[Help]Concatenate byte arrays

Code:

byte one[] = { 1, 1 };
byte two[] = { 2, 4 };
byte three[sizeof(one) + sizeof(two)] = ?

I'm stumped on how to do this (efficiently). /:

I'm not sure if there is any way to do that at compile time without using #defines. I'm talking about something like this:

Code:

#define _ONE 1, 1
#define _TWO 2, 4
byte one[] = {_ONE};
byte two[] = {_TWO};
byte three[] = {_ONE, _TWO};

I'm sure there is a less hacky way to do it though.

[Help] Tags added, It's easier for us to know what it is you are looking for

I want to do this at run time O:

I know I can just iterate through each byte and assign it, but is there a function that does it for me? (a C++ function that may be more efficient or faster or something_

1. Don't double post.
2. The fastest you could get this at run-time would probably using memcpy to copy the bytes.

malloc & memcpy
