Answer:

#include <iostream>

using namespace std;

int

main ()

{

 char name[150];

 int rn, sc , x;

 double avg , percentage;

   cout << "Enter stuudent name:";

   cin >> name;

   cout << "Enter number of subjects:";

   cin >> sc;

   cout << "Enter marks for each subject:";

   cin >> x;

   double grades[sc];

       for(int i = 0; i < sc; i++){

           cout << "Enter marks of subject " << (i+1) << ":";

           cin >> grades[i];

       }

       int total = 0;

       for(int i = 0; i < sc; i++){

           total = total + grades[i];

       }

       double total1 = x*sc;

       avg = (double)(total / sc);

       percentage = (double)(total/total1)*100;

       cout << "The total is " << total << endl;

       cout << "The average is " << avg << endl;

       cout << "The percentage is " << percentage << endl;

}
