Variable pointer vs array

[future]

I want to know what would be better/faster, if I need to send 32 vars/bytes in a row via serial port, is it better to have an array with an indexing variable or I declare all 32 variables and use a pointer to the first var and an indexing variable?

like:

byte index
byte vars[32]
puts(vars[index])
index++

or:

byte pointer
byte index
byte var1
...
...
byte var32
pointer=address of var1
puts(pointer+index)
index++

A pointer to memory is larger than a byte. An array that exist in a simgle bank of memory may use a single byte as an index. You should compile code that does both and compaire the list file. Either way you go it will be much faster than the serial port can send or recieve.

[future]

It will be implemented using serial interrupts, once one byte is sent, the index is incremented and sent another byte.

I�m new to C, that is why the �pseudo code�, I need to read more about it.

My question is about how to access the values in ram memory.

To further muddy the waters, you could use a UNION to access the same memory locations both ways....
