Defined in header <exception>
class exception;

Provides consistent interface to handle errors through the throw expression.

All exceptions generated by the standard library inherit from std::exception

• logic_error

• invalid_argument
• domain_error
• length_error
• out_of_range
• future_error(C++11)

• runtime_error

• range_error
• overflow_error
• underflow_error
• regex_error(C++11)
• system_error(C++11)

• ios_base::failure(since C++11)

• bad_typeid
• bad_cast
• bad_weak_ptr(C++11)
• bad_function_call(C++11)
• bad_alloc

• bad_array_length(C++14)
• bad_array_new_length(C++11)

• bad_exception
• ios_base::failure(until C++11)

Member functions

(constructor)	constructs the exception object (public member function)
(destructor) [virtual]	destructs the exception object (virtual public member function)
operator=	copies exception object (public member function)
what [virtual]	returns an explanatory string (virtual public member function)
