           num1=one;
           if(two = 0)

           else
              num2=two;
   }

   private:
   int num1;
   int num2;
};

Is that what you want to do?

I'm not sure I understand.  Do you just mean?

class number
   {
      public:
      number(int one=0,int two=1)
     {
         num1=one;
         if (two == 0)
            two = 1;
         num2=two;
     }

      private:
      int num1;
      int num2;
   };


let me know if you have questions.

in the code above : if(two = 0) is actually if(two == 0), but you already knew that.

Looks like jbalagop beat me to it.  I guess that is what you wanted, his thought was the same as mine.  He was slightly faster, so you might want to reject my answer so he can answer.

I forgot the ==  with one equal sign I was just assinging 0 to two, right?
Thanks for all your help

Yes, a single = assigns and a double == compares.

I am slowly starting to get the hang of this I think.
I wanted to thank everyone who answers my questions so quickly.

Thanks again.
