Answer:

Option a is the correct answer for the above question

Explanation:

The above question code has one for-loop which runs two times only for the value of number=20.
It is because when the if-condition will true then the loop will be exit because it holds the break statement which exits the for-loop when the if-condition will be true.
So when the first time 20 will divide by 3 then if-condition will fail, but when the 20 will be divide by the 5, then the if condition will be true and the 5 will be printed as output.
Then the second if-condition will false because it will be true for the 20 value of i.
Hence option a is the correct answer while the other is not correct because others will not hold the output of this code.

Ld' is the instruction with the longest latency on the CPU from Section 4.4 (in RISC-V text). If we modified ld and sd so that t

antiseptic1488 [7]

Answer:

See explaination

Explanation:

The primary factors that influence the program's speed on a new CPU are given as:-

CPU Clock speed where the speed of the process instructions is being measured.

Multi-core which is when the transistors work faster than respective CPU.

Cache which helps to note that the transition of data is smooth and fast.

So, there are two CPUs suppose the old one as 'A' and the modified one as 'B'.

'A' has following features---

It takes more time to execute program as it has more clock cycle time or we can say it has low clocking rate or low speed in terms of MHz or GHz. Clock rate is the inverse of Clock Cycle Time. When you will increase the clocking rate of CPU, it will get faster and then Clock Cycle Time will get reduced.

It has less instructions provided.

'B' has following features----

It takes less time to execute program as it has less clock cycle time or we can say it has high clocking rate or high speed in terms of MHz or GHz.

It has more instructions provided.

The performance of CPU depends upon 2 factors:

The number and types of instructions that are executed by the CPU

How fast the CPU can execute those instructions?

So, overall CPU B is better as it has less execution time than CPU A but the performance will always depend upon the number and type of instructions executed by the CPU so it may vary.

Please refer to attachment for instructions and formulas.

Ann [662]

Due to it's typically massive size, WAN's are almost always slower then a LAN. The further the distance, the slower the network. One of the big disadvantages to having a WAN is the cost it can incur. Having a private WAN can be expensive.

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().
