Design a program for the Hollywood Movie Rating Guide, which can be installed in a kiosk in theaters. Each theater patron enters
ehidna [41]

Answer:

The program in cpp is given below.

#include <iostream>

using namespace std;

int main()

{

   //variables declared to hold sum, count and average of movie ratings

   int sum=0;

   int count=0;

   int rating;

   double avg;

   //audience is prompted to enter ratings

   do{

       std::cout << "Enter the rating (0 to 4): ";

       cin>>rating;

       if(rating>4)

           std::cout << "Invalid rating. Please enter correct rating again." << std::endl;

       if(rating>=0 && rating<=4)

       {

           sum=sum+rating;

           count++;

       }

       if(rating<0)

           break;

   }while(rating>=0);

   //average rating is computed

   avg=sum/count;

   std::cout << "The average rating for the movie is " << avg << std::endl;  

   return 0;

}

OUTPUT

Enter the rating (0 to 4): 1

Enter the rating (0 to 4): 2

Enter the rating (0 to 4): 0

Enter the rating (0 to 4): 5

Invalid rating. Please enter correct rating again.

Enter the rating (0 to 4): 1

Enter the rating (0 to 4): -1

The average rating for the movie is 1

Explanation:

1. Variables are declared to hold the rating, count of rating, sum of all ratings and average of all the user entered ratings.

2. The variables for sum and count are initialized to 0.

3. Inside do-while loop, user is prompted to enter the rating for the movie.

4. In case the user enters a rating which is out of range, the user is prompted again to enter a rating anywhere from 0 to 4.

5. The loop executes until a negative number is entered.

6. Inside the loop, the running total sum of all the valid ratings is computed and the count variable is incremented by 1 for each valid rating.

7. Outside the loop, the average is computed by dividing the total rating by count of ratings.

8. The average rating is then displayed to the console.

9. The program is written in cpp due to simplicity since all the code is written inside main().

To print the last element in the array named ar, you can write :A. System.out.println(ar.length);
timofeeve [1]

Answer:

Option (d) is the correct answer.

Explanation:

An Array is used to store multiple variables in the memory in the continuous memory allocation on which starting index value is starting from 0 and the last index value location is size-1.

In java programming language the array.length is used to tells the size of the array so when the user wants to get the value of the last element, he needs to print the value of (array.length-1) location so the correct statement for the java programming language is to print the last element in the array named ar is--

System.out.println(ar[ar.length-1]);

No option provides the above statement, so option d (None of these) is correct while the reason behind the other option is not correct is as follows--

  • Option a will prints the size of the array.
  • Option b also gives the error because length is an undeclared variable.
  • Option c will give the error of array bound of an exception because it begs the value of the size+1 element of the array.

You are designing an internet router that will need to save it's settings between reboots. Which type of memory should be used t
Phoenix [80]

Answer:

d. Flash

Explanation:

A flash memory can be defined as an electronic non-volatile memory chip (storage medium) that is typically used on computer systems and other digital devices such as routers, USB flash drives, switches, digital cameras, mp3 players etc. A flash memory is an electronically erasable programmable read only memory (EEPROM) and as such data saved (written) on it can be erased electronically. Also, a flash memory do not require a source of power (electricity) to save or retain data through the use of a floating gate MOSFET (FGMOS) or floating gate transistor.

In this scenario, you are designing an internet router that will need to save it's settings between reboots. The type of memory that should be used to save these settings is a flash memory because it does not require power to write or save data.
