If you want to print several objects you need to separate them with << every time(it's the same with cin),sense that cout is an object from the ostream or stream class(I don't remember)so every time you write:
four<<something;
it calls the operator<< from the class and print what you wanted and also returns an ostream object incase you wanted to make a chain to prinr several items,which is why,if you want to print several items you need to separate it with<< for every object

Cout << "discriminate: " << endl;
Cout << abcSUM ;

That's the way it's supposed to be.

The problem is the result of 1 and 2 are always 0, am I doing something wrong?
