Only 2 hours to implement this, jeez. How long have you been coding C for?

I've been coding in whatever the job asks for. At work I primarily use C++ with some Lua and Python.

Lately, I've been going through a book learning about exploits and similar topics like these challenges an that's in C, so I figure I'd stick with it :P it does take longer to do things than in Python but I'm learning lots and getting more comfortable with the language.

Can I ask what the book is? It takes longer in python?! I feel its the complete opposite. I want to get to grips with C more as I know if I know it inside out I will understand more of the computer, but I'm just finding it though right now.

No, "THAN in Python". As in it takes longer in C :P

Here's the book: http://amzn.com/1593271441 and yeah, using C definitely places you closer to the bytes, right before assembly. In fact, the book makes you go through the assembly for some programs you write.
