overflow_error Class

The class serves as the base class for all exceptions thrown to report an arithmetic overflow.

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

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

// overflow_error.cpp
// compile with: /EHsc /GR
#include <bitset>
#include <iostream>

using namespace std;

int main( )
{
   try 
   {
      bitset< 33 > bitset;
      bitset[32] = 1;
      bitset[0] = 1;
      unsigned long x = bitset.to_ulong( );
   }
   catch ( exception &e ) 
   {
      cerr << "Caught " << e.what( ) << endl;
      cerr << "Type " << typeid( e ).name( ) << endl;
   };
}
Caught bitset<N> overflow
