std::invalid_argument(3cxx)

✨ std::invalid_argument ✨

okay bestie, welcome to the std::invalid_argument page from the libstdc++ manual — yes, that's the C++ standard library crew, and yes, this is the exception you'll be meeting a LOT 💅

🎀 SYNOPSIS 🎀

#include <stdexcept>

Inherits std::logic_error. That's its whole ancestry situation, periodt.

💖 Public Member Functions 💖

• invalid_argument (const char *) _GLIBCXX_TXN_SAFE — builds one of these bad boys from a C-style string, with _GLIBCXX_TXN_SAFE on it 🫶
• invalid_argument (const invalid_argument &)=default — copy ctor, and it's =default, so the compiler handles it, no notes ✨
• invalid_argument (const string &__arg) _GLIBCXX_TXN_SAFE — same energy but from a std::string named __arg, also _GLIBCXX_TXN_SAFE 💜
• invalid_argument (invalid_argument &&)=default — move ctor, =default, we love a no-effort queen 👑
• invalid_argument & operator= (const invalid_argument &)=default — copy assignment, =default 🎀
• invalid_argument & operator= (invalid_argument &&)=default — move assignment, =default 🦋
• virtual const char * what () const noexcept — the little virtual method that tells you what went down, noexcept so it can't throw at you, icon behaviour ⭐

🌈 Detailed Description 🌈

Thrown to report invalid arguments to functions. That's literally it — it's the "bestie, that argument? absolutely not" exception 😭 like when you pass something a function simply cannot deal with, and instead of quietly malfunctioning, the program throws one of these at you. Slay, honestly.

🦋 virtual const char * std::logic_error::what () const [virtual], [noexcept], [inherited]

Returns a C-style character string describing the general cause of the current error — and plot twist, it's the same string passed to the ctor 🍓 like, whatever you fed into the constructor? that's what comes back out. what() is giving main character energy, honestly.

• Reimplemented from std::exception
• Reimplemented in std::future_error
