In some terminology a vector can be described as a dynamic C-style array, it offers fast and efficient access to individual elements in any order and saves the user from worrying about memory and size allocation. Subscripting ( [] ) access is also provided as with C-style arrays.

std::vector< _Tp, _Alloc >::vector | ( | const vector< _Tp, _Alloc > & | __x | ) | [inline] |
Vector copy constructor.

std::vector< _Tp, _Alloc >::vector | ( | _InputIterator | __first, | |
_InputIterator | __last, | |||
const allocator_type & | __a = allocator_type() | |||
) | [inline] |
Builds a vector from a range.
first | An input iterator. | |
last | An input iterator. |
If the iterators are forward, bidirectional, or random-access, then this will call the elements' copy constructor N times (where N is distance(first,last)) and do no memory reallocation. But if only input iterators are used, then this will do at most 2N calls to the copy constructor, and logN memory reallocations.

void std::vector< _Tp, _Alloc >::assign | ( | _InputIterator | __first, | |

The advantage of this function is that if optimal code is a necessity and the user can determine the number of elements that will be required, the user can reserve the memory in advance, and thus prevent a possible reallocation of memory and copying of vector data.
