Catching the 'Divide By Zero' exceptions

I was surprised to find that C++ does not catch divide by 0 exceptions by default. The code will crash when a divide by 0 situation occurs. As a result the only option is to write our own class or method to handle divide by 0 scenario. The example below shows how to handle the Divide by zero scenario and how to construct an exception.

//Program tested on Microsoft Visual Studio 2008 - Zahid Ghadialy
#include<iostream>

using namespace std;

class Division
{
public:
  double quotient(int numerator, int denominator);
private:

};

double Division::quotient(int numerator, int denominator)
{
  if(!denominator)
  {
    exception e("Divide by 0 exception");
    throw(e);
  }
  return (static_cast< double >( numerator ))/denominator;
}


int main()
{
  Division d;
  try
  {
    cout<<"1. (100/10) = "<<d.quotient(100, 10)<<endl;
    cout<<"2. (10/4) = "<<d.quotient(10, 4)<<endl;
    cout<<"3. (10/0) = "<<d.quotient(10, 0)<<endl;
    cout<<"4. (30/9) = "<<d.quotient(30, 9)<<endl;
  }
  catch(exception& e)
  {
    cout<<"Exception caught with cause :"<<e.what()<<endl;
  }
  return 0;
}

The output is as follows:
