Question

Computer Science 1 (Help and explain it)

Goal: Calculate the class average for each class and also determine which class has the highest class average.

Create a 2 dimension array 6x30 that represents 6 classes of 30 students each. In the exercise, each of our classes is full and has 30 students.

Fill the array with random numbers in the range of 55- 100

Use embedded for loops so you can determine the class with the highest class average of all the 6 classes

Display each class’s average and then also remind us what the highest average is.

Answer 1

//C++ program

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

int randomNumber(int min , int max){
   return min + rand()%(max - min + 1);
}

int main(){
   int numberOfClasses = 6;
   int numberOfStudents = 30;
   int score[numberOfClasses][numberOfStudents];
   double sum,highest=0,average;
   srand(time(NULL));
  
   for(int i=0;i<numberOfClasses;i++){
       for(int j=0;j<numberOfStudents;j++){
           score[i][j] = randomNumber(55 , 100);
       }
   }
  
   for(int i=0;i<numberOfClasses;i++){
       sum = 0;
       for(int j=0;j<numberOfStudents;j++){
           sum = sum + score[i][j] ;
       }
       average = sum/numberOfStudents;
       cout<<"Average of class-"<<(i+1)<<" : "<<average<<endl;
       if(average>highest)highest = average;
   }
  
   cout<<"\nHighest Average is : "<<highest<<endl;
   return 0;
}
