runtime_error Class

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

Syntax

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

    explicit runtime_error(const char *message);

};

Remarks

The value returned by what() is a copy of message.data(). For more information, see what and data.

Example

// runtime_error.cpp
// compile with: /EHsc
#include <exception>
#include <iostream>
#include <locale>
#include <typeinfo>
using namespace std;

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