1.9 HW7 This homework assignment gives you the opportunity to practice functions, functions that call other functions, reference variables, logical statements (what is meant by logical statement is a statement such as if, if/else if, switch), and input validation, HW7 (Graded out of 100) A talent competition has 5 judges, each of whom awards a score between 0 and 10 for 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 the three remaining scores. Write a program that uses this method to calculate a contestant's score 1. Additional requirements - Make sure you meet all the requirements to avoid losing points • Follow the requirements in the Homework Notes" • You are required to implement your program with the functions below. You may implement additional functions to make your program more modular if you wish. getJudgeData: prompts the user to enter the 5 judge scores, stores them in reference parameter variables, and performs input validation for each score. A score is invalid if it is lower than 0 or higher than 10. If any of the inputs is invalid, the function displays an error message, and an exit statement is executed with the failure code EXIT_FAILURE. The function is passed 5 score variables of type double by reference and returns void. The function should be called by the main function once. o calcScore this function calculates and displays the average of the 3 scores that remain after dropping the highest and lowest scores the performer received. The average value should be displayed with one digit after the decimal point. This function should be called just once by the main function and should be passed the 5 scores by value. The function returns void. If your code does not conform to the above function return types and parameter lists, you will fail the unit tests. 2. Hint for implementation

Answer 1

#include <bits/stdc++.h>
using namespace std;
void calcSCore(double scores[], int n)
{
   double min=scores[0];
   double max=scores[0];
   double sum=0.0;
   for (int i = 0; i < n; ++i)
   {
       sum+=scores[i];
       if (max<scores[i])
       {
           max=scores[i];
       }
       if (min>scores[i])
       {
           min=scores[i];
       }
   }
   sum=sum-(min+max);
   cout<<"After dropping the lowest and highest score, average score is "<<sum/3<<endl;
   cout<<"Normal Termination exiting"<<endl;
}
void getJudgeData()
{
   double scores[5];
   for (int i = 0; i < 5; ++i)
   {
       cout<<"Enter a judge's score : ";
       cin>>scores[i];
       if (scores[i]<0||scores[i]>10)
       {
           cout<<"The score must be between 0.0 and 10.0, exiting"<<endl;
           exit(EXIT_FAILURE);
       }
   }
   calcSCore(scores,5);
}
int main(int argc, char const *argv[])
{
   getJudgeData();
   return 0;
}

With randomly generated values -

#include <bits/stdc++.h>
using namespace std;
double randomFunction(double start, double end)
{
double f = (double)rand() / RAND_MAX;
return start + f * (end - start);
}
void calcSCore(double scores[], int n)
{
   double min=scores[0];
   double max=scores[0];
   double sum=0.0;
   for (int i = 0; i < n; ++i)
   {
       sum+=scores[i];
       if (max<scores[i])
       {
           max=scores[i];
       }
       if (min>scores[i])
       {
           min=scores[i];
       }
   }
   sum=sum-(min+max);
   cout<<"After dropping the lowest and highest score, average score is "<<sum/3<<endl;
   cout<<"Normal Termination exiting"<<endl;
}
void getJudgeData()
{
   double scores[5];
   for (int i = 0; i < 5; ++i)
   {
       //cout<<"Enter a judge's score : ";
       //cin>>scores[i];
       scores[i]=randomFunction(0,10);
       cout<<"Judge's score is "<<scores[i]<<endl;
       if (scores[i]<0||scores[i]>10)
       {
           cout<<"The score must be between 0.0 and 10.0, exiting"<<endl;
           exit(EXIT_FAILURE);
       }
   }
   calcSCore(scores,5);
}
int main(int argc, char const *argv[])
{
   getJudgeData();
   return 0;
}
