Why does left shift operation invoke Undefined Behaviour when the left side operand has negative value?
In C bitwise left shift operation invokes Undefined Behaviour when the left side operand has negative value. Relevant quote from ISO C99 (6.5.7/4) The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits are filled with zeros. If E1 has an unsigned type, the value of the result is E1× 2E2, reduced modulo on...
How to approach a function that has slightly different behavior when called the first time?
This is a very general programming question that I just want to put out there and see if anyone has any thoughts on it.

So how e...

How to get into "The zone"
Hi, As I see there are lots of bright people here, I'll ask away. I don't know if this question has been asked before - most probably it has been. Duplicate this if so.
