cppreference.com > C++ Vectors C++ Vectors Vectors contain contiguous elements stored as an array. Accessing members of a vector or appending elements can be done in constant time, whereas locating a specific value or inserting elements into the vector takes linear time. Display all entries for C++ Vectors on one page, or view entries individually:
Vector constructors | create vectors and initialize them with some data
Vector operators | compare, assign, and access elements of a vector
assign | assign elements to a vector
at | returns an element at a specific location
back | returns a reference to last element of a vector
begin | returns an iterator to the beginning of the vector
capacity | returns the number of elements that the vector can hold
clear | removes all elements from the vector
empty | true if the vector has no elements
end | returns an iterator just past the last element of a vector
erase | removes elements from a vector
front | returns a reference to the first element of a vector
insert | inserts elements into the vector
max_size | returns the maximum number of elements that the vector can hold
pop_back | removes the last element of a vector
push_back | add an element to the end of the vector
rbegin | returns a reverse_iterator to the end of the vector
rend | returns a reverse_iterator to the beginning of the vector
reserve | sets the minimum capacity of the vector
resize | change the size of the vector
size | returns the number of items in the vector
swap | swap the contents of this vector with another
