std::ranges...t_view::end(3)

🎀 std::ranges...t_view::end(3) 🎀

okay bestie, welcome to the C++ Standard Libary corner of the internet — this page is all about std::ranges::split_view::end, and we’re gonna make it make sense 💅✨

🌸 NAME 🌸

std::ranges::split_view::end - std::ranges::split_view::end

🦋 Synopsis 🦋

constexpr auto end() const;  (since C++20)

This one returns an iterator or a sentinel representing the end of the resulting subrange. It’s giving range-terminator realness, no cap 😌

Equivalent to:

constexpr auto end()
{
    if constexpr (ranges::common_range<V>)
        return /*iterator*/{*this, ranges::end(base_), {}};
    else
        return /*sentinel*/{*this};
}

💖 Parameters 💖

(none)

Literally nothing to pass here, bestie 🫶

✨ Return value ✨

An iterator or a sentinel. That’s the whole vibe check 🦋

🍓 Example 🍓

// Run this code

#include <iostream>
#include <ranges>
#include <string_view>

int main()
{
    constexpr std::string_view keywords{"bitand bitor bool break"};
    std::ranges::split_view kw{keywords, ' '};
    const auto count = std::ranges::distance(kw.begin(), kw.end());
    std::cout << "Words count: " << count << '\n';
}

Output:

Words count: 4

And yes, the example prints exactly that — four words, slay 🎀
