Hey,
Yes, array arguments are just simple pointers in C, so sizeof will return the size of a pointer to the base type. Exercise for the reader: Predict what happens when you try passing an int[4] into an int[8] argument.

Under "normal conditions" sizeof of an array covers the whole array. is this different for function paramters?
