~ symbol

hi,

I am just trying to find out what the ~ does,

e.g.
number = (number + 3) & ~3;

any help?

In the principle of "Give a man a fish, and he will ask for another the next day, teach a man to fish, and he will not need to ask for another fish", I'll give you a link for ALL C and C++ operators:
http://en.wikipedia.org/wiki/Operators_in_C_and_C%2B%2B

The one you are looking for is in the second section in the big table.
