Jakie klasy wyjątków znajdują się w standardowej bibliotece C++

Question

Jakie są klasy wyjątków uwzględnione w standardowej bibliotece C++ i do czego mają one służyć? Wiem, że jest kilka nowych wyjątków C++ 11, ale nie jestem pewien, czym one są i gdzie się znajdują.

Answer 1

std::exception <exception> interface (debatable if you should catch this) 
    std::bad_alloc <new> failure to allocate storage 
     std::bad_array_new_length <new> invalid array length 
    std::bad_cast <typeinfo> execution of an invalid dynamic-cast 
    std::bad_exception <exception> signifies an incorrect exception was thrown 
    std::bad_function_call <functional> thrown by "null" std::function 
    std::bad_typeid <typeinfo> using typeinfo on a null pointer 
    std::bad_weak_ptr <memory> constructing a shared_ptr from a bad weak_ptr 
    std::logic_error <stdexcept> errors detectable before the program executes 
     std::domain_error <stdexcept> parameter outside the valid range 
     std::future_error <future> violated a std::promise/std::future condition 
     std::invalid_argument <stdexcept> invalid argument 
     std::length_error <stdexcept> length exceeds its maximum allowable size 
     std::out_of_range <stdexcept> argument value not in its expected range 
    std::runtime_error <stdexcept> errors detectable when the program executes 
     std::overflow_error <stdexcept> arithmetic overflow error. 
     std::underflow_error <stdexcept> arithmetic underflow error. 
     std::range_error <stdexcept> range errors in internal computations 
     std::regex_error <regex> errors from the regular expression library. 
     std::system_error <system_error> from operating system or other C API 
      std::ios_base::failure <ios> Input or output error

W praktyce większość Wyjątkiem są niestandardowe wyjątki pochodzące z logic_error i runtime_error. Nie że są one zaniedbane, ale że wiele wyjątków dotyczy konkretnej domeny.

Należy pamiętać, że wyjątek powinien odzwierciedlać, co poszło nie tak i , a nie, który go rzucił. (Nie "MyProgramException" s)

Exception    Description 
=================================== 
std::exception   An exception and parent class of all the standard C++ exceptions. 
std::bad_alloc   This can be thrown by new. 
std::bad_cast   This can be thrown by dynamic_cast. 
std::bad_exception  This is useful device to handle unexpected exceptions in a C++ program 
std::bad_typeid   This can be thrown by typeid. 
std::logic_error  An exception that theoretically can be detected by reading the code. 
std::domain_error  This is an exception thrown when a mathematically invalid domain is used 
std::invalid_argument This is thrown due to invalid arguments. 
std::length_error  This is thrown when a too big std::string is created 
std::out_of_range  This can be thrown by the at method from for example a std::vector and std::bitset<>::operator[](). 
std::runtime_error  An exception that theoretically can not be detected by reading the code. 
std::overflow_error  This is thrown if a mathematical overflow occurs. 
std::range_error  This is occured when you try to store a value which is out of range. 
std::underflow_error This is thrown if a mathematical underflow occurs.
