  An exception can be of only built-In type is false statement.
  You can create user-defined exceptions. C++ provides a base class for all exception named as Exception. If you want to create your own exception then you have to inherit this class.
  class myException : public exception{
  
  public:
  
  const char * what() const throw()
  {
  
  return "Divide By Zero Exception occured\n";
  }
  };
  
  int main()
  
  {
  try
  {
  int a, b;
  cout << "Enter two numbers : ";
  cin >> a >> b;
  if (b == 0)
  
  {
  myException exp;
  
  throw exp;
  }
  else
  {
  
  cout << "a / b = " << a/b << endl;
  }
  
  }
  catch(exception& eObj)
  
  {
  
  cout << eObj.what();
  
  }
  
  }
  
  Exception class provide what() public method and it should be overridden by all the child exception classes.
