Create a class ""student"" that will hold an array of grades and has a method to calculate the average. it would also have a method to return any particular grade number (1-14).

#include <iostream>

#include<time.h>

using namespace std;

class Student

{

   public :

   int grades[20]; //array of grades

   double average(int arr[],int n) //method to calculate average of array of grades passed

   {

       int sum=0;

       for(int i=0;i<n;i++)  //loop to calculate sum of all grades

           sum=sum+arr[i];

       return sum/n;   //average is sum of items/number of items

   }

   int get_grade() //method to return grade number(1-14)

   {

       srand(time(NULL));  //method to generate different random number each time

       int num = rand() % 14 + 1;  //method to generate random number b/w 1-14

       return num;

   }

};

int main()

{

   Student s;

   int grade[]={5,3,9,8,10};

   cout<<"Average is : "<<s.average(grade,5);

   return 0;

}

OUTPUT :

Average is : 7

Explanation:

A class Student is created in which a method named average is there to calculate average of the grades passed and a method to generate a grade number b/w 1-14.
