Question

What is the diffrence beatween say:

Vector<int*> myVector[5] and Vector<int> *myVector[5]

The way I see it, in the first case, my vector will contain 5 counts of pointers to ints.
In the second case, myVector is a pointer to an array of 5 ints.

The reason I ask is because I wrote some code a while back and now I don’t understand it any more.

With Vector<int> *myVector[5], why can I do

for(int i = 0; i < 5; i++)
        {
            myVector[i] = new Integer(13);
        }

I know for a fact that the operator new returns a pointer, and then I’m storing it in myVector, but a pointer to an int is not an int right?
I’m confused.

Answer 1

Vector<int*> myVector[5]

Creates an array of size 5 to Vector<int*>.

 Vector<int> *myVector[5]

Creates an array of 5 pointers to Vector<int>.
Instead, Using vector to vector is a cleaner soution:

vector<vector<int> > myVector(5);
