    What are even the point of vla's? Couldn't you just use new? Aren't vla's allocated on the heap like new?

    What C++ features are you needing compiled into a C program, is probably the most important question that seems to have gone unanswered thus far? You should be using a C++ compiler to compile code that is a "mix" of the two languages OR you should be using a linker to link object files that are compiled using each respective language into one binary.

    Whatever you are doing, you are probably not asking the appropriate question to accomplish the task.

    AFAIK, they can be allocated on the stack.

    Obviously in the examples so far, they've been on the stack, and it's irrelevant if it's the heap or the stack.

    VLAs are not an initializer feature. They have nothing to do with initializers.

    Also, they're on the stack. They're not allowed in global or member contexts. That makes them very useful for small-ish buffers where you know the size at runtime only.
    All the buzzt!
