template< class E > const E* begin( initializer_list<E> il );		(since C++11)

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

Parameters

il

-

an initializer_list

Return value

il.begin()

Exceptions

noexcept specification:  

noexcept

  (since C++11)

Example

run this code

#include <iostream>
 
int main() 
{
    // range-based for uses std::begin and std::end to iterate
    // over a given range; in this case, it's an initializer list
    for (int i : {3, 1, 4, 1}) {
        std::cout << i << '\n';
    }
}

Output:

3
1
4
1
