Answer:
#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.
