public member function
std::array::cbegin
<array>
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.
Return Value
A const_iterator to the beginning of the sequence.
Member type const_iterator is a random access iterator type.
Example
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

// 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 << std::endl;
return 0;
}

Output:
myarray contains: 2 16 77 34 50
