#172185 - Pointer vs Index?
Responding to: ???'s previous message
Neil Kurzman said:
I suppose you could use pointers instead. Not sure which would be more efficient on an 8052.


I'm not sure, either!

But the thing is: the 8052 doesn't have an "indexed" addressing mode; so, to access an array element by index, it has to take the array's base address, and the index, and then use the resulting address to access the required element - which sounds rather like it'd be little more (nor less) efficient than using a pointer!
