Question

I need help with a c++ assignment plz comment if you can help

Answer 1

Do you have a specific question?

Answer 2

like we have to create a menu driven quiz that uses +-x÷ in whole numbers have a way to quit give them points out of number correct and fully error trapped

Answer 3

I'm not sure I get the \( + - \times \div \) thing. can you explain how does it work?

Answer 4

like its four diferent quizes using +-x÷

Answer 5

can you give me an example to a question in the quiz?

Answer 6

like 2+2...

Answer 7

Ok, I'm asking that because the exact nature of the questions is essential in order to generate them

Answer 8

oh.. but my nubers are randomily generated 0 -20

Answer 9

Is it always 2 numbers and one operation?

Answer 10

CORRECT! its ment for a second grader

Answer 11

Ok, just one more question, what do you mean by 'fully error trapped'?

Answer 12

that it is fully error trapped like if my quiz menu is only 1 thru 4 then if they enter anything esle other than 1 thru 4 it wont take the answer

Answer 13

Ok I see. So where are you stuck at?

Answer 14

the whole thing lol

Answer 15

Ok, what have you learned so far in C++?

Answer 16

while and do while loops

Answer 17

No classes yet, right? What about functions?

Answer 18

Oh, and for loops, what about those? have you learned?

Answer 19

yea

Answer 20

So you know classes, functions and for loops as well?

Answer 21

YEA

Answer 22

Ok, so let's start with a Screen abstract class, we will make child classes for specific menus, like MainScreen, QuizScreen, StatsScreen and so on
We will redirect any input to those screens and they will decide what is good for them and what's not.
Sounds ok?

Answer 23

OHK

Answer 24

We will have to use virtual methods for this, do you know those?

Answer 25

NOPE

Answer 26

virtual methods are a very powerful tool. they allow you to harness the power of polymorphism in your favor.
For example it will allow us to get input at and pass it to the active Screen without caring what it really is, a MainScreen, QuizScreen or w/e.
It may sound a little complicated at first, but the truth is that it makes things much cleaner and easier to work with

Answer 27

If you're not familiar with polymorphism at all then I can find a short video explaining it =)

Answer 28

ohk

Answer 29

Ok give me a moment

Answer 30

Give this a shot:

Answer 31

Bleh, I see that he gets to virtual functions only in the next video, that continues that one..

Answer 32

that's kinda /extra/
just have 4 functions for add/sub/mult/div
generate 2 random numbers between 0-20 and a third one between 0-3
have the third number decide the operation

Answer 33

thank you makes more sense!
