std::overflow_error

class overflow_error;
Overflow error exception

This class defines the type of objects thrown as exceptions to arithmetic overflow errors.

It is a standard exception that can be thrown by programs. Some components of the standard library also throw exceptions of this type to signal range errors.

It is defined as:
1
2
3
4
class overflow_error : public runtime_error {
public:
  explicit overflow_error (const string& what_arg);
};
1
2
3
4
5
class overflow_error : public runtime_error {
public:
  explicit overflow_error (const string& what_arg);
  explicit overflow_error (const char* what_arg);
};

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 runtime_error.

Exception safety

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