Question

1. Write a program in C++ that inputs an unknown number of test scores (assume that there is a maximum of 150 scores). Ask the user how many scores that they will be entering. The program should have at least 3 functions. Make sure the functions perform the following:
   1. Calculate the average score
   2. Find the highest score
   3. Find the lowest score
   4. Sort the list from highest to lowest

Output the number of scores, the average, the sorted list, the highest, and the lowest. Use the following data to enter: 10

100 90 89 98 50 66 89 80 92 99

Answer 1

Code Screenshot :

Executable Code:

#include <iostream>
using namespace std;
void average(int arr[],int n){
   double avg ,sum = 0;
   for (int i = 0; i < n; i++)
   {
       sum+=arr[i];
   }
   cout<<"\nAverage: "<<sum/n;
}
void highest(int arr[],int n){
   int max = arr[0];
   for (int i = 0; i < n; i++)
   {
       if (max < arr[i])
           max = arr[i];
   }
   cout<<"\nHighest Marks: "<<max;
}
void lowest(int arr[],int n){
   int i;
   int min = arr[0];
   for (i = 0; i < n; i++)
   {
       if (min > arr[i])
           min = arr[i];
   }
   cout<<"\nLowest Marks: "<<min;
}
void sort(int arr[],int n){
   int i,temp,j;
       for(i=0;i<n;i++)
       {      
           for(j=i+1;j<n;j++)
           {
               if(arr[i]<arr[j])
               {
                   temp =arr[i];
                   arr[i]=arr[j];
                   arr[j]=temp;
               }
           }
       }
       cout<<"\nMarks after sorting :"<<endl;
       for(i=0;i<n;i++)
           cout<<arr[i]<<"\n";
       cout<<endl;
}
int main()
{
   int marks[150],size;
   cout<<"Please enter the number of test scores: ";
   cin>>size;
   for(int i=0 ;i<size; i++){
       cin>>marks[i];
   }
   highest(marks,size);
   lowest(marks,size);
   sort(marks,size);
   average(marks,size);
   return 0;
}
