What are the differences between using array offsets vs pointer incrementation?

Question

Given 2 functions, which should be faster, if there is any difference at all? Assume that the input data is very large

void iterate1(const char* pIn, int Size)
{         


        

Answer 1

Why don't you try both and time them? My guess would be that they are optimized by the compiler into basically the same code. Just remember to turn on optimizations when comparing (-O3).
