Hey everyone!

I'm looking for interesting bits of C or C++ code, smaller programs or functions. That I can read and learn from.

Not looking for hello world examples, more complex. An example of "Hey thats neat" would be donut.c (http://www.a1k0n.net/2011/07/20/donut-math.html)

Anybody else know of cool little gems like this?

Github.

I've found cool/interesting functions (and even one-liners) by browsing around randomly.

there is a reddit dedicated to small snippets of code called tinycode, but it does not focus in any particular language. Github maybe your best option.

coreutils is great if you're looking to buff up your c skills. http://www.gnu.org/software/coreutils/, just was looking over remove_suffix inside basename.c today actually.

If you want to learn C http://www.ioccc.org/ gives some nice examples.

If, on the other hand, you want to learn programming in C, do not use IOCCC sources as something to aim for :-). I haven't read any of it, but I suspect http://pdos.csail.mit.edu/6.828/2011/xv6.html will contain a wide complexity range of code.

A little-known operator in C++, the "goes to"-operator:

int i=4;

while(i --> 0) { cout << i; }

Actually that's just decrementing and comparing to 0: while((i--) > 0)
