Editor choice for debugging C++
Visual Studio's debugger is top-notch. Performance can suffer for larger projects though. CLion is pretty good also. Some people might recommend QT's IDE. VSCode is fast, but annoying to set up. More on reddit.com

Is there a painless way to debug code that makes heavy use of macros?
No, macros are terrible to debug. The larger the code base, the greater the headache. I hope someone has some good tips for you, because I think macros are neat but I try to avoid them. More on reddit.com

r/C_Programming on Reddit: Any good and easy-to-use C debuggers?
January 12, 2023 -

I could really use a c debugger that is easy to use and set up. I am just a beginner, so I doubt I'd be able to configure a debugger myself as the other posts recommend. I just need to paste my code and follow its logic and see how the variables change.

I am doing cs50 and its built-in debugger only works half of the time. It is laggy and doesn't even show the contents of arrays.
