Domain error exception

| |
domain_error |
This class defines the type of objects thrown as exceptions to report domain errors.
Generally, the domain of a mathematical function is the subset of values that it is defined for. For example, the square root function is only defined for non-negative numbers. Thus, a negative number for such a function would be a domain error.
This class is designed so that any program, not just the elements of the standard library, can throw it as an exception.
It is defined as:

class domain_error : public logic_error {
public:
explicit domain_error (const string& what_arg);
};

Members
- constructor
- The constructor takes a standard string object as parameter. This value is stored in the object, and its value is used to generate the C-string returned by its inherited member what.
The class inherits the what member function from exception, along with its copy constructor and asignment operator member functions.
