Write a loop that reads strings from standard input where the string is either "land", "air", or "water". The loop terminates wh

____ [38]

Answer:

count_land = count_air = count_water = 0

while True:

s = input("Enter a string: ")

if s == "xxxxx":

break

else:

if s == "land":

count_land += 1

elif s == "air":

count_air += 1

elif s == "water":

count_water += 1

print("land: " + str(count_land))

print("air: " + str(count_air))

print("water: " + str(count_water))

Explanation:

*The code is in Python

Initialize the variables

Create a while loop that iterates until a specific condition is met. Inside the loop, ask the user to enter the string. If it is "xxxxx", stop the loop. Otherwise, check if it is "land", "air", or "water". If it is one of the given strings, increment its counter by 1

When the loop is done, print the number of strings entered in the required format

5.14 Describe how the compare and swap() instruction can be used to provide mutual exclusion that satisfies the bounded-waiting

Naddik [55]

Answer:

Explained below

Explanation:

Compare and Swap(C&S) is simply an atomic operation whereby the compare and swap operations are automatically executed.

Now compare and Swap basically needs 3 arguments namely:

- 2 old values which we will label X and Y

- 1 new value which is written in X that we will call Z

Thus, we now have; C & S = {X, Y, Z}

To explain this well, let X be a variable where X has a value of 7.

Now, if a programmer gives a program me that X be multiplied by 2,then what C&S operation will do is;

I) Y = X where Y is a new variable.

II) Result = C&S(X, Y, X*7)

Variable X is global and this means that mere than one process and more than 1 thread can see the variable X.

Now, if a process named P1 wants multiply the variable X by 7 using C&S operation, it will first make a local copy of variable X (which in this case is now the new variable Y). After that it will atomically compare X & Y and if they are equal, it will replace X with 10X.

However, if they are not equal, P1 will re-read value of X into Y and carry of C&S instruction again.
