10.3. Copying vectorsΒΆ

There is one more constructor for vectors, which is called a copy constructor because it takes one vector as an argument and creates a new vector that is the same size, with the same elements.

vector<int> copy (count);

Although this syntax is legal, it is almost never used for vectors because there is a better alternative:

vector<int> copy = count;

The = operator works on vectors in pretty much the way you would expect.

Take a look at the active code below, which uses the copy constructor.
