std::runtime_error
 
Defined in header <stdexcept>
class runtime_error;

Defines a type of object to be thrown as exception. It reports errors that are due to events beyond the scope of the program and can not be easily predicted.

Exceptions of type std:runtime_error are thrown by the following standard library components: std::locale::locale and std::locale::combine.

In addition, the standard exception types std::range_error, std::overflow_error, std::underflow_error, std::regex_error, and std::system_error are derived from std::runtime_error.
