[C/C++] vector api reference

Example

#include <iostream>
#include <vector>
 
int main()
{
    // Create a vector containing integers
    std::vector<int> v = {7, 5, 16, 8};
 
    // Add two more integers to vector
    v.push_back(25);
    v.push_back(13);
 
    // Iterate and print values of vector
    for(int n : v) {
        std::cout << n << '\n';
    }
}

Member Function Reference

Member functions

(constructor)	constructs the vector  (public member function)
(destructor)	destructs the vector  (public member function)
operator=	assigns values to the container  (public member function)
assign	assigns values to the container  (public member function)
get_allocator	returns the associated allocator  (public member function)
Element access
at	access specified element with bounds checking  (public member function)
operator[]	access specified element  (public member function)
front	access the first element  (public member function)
back	access the last element  (public member function)
data (C++11)	direct access to the underlying array  (public member function)
Iterators
begincbegin	returns an iterator to the beginning  (public member function)
endcend	returns an iterator to the end  (public member function)
rbegincrbegin	returns a reverse iterator to the beginning  (public member function)
rendcrend	returns a reverse iterator to the end  (public member function)
Capacity
empty	checks whether the container is empty  (public member function)
size	returns the number of elements  (public member function)
max_size	returns the maximum possible number of elements  (public member function)
reserve	reserves storage  (public member function)
capacity	returns the number of elements that can be held in currently allocated storage  (public member function)
