Thread: Pass by reference

Ok, I am really stuck, and need major help. Ths assignment i am working on is as follows:

Its american idol. Design a function getJudgeData that asks the user for a judge's score, stores it in a reference parameter variable, and validates it. This function should be called by your function main() once for each of the 5 judges.

I have my class built i am just working on the main.cpp file...

I would REALLY appiciated ANY help. I am having trouble passing it by reference by using the Class Stat. I cant get the getJudgeData to put the data and store it into the class. Does anybody have ANY suggestions PLEASE? I can post the class if you need to see it I want to take the s.getNum(); and store the scores into there.

Code:

#include <iostream>
#include "Stat.h"

using namespace std;

void getJudgeData(int &);

double calcScore();


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

	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<<"Judge #1 what is your score"<<endl;
getJudgeData(score1);
cout<<"Judge #2 what is your score"<<endl;
getJudgeData(score2);
cout<<"Judge #3 what is your score"<<endl;
getJudgeData(score3);
cout<<"Judge #4 what is your score"<<endl;
getJudgeData(score4);
cout<<"Judge #5 what is your score"<<endl;
getJudgeData(score5);



system("pause");
	return 0;
}

void getJudgeData(int &score)
{
     Stat s;
    s.getNum("");
    
    
}

// The average is the min and max subtracted
// the remaining three numbers are calculated for average
/*double calcScore()
{
       Stat s;
       int average = 0;
       average(s.getSum - s.getMin - s.getMax)/3;
}
*/

Yeah the double calc function i am not working on atthe moment, mainly on the getJudgeData heres the stat.h file.

What i want to do is use the stat class to keep track of the 5 judges scores. I cant modify my stat class any further, he has a copy now and said if its modified i get a 0... lol gay.

Code:

// FILENAME:        Stat.h
//
// CLASS PROVIDED:  Stat

#ifndef STAT_H
#define STAT_H

#include <string>

using namespace std;

class Stat {

  // ATTRIBUTES /////////////////////////////////////////////////////////

  private:
     int      thenum; // last integer entered
     unsigned count;  // number of integers entered so far
     int      sum;    // sum of all integers entered so far
     long     prod;   // product of all integers entered so far
     int      min;    // minimum of all integers entered so far
     int      max;    // maximum of all integers entered so far
     unsigned evens;  // count of evens of all integers entered so far
     unsigned odds;   // count of odds  of all integers entered so far

  // OPERATIONS /////////////////////////////////////////////////////////

  public:
     Stat( );
  // - default constructor
     void setNum ( int newNum );
  // - sets the last integer entered to newNum
     void getNum ( string prompt );
  // - displays prompt and reads in another integer
     void reset (  );
  // - resets all statistical values
     int getNum (  );
  // - returns the last integer entered
     unsigned getCount (  );
  // - returns the number of integers entered so far
     int getSum (  );
  // - returns the sum of all integers entered so far
     long getProd (  );
  // - returns the product of all integers entered so far
     int getMin (  );
  // - returns the minimum of all integers entered so far
     int getMax (  );
  // - returns the maximum of all integers entered so far
     float getAverage (  );
  // - returns the average of all integers entered so far
     unsigned getEvens (  );
  // - returns the number of even integers entered so far
     unsigned getOdds (  );
  // - returns the number of odd integers entered so far

};

#endif

these are the requirements of the getJudgeData function:

Design and implement a function void getJudgeData() that asks the user for a judge's score, stores it in a reference parameter variable, and validates it. This function should be called by your function main() once for each of the 5 judges.

Use the Stat class to keep track of the five judges' scores. Do NOT modify the Stat class --- you should be able to use it as is!
