Ok, I am now just being introduced to constructors and here "Cat Frisky(5)" is the Frisky constructor in the main(), ok so this sets the age, now I have a question, if I wanted to make a constructor to set Frisky's hight for example how would I go about it? I might not be making any sense to you here. I mean set the hight with a constructor in this same program, is that possible and if so, how does it work? Thanks in advance.
