.
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.

|
Builds a vector from a range.
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. Definition at line 257 of file stl_vector.h. |

The dtor only erases the elements, and note that if the elements themselves are pointers, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibilty. Definition at line 272 of file stl_vector.h. References std::_Destroy(). |
|
Assigns a range to a vector.
Note that the assignment completely changes the vector and that the resulting vector's size is the same as the number of elements assigned. Old data may be lost. Definition at line 316 of file stl_vector.h. |

Erases all the elements. Note that this function only erases the elements, and that if the elements themselves are pointers, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibilty. Definition at line 748 of file stl_vector.h. |

Returns true if the vector is empty. (Thus begin() would equal end().) Definition at line 458 of file stl_vector.h. |

Remove a range of elements.
Note This operation could be expensive and if it is frequently used the user should consider using std::list. The user is also cautioned that this function only erases the elements, and that if the elements themselves are pointers, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibilty. Definition at line 122 of file vector.tcc. References std::_Destroy(), _Vector_base::_M_impl, std::copy(), and vector::end(). |

Remove element at given position.

Removes last element. This is a typical stack operation. It shrinks the vector by one. Note that no data is returned, and if the last element's data is needed, it should be retrieved before pop_back() is called. Definition at line 623 of file stl_vector.h. |

Attempt to preallocate enough memory for specified number of elements.
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.
