runtime_error Class

 

The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at runtime_error Class.

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
