public member type

std::array::begin

<array>
      iterator begin() noexcept;
const_iterator begin() const noexcept;
Return iterator to beginning
Returns an iterator pointing to the first element in the array container.

Notice that, unlike member array::front, which returns a reference to the first element, this function returns a random access iterator pointing to it.

Parameters

none

Return Value

An iterator to the beginning of the sequence.

Member types iterator and const_iterator are random access iterator types.

// array::begin 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.begin(); it != myarray.end(); ++it )
    std::cout << " " << *it;

  std::cout << std::endl;

  return 0;
}


Output:
myarray contains: 2 16 77 34 50

Complexity

Constant.
