Better Pretty Printing of 2d arrays in VS Code Debugger - C++ - c++

Question

Hi,
I'm pretty to new to C++ programming on VS Code, so I have a couple of Questions to ask.
My Software Specs:
Linux, 64 bit, Deepin 15.9
VS Code 1.31.1
G++ - 8, GDB 7.12
Extension used : C/C++ IntelliSense, debugging, and code browsing by Microsoft
C++ Pretty Printing of 2D array
I have to debug a lot of multi-dimensional arrays while programming and thus I want to know a method on how to view a 2D array, in the 'variables' window('watch' window will also do), in the form of a matrix.
Currently my variable's window looks like this
I want it to resemble something like
I know that a 2D array can be viewed using the method posted here, but I want to view it inside the debug tab in VSCode. Is there any pretty printing method or code to help me accomplish my goal?
Random Message On The Terminal When Stopping The Debug Process
There is some sort of message that appears on the terminal after stopping the debug process of C++. This is what it looks like -
I switched from opening an external terminal for debugging to using the inbuilt one, since, after I stop the debug process, the above message is displayed and the terminal doesn't auto-exit, so I would have to close the terminal manually. This was not the case on windows, where the terminal would auto-exit after the debugging. Is there any way to prevent this message(It comes after the Debug finishes or is stopped)?
I want to use the external terminal for debugging, so is there a method to remove this error message, or auto-exit after debugging closes?
These are my *.json files

Any help is truly Appreciated!!

I guess your options are writing your own gdb pretty printer or switching to lldb and the following extension which allows advanced visualization: https://github.com/vadimcn/vscode-lldb/wiki/Data-visualization
