since C++14

// Const version
constexpr T* begin() const noexcept;

until C++14

Returns a pointer

to the first element in the initializer list.

If the initializer list is empty, the returned pointer will be equal to end().

Parameters

(none)

Return value

Pointer to the first character.

Complexity

Constant - O(1).

Example

Main.cpp

#include <initializer_list>

int main()
{
    static constexpr auto il = {42, 24};
    static_assert(*il.begin() == 0x2A);
}
