runtime_error Class


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 {  
    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  
      locale loc( "test" );  
   catch ( exception &e )   
      cerr << "Caught " << e.what( ) << endl;  
      cerr << "Type " << typeid( e ).name( ) << endl;  
\* Output:   
Caught bad locale name  
Type class std::runtime_error
