Like everyone else I too prefer the second method one over the first as it is simpler, easier to understand and uses much less storage in the stack segment. Also I don't see the need for a function call just to malloc a chunk of memory. For an embedded system where resources are scarce you are better off mallocing that block of memory in main.
