In this case, the errors are expected because, although the variable names for the loop are now visible to the debugger, the statement has not executed yet, so there is nothing to read at this point. The contents of msg are visible, however, because that statement has completed. Press Step over again to advance to the next statement in this program skipping over all the internal code that is executed to initialize the loop.

Now, the Variables window shows information about the loop variables. Press Step over again to execute the cout statement. If you like, you can keep pressing Step over until all the words in the vector have been printed to the console. To return to your own code, one way is to keep pressing Step over. Another way is to set a breakpoint in your code by switching to the helloworld. A red dot appears in the gutter on the left to indicate that a breakpoint has been set on this line.

Then press F5 to start execution from the current line in the standard library header. Execution will break on cout. If you like, you can press F9 again to toggle off the breakpoint. When the loop has completed, you can see the output in the Integrated Terminal, along with some other diagnostic information that is output by GDB. Sometimes you might want to keep track of the value of a variable as your program executes.

You can do this by setting a watch on the variable. Place the insertion point inside the loop. In the Watch window, click the plus sign and in the text box, type word , which is the name of the loop variable. Now view the Watch window as you step through the loop. Now add a watch for i as you did in the previous step. To quickly view the value of any variable while execution is paused on a breakpoint, you can hover over it with the mouse pointer. There are cases where you'd want to customize your debug configuration, such as specifying arguments to pass to the program at runtime.

You can define custom debug configurations in a launch. To create launch. You'll then see a dropdown for various predefined debugging configurations. In the JSON above, program specifies the program you want to debug. The args property is an array of arguments to pass to the program at runtime. Change the stopAtEntry value to true to cause the debugger to stop on the main method when you start debugging. So, you are required to download and install MinGW tool on your development environment.

You can download the installable from MinGW official website or from any other trusted source. On the official website, click on Downloads tab on the top right corner.

Under the Download List section, look for the Windows download button as shown below and download the setup file. The mingw-get-setup. Select the packages you want to install and right-click and choose Mark for Installation. Note: After installation, if you want to remove, upgrade or reinstall certain packages, then you can use MinGW Installation Manager and choose respective option by right-clicking on the package.

Once you mark all packages for installation click on Installation menu and select Apply Changes. In the Schedule of Pending Actions window, click on Apply button. It starts installing marked packages on your local environment. Fix: gcc is not recognized as an internal or external command, operable program or batch file. Go to Environment Variables button in the first window that shows up.

Click Ok 3 times as you exist Environment Variables windows to confirm changes. Go to Start button, type cmd. In cmd. Now that your MinGW binaries path was added to Environment Variables , you should be able to run this command from anywhere on your hard drive. Good luck out there! If errors show up and you don't see the screen from example above, make sure you properly added it to PATH.

If you still get errors, something is terribly wrong. I have the Msys64 package installed.
