What Actually Debugging process do ? On Google it says \"
Debugging is -- literally -- the process of removing bugs from your program.
But first you need to find those bugs.
You can do that in different ways:
Once you've found the bug, you need to remove it. For that, you go back to your text editor and fix the code. That part doesn't use the debugger.
But, these days, most programmers use a combined editor/debugger (an IDE).
