range_error Class

The class serves as the base class for all exceptions thrown to report a range error.

Syntax

class range_error : public runtime_error {
public:
    explicit range_error(const string& message);
    explicit range_error(const char *message);
};

Remarks

The value returned by what is a copy of message.data. For more information, see basic_string::data.

Example

// range_error.cpp
// compile with: /EHsc /GR
#include <iostream>
using namespace std;
int main()
{
   try
   {
      throw range_error( "The range is in error!" );
   }
   catch (range_error &e)
   {
      cerr << "Caught: " << e.what( ) << endl;
      cerr << "Type: " << typeid( e ).name( ) << endl;
   };
}
/* Output:
Caught: The range is in error!
Type: class std::range_error
*/
