    It is illegal because C++ requires compile-time constant values to be used for the array size when you declare a local array like you did. If you use a dynamic array (with new), then you can give it a variable size.

    Since the OP mentioned "pure c", it was not a bad suggestion, it is legal in C, but since this is a C++ forum, it just needs to be noted that it is not (yet) legal in C++ and many compilers won't allow it.

    Looking beyond legality, there are many articles on the difference between runtime memory and compile-time memory. You should look into them as that information is quite essential to programming.

    I posted 2 minutes after you. If you knew the difference, you wouldn't have posted such a fundamental mistake. Get your act together before you start mouthing off, kid.

    My god, you're a bit thin-skinned aren't you? I wouldn't have thought even the most sensitive soul would take "It is non-standard C++" as a flame, but there you go. Harden up, boy.

    If you program in C++, you need Boost. You should also know how to use the Standard Library (STL). Want to make games? After reading this, I don't like WxWidgets anymore. Want to add some scripting to your App?
