Where to add -g flag in vs code for debugging - c

Question

I have two questions. I have just installed VS code and managed to make it compile C codes and show outputs. But I am not able to debug. When I add a breakpoint and Debug, Red circle greys out.
I read on github that adding a -g flag will work.
Q1. But where and how to add -g flag? I also read:
How to add compile flag -g to a make file?
But it passed over my head.

}
I tried to change args in tasks.json from -o to -g, but it also stopped it from compiling, which was at least working before. If I added besides -o, program still didn't debug.
Edit:
Q2. Plus also telll me if it's ok to add path of C++ in tasks.json here instead of C?
Because I couldn't find path for C. Tutorials on internet were for C++ and they told to set C++ path there. But I want to compile C codes and although they are compiling now.

Answer 1

You should add the flag, not replace the "-o" flag.
The -o flag tells the compiler the name of the output file.
So instead have e.g.
"-Wall", "-g", "try.c", "-o", "try"
