class use in a function?

[jrice528]

Ok, i made a psot earlier but my code is alot different and different question so i didnt know where to put it.

My question is thiss... in my calcScore function. This is my requirement:
Design and implement a function double calcScore() that calculates and returns the average of the three scores that remain after dropping the highest and lowest scores a performer received. This function should be called once for each contestant by your function main(), and it should be passed the Stat object that contains the 5 scores from the judges.

I am having trouble of passing the values of score 1-5 into the calcScore function. If i didnt have to use the function it wouldnt be a problem. But I do, and i dont know how to do it.

#include "Stat.h"
#include <iostream>
using namespace std;

void getJudgeData(int &);
double calcScore();

int main()
{
    Stat s;
    int score1 = 0, score2 = 0, score3=0, score4=0, score5=0;
    

	cout << "This program assignment number 4 was created by Jeremy Rice" << endl;
	cout<<  "The Next American Idol!!!"<<endl;
    cout<< "Please enter your scores below!"<<endl; 

cout<< "Enter contestant #1's scores!"<<endl;
cout<<"Judge #1 what is your score"<<endl;
getJudgeData(score1);
s.setNum(score1);
cout<<"Judge #2 what is your score"<<endl;
getJudgeData(score2);
s.setNum(score2);
cout<<"Judge #3 what is your score"<<endl;
getJudgeData(score3);
s.setNum(score3);
cout<<"Judge #4 what is your score"<<endl;
getJudgeData(score4);
s.setNum(score4);
cout<<"Judge #5 what is your score"<<endl;
getJudgeData(score5);
s.setNum(score5);


cout<<"Talent score for contestant #1 is: "<<calcScore()<<endl;


system("pause");
	return 0;
}

void getJudgeData(int &getNum)
{
     Stat s;
    cin>> getNum;
     return;
}

double calcScore()
{
        
       Stat s;
      cout<<(s.getSum()- s.getMin()- s.getMax()) / 3 <<endl;
      
}

Er, sure I have time for one more...

Don't use system("pause"); . Tell your professor it is evil and non-portable and he shouldn't be teaching it. If he gives you a hard time tell him people who know better than he know better. (Yes, I know that sounds non-sequitur, but he should know better either way.)

If you must, use while (cin.get() != '\n'); instead.

Now for your problem.
Make your calcScore() function take an argument: double calcScore( Stat s ); Then you can pass the Stat object you created in main() to the function to calculate the score instead of creating a new, useless Stat object in the function itself. Also, the function should return a value, not print anything.

Hope this helps.

Wow awesome i finally got it, thanks for the help !!! like majorly couldnt of done without help.
I do have one last question. What do I do to start a loop for it all? from the part "is there another contestant?" if i press Y how would i loop that back to the begining?

#include "Stat.h"
#include <iostream>
using namespace std;

void getJudgeData(int &);
double calcScore(Stat s);

int main()
{
    Stat s;
    
    int score1 = 0, score2 = 0, score3=0, score4=0, score5=0;
    int x = 1;
    int winner;


	cout << "This program assignment number 4 was created by Jeremy Rice" << endl;
	cout<<  "The Next American Idol!!!"<<endl;
    cout<< "Please enter your scores below!"<<endl;
     

  cout<< "Enter contestant #"<<x<< " scores!"<<endl;
  cout<<"Judge #1 what is your score: ";
               getJudgeData(score1);
               s.setNum(score1);
  cout<<"Judge #2 what is your score: ";
               getJudgeData(score2);
               s.setNum(score2);
  cout<<"Judge #3 what is your score: ";
               getJudgeData(score3);
               s.setNum(score3);
  cout<<"Judge #4 what is your score: ";
               getJudgeData(score4);
               s.setNum(score4);
  cout<<"Judge #5 what is your score: ";
               getJudgeData(score5);
               s.setNum(score5);
  
  cout<<"Talent score for contestant #"<<x<<" is: ";
                calcScore(s);
                x++;
  cout<<"Is there another contestant? (Y/N)"<<endl;

  
    system("pause");
	return 0;
}



void getJudgeData(int &getNum)
{
     Stat s;
    cin>> getNum;
     return;
}

double calcScore(Stat s)
{
        
cout<<(s.getSum()- s.getMin()- s.getMax()) / 3 <<endl;
      
}

to go back to the beginning, one way is to use a label, like so:

int main()
{
    Stat s;
    
    int score1 = 0, score2 = 0, score3=0, score4=0, score5=0;
    int x = 1;
    int winner;


	cout << "This program assignment number 4 was created by Jeremy Rice" << endl;
	cout<<  "The Next American Idol!!!"<<endl;

enterScores:        //<--------the new stuff
system("cls");      //<------ jaja i know :( system

    cout<< "Please enter your scores below!"<<endl;
     

  cout<< "Enter contestant #"<<x<< " scores!"<<endl;
  cout<<"Judge #1 what is your score: ";
               getJudgeData(score1);
               s.setNum(score1);
  cout<<"Judge #2 what is your score: ";
               getJudgeData(score2);
               s.setNum(score2);
  cout<<"Judge #3 what is your score: ";
               getJudgeData(score3);
               s.setNum(score3);
  cout<<"Judge #4 what is your score: ";
               getJudgeData(score4);
               s.setNum(score4);
  cout<<"Judge #5 what is your score: ";
               getJudgeData(score5);
               s.setNum(score5);
  
  cout<<"Talent score for contestant #"<<x<<" is: ";
                calcScore(s);
                x++;
  cout<<"Is there another contestant? (Y/N)"<<endl;

//more new stuff below

if (cin.get() == 'y' || cin.get() == 'Y'){
         goto enterScores;
         }
  
    system("pause");
	return 0;
}

i havent tried this code but as far as i can see there should be no errors.. if im wrong please someone correct me

o well give it a go hope it helps

I'm not a big fan of 'goto'...

You could try something like:

int main(void)
{
    char Choice = 'Y';
 
    while (Choice == 'y' || Choice == 'Y')
    {
         // do your stuff
        cout << "More?" << endl;
        Choice = cin.get();
    }
}

It will continue your program until something else then 'Y' or 'y' is entered.

oh ja.... seen that used somewhere before. bit more efficient i'd guess. up to you though jrice
