Programming using C++

Also include comments in each step to explain what it does in the program. The program should display similarly to Figure 1 and Figure 2.

Solution

#include <iostream>
#include <stdlib.h>
using namespace std;

int main()
{
   int i,n,countmore50,countless50;
   float average,highest,lowest;
  
   average = 0;
   countmore50 = 0;
   countless50 = 0;
  
   highest =0;
   lowest =100;
  
   cout<<\"\ \\t\\t\\tNancy\'s Statistics Generator\";
   cout<<\"\ \\t\\t\\t-----------------------------\";
  
   cout<<\"\ Hello Professor, how many grades do I need to analyse this time>\";
   cin>>n;
  
   if(n == 0)
   {
   cout<<\"\ \ Guess you changed your mind\";
   cout<<\"\ Ending the program now\";
   exit(0);
   }
  
   float grades[n];
  
   cout<<\"\ \ Okay, I am ready. Start..... \";
   for(i=0;i<n;i++)
   cin>>grades[i];
  
   cout<<\"\ Here are the requested stats for the \"<<n<<\" grades\";
   for(i=0;i<n;i++) //input grades
   {
       average = average + grades[i];
      
       if(highest<grades[i])   
       highest = grades[i];
      
       if(lowest > grades[i])
       lowest = grades[i];
      
       if(grades[i]<50)
       countless50++;
      
       if(grades[i]>=50)
       countmore50++;
      
      
      
      
   }
   //display stats
   cout<<\"\ The class average is \"<<average/n;
   cout<<\"\ The highest grade is \"<<highest;
   cout<<\"\ The lowest grade is \"<<lowest;
   cout<<\"\ The number of students who scored less than 50 is \"<<countless50;
   cout<<\"\ The number of students who scored 50 or better is \"<<countmore50;
  
   cout<<\"\ \ Thats it!!!\";
  
   return 0;
}
