A breakpoint will appear as a red circle in the left column of the text editor.
A breakpoint can be added in VS Code either by clicking in the left column of the text editor window or by pressing F9. This allows you to view the details of execution at that point in the program flow. Specific Steps for Debugging a C++ Application in VS Codeīreakpoints are used to pause the flow of your program at a specific point. This will be specific to the exact error cause. Once the source of the error is known, the code must be modified to correct it. If there is a specific method or function where the error is occurring, it should be run by itself to save time and complexity.īy using breakpoints and stepping, we move slowly through the code and monitor the values stored in memory, the call stack, and other execution details to identify the exact cause of the error. Isolating the error means narrowing down the source of the error as much as possible. Typically, thorough testing is necessary to find all problems within an application. Some, like a program crashing during startup, are immediately obvious, while others are more subtle. With the program compiled, you will be able to select "Run and Debug" from the Debug menu to launch the debugger.īugs and errors can come in all shapes and sizes. Launch.json Configuration File: Note “program” variable must be modified to point towards your programs executable (.exe file)įinally, compile the program using the desired compiler. Throughout this tutorial, the following C++ class is used as an example (vector.h): class Vector /Debug/pathfinder.exe", In this article you will learn how to debug using the C/C++ extension for VS Code, including advanced features like breakpoints, tracking variable values, and stepping.
Debugging can be a life-saver when it comes to discovering bugs or errors in your code.
