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.
