Write a C program to create a series of processes, as shown below in the diagram.

P |------ ---- > c1 |------------>c2

                             |------- ------>c3 ---------->c4

In other words, the parent process p creates process c1, c1 creates c2 and c3, and c3 creates c4.

A sample run of the program shows

Your program should output something similar to what is shown above. You could optionally use wait/waitpid/sleep/exit in your program.

Comment your code to show where you created p, c1, c2, c3, c4, etc.

1.For Python Which statement(s) are true regarding private class variables?

private variables can be accessible inside the class.

private variables can be accessible outside the class.

private variable values can be changed directly outside of the class

private variables can be changed outside the class through set methods.

2.

In the following code,

def A:
def __init__(self):
     __a = 1
     self.__b = 1
     self.c = 1
     __d__ = 1

# Other methods omitted

Which of the following is a private data field?

Group of answer choices

__a

__b

c

__d__

3.

Analyze the following code and choose the more accurate statement.

class A:
     def __init__(self, s):
         self.s = s

     def print(self):
         print(s)

a = A("Welcome")
a.print()

Group of answer choices

The program has an error because class A does not have a constructor.

The program has an error because class A should have a print method with signature print(self, s).

The program has an error because class A should have a print method with signature print(s).

The program would run if you change print(s) to print(self.s).

4.

Replace <missing value> and <missing code> with your answers. Your code should compute the factorial of n. For example, if n = 5, your code should compute the following 5 * 4 * 3 * 2 * 1 (which is 120).

public static void main(String[] args)
{

Scanner scanner = new Scanner(System.in);
int n = scanner.nextInt();

int factorial = <missing value>;

<missing code>

System.out.println("factorial = " + factorial);

Let A and B be two stations attempting to transmit on an Ethernet. Each has a steady queue of frames ready to send; A’s frames will be numbered ?1, ?2 and so on, and B’s similarly. Let ? = 51.2 ???? be the exponential backoff base unit. Suppose A and B simultaneously attempt to send frame 1, collide, and happen to choose backoff times of 0 × ? and 1 × ?, respectively. As a result, Station A transmits ?1 while Station B waits. At the end of this transmission, B will attempt to retransmit ?1 while A will attempt to transmit ?2. These first attempts will collide, but now A backs off for either 0 × ? or 1 × ? (with equal probability), while B backs off for time equal to one of 0 × ?, 1 × ?, 2 × ? and 3× ? (with equal probability).

What is the probability that A wins all the ? backoff races. (? is a given constant)

The following shows the French translation for some colours: English French red rouge orange orange yellow jaune green vert blue bleu Create a program ColourTranslator that displays the French translation of the English colour obtained from the user. E.g.: System: Enter a colour in English: User: red System: The French word for red is rouge. Include a default case that handles input that is not on the list. e.g. System: Enter a colour in English User: purple System: Sorry, purple is not in the list.

Program 3: Give a baby $5,000! Did you know that, over the last century, the stock market has returned an average of 10%? You may not care, but you’d better pay attention to this one. If you were to give a newborn baby $5000, put that money in the stock market and NOT add any additional money per year, that money would grow to over $2.9 million by the time that baby is ready for retirement (67 years)! Don’t believe us? Check out the compound interest calculator from MoneyChimp and plug in the numbers!

To keep things simple, we’ll calculate interest in a simple way. You take the original amount (called the principle) and add back in a percentage rate of growth (called the interest rate) at the end of the year. For example, if we had $1,000 as our principle and had a 10% rate of growth, the next year we would have $1,100. The year after that, we would have $1,210 (or $1,100 plus 10% of $1,100). However, we usually add in additional money each year which, for simplicity, is included before calculating the interest.

Your task is to design (pseudocode) and implement (source) for a program that 1) reads in the principle, additional annual money, years to grow, and interest rate from the user, and 2) print out how much money they have each year. Task 3: think about when you earn the most money!

Lesson learned: whether it’s your code or your money, save early and save often…

Sample run 1:

Enter the principle: 2000

Enter the annual addition: 300

Enter the number of years to grow: 10

Enter the interest rate as a percentage: 10

Year 0: $2000

Year 1: $2530

Year 2: $3113

Year 3: $3754.3

Year 4: $4459.73

Year 7: $7028.2

Year 8: $8061.02

Year 9: $9197.12

Sample run 2 (yeah, that’s $9.4MM):

Enter the principle: 5000

Enter the annual addition: 1000

Enter the number of years to grow: 67

Enter the interest rate as a percentage: 10

Year 0: $5000
