    about your printOnScreen method: Shouldn't it take no arguments, and just print out the private memver `answer'? otherwise the last statement in main before system(pause) (o.printOnScreen(int answer);) is a syntax error :)

    private member* `answer' something like void Operation::printOnScreen() { cout << answer << endl; }

    This is the question Write a C++ program with multiple methods to intake the two integers and do the, Addition, Subtraction, Multiplication, and Division. Hints: 1.Use the following class diagram for your implementation. 2.On your main method u hav to implement selection and repetition of the arithmetic operation 3.You can include any more methods if required.

    ah I get it now. you need to either declare an answer variable to store the results of adding/multiplying/etc and supply it as an arugment to void Operation::printOnScreen(int answer), or you need to change the adding/subtracting/etc methods to change the `answer' member variable

    with that diagram, it looks like you are just missing the getAnswer and setAnswer methods.

    that's confusing then; getter methods are supposed to return something, no? :(

    from your first post, your printOnScreen looks fine. when you use it in main you can do something like: o.printOnScreen(o.getAnswer());

    @ajprincess , int Arithmetic::addition(int numberA,int numberB) This is wrong. a.addition(numberA,numberB); It should be int temp; temp =a.addition(numberA,numberB);

    Do you understand that you were not storing the value returnnd by " int Arithmetic::addition(int numberA,int numberB) " in a variable

    I hav already declared answer in my main method. Nw I wrote this answer=a.addition(numberA,numberB) It's correct nw. Isnt t?

    Nope @ajprincess , it should be a.answer=a.addition(numberA,numberB); answer is private member function of Arithmetic

    Got it. It should be answer=a.addition(numberA,numberB); setAnswer(answer); Now it should be fine

    I was busy at another question. If your question is asking for repeting of arithmetic operation then you can add the (Number 1 +Number 2)+number 1

    @ajprincess , why don't you try by yourself?. Learn by trying on your own. You will get the logic. Then try to implement that logic :D
