💖 std::begin(...alizer_list)(3) — C++ Standard Libary 💖

okay bestie, welcome to the std::begin(...alizer_list)(3) page from the C++ Standard Libary manual. it’s giving “tiny utility, main character energy” and we’re gonna get into every detail fr fr. 💅

✨ NAME ✨

std::begin(std::initializer_list) — std::begin(std::initializer_list)

---

🌸 Synopsis 🌸

Defined in header <initializer_list>.

Era 1, since C++11 and until C++14:

template< class E >
const E* begin( std::initializer_list<E> il ) noexcept;

Era 2, since C++14:

template< class E >
constexpr const E* begin( std::initializer_list<E> il ) noexcept;

The overload of std::begin for initializer_list returns a pointer to the first element of il. lowkey iconic, no cap. ✨

🎀 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"));
}
