creating a dynamic array?

    keyMain= new Key_Node[X];
    for(int i=0; i<X; i++)
    {
        keyMain[i].key=i;
        cout << keyMain[i].key<<endl;
        keyMain[i].next_package=NULL;
    }

Am I doing it right here? I am not sure about it. It seems like the right thing to do, but can anybody confirm? Thank you.X is the number inputted by the user.

Yes, you can certainly do that, provided the array is not expected to grow or shrink.

Otherwise, std::vector (see here) is probably a better choice. C++ provides some powerful collection classes in its standard library and everyone who professes to know the language should be familiar with them.
