vector::pointer confusion

[Kristofer Pettijohn]

I'm hoping someone can help me understand the vector:ointer..

What is the correct way to go about going from:

std::vector<char> myCharVector(30);

to a char* ? (bad example, but char *myCharArray = _______ .... )

Thanks!

If myCharVector is going to stay around (and you're not going to add anything
to it that would cause a reallocation):

char* myCharArray = &myCharVector[0];

Otherwise, you're going to have to allocate a 30 element char array and copy
the contents into it.
