Capturing the result ofstd::minby reference produces a dangling reference if one of the parameters is a temporary and that parameter is returned: intn=-1;constint&r=std::min(n+2, n*2);// r is dangling Example Run this code

staticT min()throw(); (until C++11) staticconstexprT min()noexcept; (since C++11) Returns the minimum finite value representable by the numeric typeT. For floating-point types with denormalization,min()returns the minimum positive normalized value.Note that this behavior may be unexpected, espe...
