标准 C++ 库中有哪些异常类

What exception classes are in the standard C++ library

提问by Mooing Duck

What are the exception classes that are included in the standard C++ library, and what should they be used for? I know there are a few new C++11 exceptions, but I'm not sure what they are or where they are.

标准 C++ 库中包含哪些异常类，它们应该用于什么？我知道有一些新的 C++11 例外，但我不确定它们是什么或它们在哪里。

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

In practice, most exceptions are custom exceptions derived from logic_errorand runtime_error. Not that these are neglected, but that many exceptions are domain specific.

实际上，大多数异常是从logic_error和派生的自定义异常runtime_error。并不是说这些被忽略了，而是许多例外是特定于领域的。

Keep in mind that an exception should reflect what went wrong and notwho threw it. (No "MyProgramException"s)

请记住，异常应该反映出了什么问题，而不是是谁抛出的。（没有“MyProgramException”）

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.
