    Equal compare

    Hello everyone,


    I want to confirm that on a 32-bit machine,

    1. compare the value of two byte to see whether they are equal or not;
    2. compare the value of two integer (4-byte) to see whether they are equal or not.

    (1) and (2) should have the same performance, right? I am using x86 32bit Windows machine to develop native unmanaged C++ application.


    thanks in advance,
    George

    That's true most of the time at least (always true for regular ints and longs).

    The only time it isn't true is when you have a pointer to int say, and that pointer isn't on a 4-byte boundary. On an X86, you just slow down a bit. On other machines, you get a bus error (see another recent post).
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
