    Tell me to go back to the C board if you want but is this legal in C++?
    Almost. It is legal, but it should not compile because nothing has been initialized.

    int main(){
      int x = 5;
      int arr[x];
      return 0;
    I don't think so. I think x should be constant. Someone please correct me if I'm wrong, but I believe the standard way to dynamically allocate an array is:
    int x = 5;
    int* arr = new int[x];
    And VS 2003 won't compile it:
    error C2057: expected constant expression
    error C2466: cannot allocate an array of constant size 0
    error C2133: 'array' : unknown size

    I move we create a seperate topic when referring to what VS doesnt like and put it in its own forum.. because VS's a loner.
