std::runtime_error

Runtime error exception


This class defines the type of objects thrown as exceptions to report errors that can only be detected during runtime.

It is used as a base class for several runtime error exceptions, and is defined as:

1
2
3
4
 
class runtime_error : public exception {
public:
  explicit runtime_error (const string& what_arg);
};
 
1
2
3
4
5
 
class runtime_error : public exception {
public:
  explicit runtime_error (const string& what_arg);
  explicit runtime_error (const char* what_arg);
};

Its sibling class, logic_error, is used as a base for exceptions reporting an error that can be prevented before the program execution.

Members

constructor
The string passed as what_arg has the same content as the value returned by member what.

The class inherits the what member function from exception.

Exception safety

Strong guarantee: if the constructor throws an exception, there are no side effects.
