Understanding Some one else's code - beginner

[Slain]

I am a new hire in a company and have started working for the
development team. Ofcourse, I took some C++ courses in my grad school,
but there is such a big difference in the programs you encounter at
school versus here, where it sems there is a completely different
style of writing.

Is there some tool etc to help understand some one else's code. I have
been given some responsibilities to fix some minor defects, which
involves understanding some one else's code. Any pointers would be
helpful.

In addition to what has already been mentioned, the use of a code-folding
editor is usefull also as it gives a high level view of a source file and
then detail on demand. This is especially usefull in C++ because the norm is
to put all member functions of a given class in the same file and the
code-folding editor makes it a lot easier to work with (less scrolling and
searching and the like).
