public member function

std::vector::cend

<vector>
const_iterator cend() const noexcept;
Return const_iterator to end
Returns a const_iterator pointing to the past-the-end element in the container.

A const_iterator is an iterator that points to const content. This iterator can be increased and decreased (unless it is itself also const), just like the iterator returned by vector::begin, but it cannot be used to modify the contents it points to.

Unlike vector::end, this function returns a const_iterator even if the vector object is not itself const.

The value returned shall not be dereferenced.

Parameters

none

Return Value

A const_iterator to the element past the end of the sequence.

Member type const_iterator is a random access iterator type.

// vector::cbegin/cend
#include <iostream>
#include <vector>

int main ()
{
  std::vector<int> myvector = {10,20,30,40,50};

  std::cout << "myvector contains:";

  for (auto it = myvector.cbegin(); it != myvector.cend(); ++it)
    std::cout << ' ' << *it;
  std::cout << '\n';

  return 0;
}


Output:
myvector contains: 10 20 30 40 50

Complexity

Constant.

Iterator validity

No changes.

Data races

The container is accessed.
No contained elements are accessed by the call: concurrently accessing or modifying them is safe.
