You may make an argument for that abomination in C when perform prototypes were being scarce to ensure banning:
void check(string& s) Nefarious n; // difficulty brewing string copy = s; // copy the string // wipe out copy after which you can n
This operate is by most measure way too extensive in any case, but the point is that the means utilized by fn as well as the file manage held by is
Right here, copying s could throw, and if that throws and if n’s destructor then also throws, the program will exit by way of std::terminate for the reason that two exceptions can’t be propagated simultaneously.
