Defined in header <initializer_list>
template< class E > const E* begin( std::initializer_list<E> il ) noexcept;		(since C++11) (constexpr since C++14)

The overload of std::begin for initializer_list returns a pointer to the first element of il.

Parameters

il

-

an initializer_list

Return value

il.begin()

Example

Run this code

#include <algorithm>
#include <initializer_list>
#include <iostream>
#include <iterator>
 
int main()
{
    std::initializer_list ϕ = {'1', '.', '6', '1', '8', '0'};
 
    std::copy(std::begin(ϕ),
              std::end(ϕ),
              std::ostream_iterator<char>(std::cout, ""));
 
    std::cout << '\n';
}

Output:

1.6180
