C, Objective C, or C++?

If I wish to pick one of the three to learn, which should I pick?

i'm learning C atm by writing me a DWARF FORTRESS so there will
be a huge amount of insightful threads for newbie C programmers
on /prog/ in the next couple of weeks.

my advice to you: don't just jump in, if you want to use a
feature you're not comfortable with yet then FIRST READ A
TUTORIAL. this will save you hours of work in GDB.

fucking pointer arithmetic.
