    I realize it may have further meanings and can indeed mean both things, but I will have to disagree.
    In C, you can only pass by pointer. It's etched into the language.

    Also, if you're talking programming languages, it's better to use programming-language specific words over more general ones.
    If I say, you should store a reference to that and that, it might imply, in C++, that you should actually store a reference, and not a pointer.

    So long story short, it's pass by pointer or nothing in my book, though not necessarily anyone else's.

    I concur with the majority opinion. C++ provides two ways to "pass by reference". Blame Stroustrup for calling one of them "reference" to confuse the issue.

    In C references (&) do not exist. Which I am well aware that you know. Bleh... laserlight, just close the thread.

    No, in C, you can only pass by value.

    The phrase is in the programming language literature.

    Thanks for the correction.
    Anyway, this is pointless. No more arguments from me.

    Likewise. No hostility or arguments here. I just hate to see stuff drag out aimlessly. This is what happens when beginners aren't posting fun to answer questions :P
