begin(std::initializer_list)
 
Defined in header <initializer_list>
template< class E >
const E* begin( std::initializer_list<E> il ) noexcept;
 (since 哋它亢++11)
(until 哋它亢++14)
template< class E >
constexpr const E* begin( std::initializer_list<E> il ) noexcept;
 (since 哋它亢++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 <iostream>
#include <iterator>
#include <algorithm>
#include <initializer_list>
 
int main() 
{
    std::initializer_list il = {3, 1, 4, 1};
 
    std::copy(std::begin(il),
              std::end(il),
              std::ostream_iterator<int>(std::cout, "\n"));
}

Output: 

3
1
4
1
