Question

 Rewrite the solution to the Star Search problem, see page 370 Programming Challenges,  to use a dynamic array.  Read the number of judges from the standard input device. Make sure the user enter numeric input;  make sure that number of judges is greater than 0.  Create  a dynamic array, using the new operator, to store the judges' scores.   here is my solution to the Star Search.  #include  #include  using namespace std;   void getJudgeData(double &x); double findLowest(double, double, double, double, double); double findHighest(double, double, double, double, double); void calcAverage(double, double, double, double, double);  void main()  {                    double score1, score2, score3, score4, score5;         cout << "Score collection of all the five judges  ";           getJudgeData(score1);         getJudgeData(score2);         getJudgeData(score3);         getJudgeData(score4);         getJudgeData(score5);          calcAverage(score1, score2, score3, score4, score5);          system("pause");  }  void getJudgeData(double &x) {         do         {                 cout << "Enter score of judge : ";                 cin >> x;                  if (x < 0 || x > 10 || cin.fail())                 {                         cout << "Error please enter valid input! " << endl;                         cin.clear();                         cin.ignore();                 }          } while (x < 0 || x > 10 || cin.fail()); }  double findLowest(double a, double b, double c, double d, double e) {          double lowest;         lowest = a;         if (blargest)                 largest = b;         if (c>largest)                 largest = c;         if (d>largest)                 largest = d;         if (e>largest)                 largest = e;         return largest; }  void calcAverage(double a, double b, double c, double d, double e) {         double lowest;         double highest;         double sum;          lowest = findLowest(a, b, c, d, e);         highest = findHighest(a, b, c, d, e);          sum = a + b + c + d + e;         sum = sum - highest;         sum = sum - lowest;         sum = sum / 3;                  cout << "Highest score of five numbers: " << highest << endl;         cout << "Lowest score of five numbers: " << lowest << endl;         cout << " After droping highest and lowest scores which you recieved, ";         cout << "Your average score is " << sum << endl; } 

Explanation / Answer

Please find the solution with dynamic array below:

#include<iostream>
#include<cstdlib>

using namespace std;

int numJudges;

void getJudgeData(double *);
double findLowest(double *);
double findHighest(double *);
double calcSum(double *);
void calcAverage(double *);

int main()

{
// take integer input from user for number of judges
cout<<"Please enter number of judges : ";
cin >> numJudges;

if(numJudges<=0){
cout<< "Invalid number of judges entered. Number of judges should be > 0.";
return 1;
}

double *scores = new double[numJudges];
cout << "Score collection of all "<<numJudges<<" judges ";

getJudgeData(scores);

calcAverage(scores);

system("pause");

}

void getJudgeData(double *a)
{
double x;
for (int i =0;i<numJudges;i++)
{
cout << "Enter score of judge # "<<(i+1)<<": ";
cin >> x;

if (x < 0 || x > 10 || cin.fail())
{
cout << "Error please enter valid input! " << endl;
cin.clear();
cin.ignore();
i--;
}else{
a[i]=x;
}
}
}

double findLowest(double *a)
{

double lowest=11;
for (int i =0;i<numJudges;i++)
{
if (a[i]<lowest)
lowest = a[i];
}
return lowest;
}

double findHighest(double *a)
{

double highest=0;
for (int i =0;i<numJudges;i++)
{
if (a[i]>highest)
highest = a[i];
}
return highest;
}

double calcSum(double *a){
double total=0;
for (int i =0;i<numJudges;i++)
{
total += a[i];
}
return total;
}

void calcAverage(double *scores)
{
double lowest=findLowest(scores);
double highest= findHighest(scores);
double sum= calcSum(scores);

double average = sum/numJudges;

cout << "Highest score of five numbers: " << highest << endl;
cout << "Lowest score of five numbers: " << lowest << endl;
cout << "Your average score is (including highest and lowest scores which you received) :" << average << endl;
}
