runtime_error Class

 

For the latest documentation on Visual Studio 2017, see Visual Studio 2017 Documentation.

The class serves as the base class for all exceptions thrown to report errors presumably detectable only when the program executes.

class runtime_error : public exception {  
public:  
    explicit runtime_error(const string& message);

    explicit runtime_error(const char *message);

};  

The value returned by exception Class1 is a copy of message.data.

// runtime_error.cpp  
// compile with: /EHsc /GR  
#include <iostream>  
  
using namespace std;  
  
int main( )  
{  
// runtime_error  
   try   
   {  
      locale loc( "test" );  
   }  
   catch ( exception &e )   
   {  
      cerr << "Caught " << e.what( ) << endl;  
      cerr << "Type " << typeid( e ).name( ) << endl;  
   };  
}  
\* Output:   
Caught bad locale name
