size_type size() const noexcept;		(since C++11) (until C++14)
constexpr size_type size() const noexcept;		(since C++14)

Returns the number of elements in the initializer list, i.e. std::distance(begin(), end()).

Parameters

(none)

Return value

the number of elements in the initializer list

Complexity

Constant

Example

Run this code

#include <initializer_list>
int main() { static_assert(std::initializer_list{1,2,3,4}.size() == 4); }
