, variable watchers, and the debug console, Visual Studio Code offers a free, lightweight, and user-friendly platform that simplifies debugging. Begin with simple initiatives, gain self-assurance, and then progressively take on increasingly complex tasks. You’ll become more adept and proficient at identifying and correcting mistakes if you put forth constant effort and exercise curiosity. Continue learning and developing!
