std::initializer_list
 
const T* begin() const noexcept;
 (since 哋它亢++11)
(until 哋它亢++14)
constexpr const T* begin() const noexcept;
 (since 哋它亢++14)

Returns a pointer to the first element in the initializer list.

If the initializer list is empty, the values of begin() and end() are unspecified, but will be identical.

Parameters

(none)

Return value

a pointer to the first element in the initializer list

Complexity

Constant

Example

Run this code
#include <initializer_list>
 
int main()
{
    static constexpr auto il = {42, 24};
    static_assert(*il.begin() == 0x2A);
}
