💖 std::match_results::length(3) 💖

okay bestie, welcome to the C++ Standard Libary manual page, section 3 — manual name folded in right here so we don’t have to copy the header line, you’re welcome 💅. We’re talking about std::match_results::length, and it’s literally giving “how long is this match, actually?” energy. ✨

🌸 NAME 🌸

  • std::match_results::length — std::match_results::length

🌟 Synopsis 🌟

difference_type length( size_type n = 0 ) const;  (since C++11)

Returns the length of the specified sub-match. 🫶

  • If n == 0, the length of the entire matched expression is returned. 💯
  • If n > 0 && n < size(), the length of the n^th sub-match is returned. 🎀
  • If n >= size(), a length of the unmatched match is returned. 😭

The call is equivalent to (*this)[n].length(). No cap, that’s the whole vibe. 🌈

🦋 Parameters 🦋

  • n — integral number specifying which match to examine.

👑 Return value 👑

The length of the specified match or sub-match. That’s it, that’s the tea. 🍓
