member func: cbegin

defination

const_iterator cbegin() const noexcept;

Return const_iterator to beginning

Returns a const_iterator pointing to the first element in the array 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 array::begin, but it cannot be used to modify the contents it points to, even if the array object is not itself const.

Parameters

none

Return Value

A const_iterator to the beginning of the sequence.

Member type const_iterator is a random access iterator type that points to a const element.

example

// array::cbegin example
#include <iostream>
#include <array>

int main ()
{
  std::array<int,5> myarray = { 2, 16, 77, 34, 50 };

  std::cout << "myarray contains:";

  for ( auto it = myarray.cbegin(); it != myarray.cend(); ++it )
    std::cout << ' ' << *it;   // cannot modify *it

  std::cout << '\n';

  return 0;
