Question

INSTRUCTIONS 1. Prompt the user for the number of participating units and expected peak demand hours 2. Create two arrays: O A String array called unitstatus, with an array element count equal to the number of participating units o An int array called unitCredit, with an array element count equal to the number of participating units O HINT: make sure you understand the difference between array size (element count) and element index (position) 3. Initialize the arrays, setting each element of the unitStatus array to "ON", and each element of unitCredit to zero o THINK: Think about this for a minute. This requires repeated actions (since you want to do the same thing to each element of each array), so you'll need a loop. What type of loop would work best for this? A while loop or a for loop? 4. For now, work continue to work as if you are solving for a single hour of demand: Shut down the number of units needed to meet demand: To determine how many units to shut down, generate a random integer between 0 and the total number of A/C units . HINT: Be sure that your code allows for 0 units to be needed, as well as the maximum number of units available. For example, if there are 3 units available, then the set of possible values should be 0, 1, 2, and 3. Be sure to test this carefully! O Print the number of units to be shut down in this hour o Mark units as shut down (with credit), starting with the first unit and working sequentially through the array until you have turned off enough units.

Answer 1

The answer will not be the same always because it is generating random integer. Do not panic if you don't get the same answer

#include <iostream>
using namespace std;

int main() {
   //no of participating units participating p
   //no of expected peak hours t
  
   int p,t;
   cin>>p>>t;
   cout<<"Enter the number of units:"<<endl;
   cout<<p<<endl;
   cout<<"Enter the number of hours:"<<endl;
   cout<<t<<endl;
   string Unitstatus[p];
   int Unitcredit[p];
   for(int i=0;i<p;i++)
   {
        Unitstatus[i]="ON";
        Unitcredit[i]=0;
   }
   //for every demand hour
   for(int i=1;i<=t;i++)
   {
        //generate random number between 0 and p
        int num = (rand() %(p - 0 + 1)) + 0;
        cout<<"In hour "<<i<<" we need to shut down "<<num<<" units:"<<endl;
        for(int j=0;j<num;j++)
        {   if(Unitstatus[j]=="OFF")
                Unitstatus[j]="ON";
            else
                Unitstatus[j]="OFF";
            Unitcredit[j]+=1;       
            cout<<"Unit "<<j<<" is "<<Unitstatus[j]<<" with credits: "<<Unitcredit[j]<<endl;
        }
        for(int j=num;j<p;j++)
        {
             cout<<"Unit "<<j<<" is "<<Unitstatus[j]<<" with credits: "<<Unitcredit[j]<<endl;
        }
      
   }
   return 0;
}

This code is in c++ and totally working

Here is java code:

/*package whatever //do not write package name here */

import java.io.*;
import java.util.Scanner;
import java.util.Random;

class GFG {
   public static void main (String[] args) {
       int p,t;
       Scanner sc=new Scanner(System.in);
       System.out.println("Enter the number of units:");
       p = sc.nextInt();
       System.out.println(p);
       System.out.println("Enter the number of hours:");
       t = sc.nextInt();
       System.out.println(t);
       String[] Unitstatus= new String[p];
       int[] Unitcredit= new int[p];
       for(int i=0;i<p;i++)
       {
            Unitstatus[i]="ON";
            Unitcredit[i]=0;
       }
       //for every demand hour
     
   for(int i=1;i<=t;i++)
   {
        //generate random number between 0 and p
        Random rand = new Random();
        int num = rand.nextInt(p+1);
        System.out.println("In hour "+i+" we need to shut down "+num+" units:");
        for(int j=0;j<num;j++)
        {   if(Unitstatus[j]=="OFF")
                Unitstatus[j]="ON";
            else
                Unitstatus[j]="OFF";
            Unitcredit[j]+=1;     
            System.out.println("Unit "+j+" is "+Unitstatus[j]+" with credits: "+Unitcredit[j]);
        }
        for(int j=num;j<p;j++)
        {
             System.out.println("Unit "+j+" is "+Unitstatus[j]+" with credits: "+Unitcredit[j]);
        }
    
   }
      
   }
}
