C DEBUGGING QUESTIONS PDF CODE

(To move faster through code, we show you some other options as well.) By default, the debugger skips over non-user code (if you want more details, see Just My Code). The yellow arrow represents the statement on which the debugger paused, which also suspends app execution at the same point (this statement has not yet executed).ДЇ11 is a good way to examine the execution flow in the most detail. When you start the app with F11, the debugger breaks on the first statement that gets executed. F11 is the Step Into command and advances the app execution one statement at a time. To start your app with the debugger attached, press F11 ( Debug > Step Into). (Equivalent commands such as menu commands are shown in parentheses.) We provide the keyboard shortcuts for most commands because they make navigation of your app code quicker. Navigate code in the debugger using step commands If the app is not yet running, F5 starts the debugger and stops at the first breakpoint.Д«reakpoints are a useful feature when you know the line of code or the section of code that you want to examine in detail. Press F5 ( Debug > Start Debugging) or the Start Debugging button in the Debug Toolbar, and the debugger runs to the first breakpoint that it encounters. If you have a file open in the code editor, you can set a breakpoint by clicking in the margin to the left of a line of code. A breakpoint indicates where Visual Studio should suspend your running code so you can take a look at the values of variables, or the behavior of memory, or whether or not a branch of code is getting run. Breakpoints are the most basic and essential feature of reliable debugging. However, right now you may not have set any breakpoints to examine your app code, so we will do that first and then start debugging. F5 ( Debug > Start Debugging) is the most common way to do that. To debug, you need to start your app with the debugger attached to the app process. The features described here are applicable to C#, C++, Visual Basic, JavaScript, and other languages supported by Visual Studio (except where noted). If this is the first time that you've tried to debug code, you may want to read Debugging for absolute beginners before going through this topic. You can step through your code and look at the values stored in variables, you can set watches on variables to see when values change, you can examine the execution path of your code, et al. When you do this, the debugger provides many ways to see what your code is doing while it runs. In the Visual Studio context, when you debug your app, it usually means that you are running the application with the debugger attached (that is, in debugger mode).

This topic introduces the debugger tools provided by Visual Studio.
