[Phil092]

o ! i didnt think i could make it negative ! thank you !! well thats all i have for you right now :p if i have any other questions is it ok to post on here again ? ill fix the code up to make it more 'professional' and ill post the final code soon. thank you kemort once again

i know all the && doesn't look good but i just wanted it to work. i will look at what you just posted so i can learn new ways

You can see there are a number of ways of running through the logic you want and a few && are neither here nor there. As it turns out the if else structure I complained about is not too bad at all. So there you go. I think the thing that fussed me was the whiles and not really understanding what the overall flow was supposed to be.

The net result is though, all the controls structures - loops, whiles, ifs etc are all pretty much interchangeable.

Good luck with it.

hey kemort ! here it is :) i know it probably looks the same but i altered a few things

#include <iostream>
#include <string>
#include <cstdlib>

using namespace std;

void CurrentFriendScore(int&, int);

Hi phil,

It worked - well done.

And I see you have some more snappy questions. Pity you didn't include the snappy answers to get the responses wrong but that's OK, your prof/teacher/tutor might not appreciate humor.

Are you sure -20 is the worst possible score? There are more than 2*'N' answers. But there again I replied with 'n' to every question and got 0.

[Phil092]

o ya thats true. dang.. i already turned it in. wednesday by 5 pm is the deadline for 5% extra credit. its due tomorrow by 5. if i edit it and turn it in again i lose that 5% . but your right. i shouldve included snappy answers tho huh lol

[Phil092]

o wait no -20 is the worst score you can get because the most questions you can answer for points is 2 questions. If you hit no then yes you can only answer 2questions unless its the last if statement which in that case -10 is the worst. do you know what i mean ? or maybe i am misunderstanding you

[48T7M4Gy]

Don't worry Phil, I went back and checked and re-answered everything as no. I thinks its OK.
Take a well earned break.
