Edit: int buffer[100]; // :) buffer[10] = 666; or *(buffer + 10) = 666; Or perhaps they generate the same code?

They generate the same machine code. (Assuming buffer is of a integer or array type. If buffer is a user defined type, all bets are off.)

It takes the pointer, counts 10 elements down from where the pointer points to, getting a new pointer, and then dereferences the new pointer. It's the same as buffer[10] assuming that buffer is of pointer type.
