Constructors

vector

Constructs a vector of a specific size or with elements of a specific value or with a specific allocator or as a copy of some other vector.

Typedefs

allocator_type

A type that represents the allocator class for the vector object.

const_iterator

A type that provides a random-access iterator that can read a const element in a vector.

const_pointer

A type that provides a pointer to a const element in a vector.

const_reference

A type that provides a reference to a const element stored in a vector for reading and performing const operations.

const_reverse_iterator

A type that provides a random-access iterator that can read any const element in the vector.

difference_type

A type that provides the difference between the addresses of two elements in a vector.

iterator

A type that provides a random-access iterator that can read or modify any element in a vector.

pointer

A type that provides a pointer to an element in a vector.

reference

A type that provides a reference to an element stored in a vector.

reverse_iterator

A type that provides a random-access iterator that can read or modify any element in a reversed vector.

size_type

A type that counts the number of elements in a vector.

value_type

A type that represents the data type stored in a vector.

Member Functions

assign

Erases a vector and copies the specified elements to the empty vector.

at

Returns a reference to the element at a specified location in the vector.

back

Returns a reference to the last element of the vector.

begin

Returns a random-access iterator to the first element in the vector.

capacity

Returns the number of elements that the vector could contain without allocating more storage.

cbegin

Returns a random-access const iterator to the first element in the vector.

cend

Returns a random-access const iterator that points just beyond the end of the vector.

crbegin

Returns a const iterator to the first element in a reversed vector.

crend

Returns a const iterator to the end of a reversed vector.

clear

Erases the elements of the vector.

data

Returns a pointer to the first element in the vector.

emplace

Inserts an element constructed in place into the vector at a specified position.

emplace_back

Adds an element constructed in place to the end of the vector.

empty

Tests if the vector container is empty.

end

Returns a random-access iterator that points to the end of the vector.

erase

Removes an element or a range of elements in a vector from specified positions.

front

Returns a reference to the first element in a vector.

get_allocator

Returns an object to the allocator class used by a vector.

insert

Inserts an element or a number of elements into the vector at a specified position.

max_size

Returns the maximum length of the vector.

pop_back

Deletes the element at the end of the vector.

push_back

Add an element to the end of the vector.

rbegin

Returns an iterator to the first element in a reversed vector.

rend

Returns an iterator to the end of a reversed vector.

reserve

Reserves a minimum length of storage for a vector object.

resize

Specifies a new size for a vector.

shrink_to_fit

Discards excess capacity.

size

Returns the number of elements in the vector.

swap

Exchanges the elements of two vectors.

Operators

operator[]

Returns a reference to the vector element at a specified position.

operator=

Replaces the elements of the vector with a copy of another vector.
