Question

Programming Challenge #10. C++ Early Objects 10ed.

A talent competition has five judges, each of whom awards a score between 0 and 10 to each performer. Fractional scores, such as 8.3, are allowed. A performer's final score is determined by dropping the highest and lowest score received, then averaging

#include <iostream>
#include <iomanip>
using namespace std;

// Function prototypes
double getJudgeData();  
double calcScore(double, double, double, double, double);                       
double findLowest(double, double, double, double, double);                      
double findHighest(double, double, double, double, double);
                
int main()
{
        double score1, score2, score3, score4, score5,   // 5 judge's scores
          finalScore;
   
        // Inform the user what the program does
        cout << "After you enter 5 judge scores for this contestant, \n"
        << "this program will drop the highest and lowest score \n"
        << "and then average the remaining three scores.\n\n";
        

        return 0;
}// end of main function

the three remaining scores. Write a program that uses these rules to calculate and display a contestant's score.
