_Vector_impl | _M_impl |
A standard container which offers fixed time access to individual elements in any order.
_Tp | Type of element. |
_Alloc | Allocator type, defaults to allocator<_Tp>. |
Meets the requirements of a container, a reversible container, and a sequence, including the optional sequence requirements with the exception of push_front
and pop_front
.
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 an initializer list.
__l | An initializer_list. |

Create a vector consisting of copies of the elements in the initializer_list __l.

__first | An input iterator. |

__a | An allocator. |
Create a vector consisting of copies of the elements from [first,last).
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.

Attempt to preallocate enough memory for specified number of elements.
__n | Number of elements required. |
std::length_error | If n exceeds max_size() . |
This function attempts to reserve enough memory for the vector to hold the specified number of elements. If the number requested is more than max_size(), length_error is thrown.
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.

Resizes the vector to the specified number of elements.
__new_size | Number of elements the vector should contain. |
This function will resize the vector to the specified number of elements. If the number is smaller than the vector's current size the vector is truncated, otherwise default constructed elements are appended.

__x | Data with which new elements should be populated. |
This function will resize the vector to the specified number of elements. If the number is smaller than the vector's current size the vector is truncated, otherwise the vector is extended and new elements are populated with given data.

Swaps data with another vector.
__x | A vector of the same element and allocator types. |
This exchanges the elements between two vectors in constant time. (Three pointers, so it should be quite fast.) Note that the global std::swap() function is specialized such that std::swap(v1,v2) will feed to this function.
Whether the allocators are swapped depends on the allocator traits.
