assume a program in unix that have a multiple system calls

how to show the list of system calls used in the program?

Write a program that repeatedly generates a random integer in the range [1, 100], one integer at a time, and displays the generated numbers on the screen according to the following rules:

• If the second number generated is greater than the first number, they are displayed on the screen in the order of their input and while the next random number generated is greater than the previous one, the random number is displayed on the screen and the program continues. As soon as the number generated is less than or equal to the previous one, the program terminates. For example, if the first 6 random numbers generated are 1, 5, 32, 68, 89, and 11, the output of the program would be:

1

5

32

68

89

• If the second number generated is less than the first number, they are displayed on the screen in the order of their input and while the next random number generated is less than the previous one, the random number is displayed on the screen and the program continues. As soon as the number generated is greater than or equal to the previous one, the program terminates. For example, if the first 3 random numbers generated are 45, 31, and 31, the output of the program would be:

45

31

• If the second number generated is equal to the first number, the program terminates and no message is displayed on the screen.

IN C++ ONLY PLEASE

Write a program fragment (not a complete program) which will perform the following task:

The int variable m currently contains the number of minutes a basketball player played in their last game.

Use an IF statement(s) to print out an appropriate message based on the following:

If m is from 35 to 48, print the message "very tired"

If m is from 10 to 34, print the message "little tired"

If m is from 1 to 9, print the message "played at least"

If m is 0, print the message "bench warmer"

If m is not in the range from 0 to 48, print the message "invalid data"

Language: Python

Function name : sort_by_rating
Parameters : file (.csv file), category (string), order (boolean)
Returns: None
Description : You want to see what order the items of a particular category in your file would be in if you sorted them by rating. Given a file, a category of clothing, and an order boolean (True for ascending order, False for descending order), create a function that writes a file called “sorted_items.csv” that includes all of the items in the specified category in sorted order by ranking.
The format of the file should look like this:

(NOTE: there will be a header row at the top of each .csv file)

Note: If your input file contains no items in the specified category, your “sorted_items.csv” file should still be created and have the header row. Also, your written files should end in a new line character
Hint : You can use the built-in Python .sort() method on a list of tuples. The tuples will get sorted by the first item in each tuple. Example:
>>> list_of_tups = [(5, "cats"), (6, "kittens"), (1, "lizards")] >>> list_of_tups.sort()
>>> print(list_of_tups)
[(1, 'lizards'), (5, 'cats'), (6, 'kittens')]

Test cases:

>>> sort_by_rating("uniqlo.csv","tops",True)

Provide the basic goal of Software Architectural evolution in the software design process. Also, discuss three stages of software development stages where architectural evaluation can be applied.

Suppose both the sender and receiver are in the same local area network. If the sender has the receiver's IP address only, but not the MAC address, how does ARP (Address Resolution Protocol) find out the receiver's MAC address?

The following sequence of operations essentially leaves a queue unchanged.

Group of answer choices

enqueue followed by dequeue

dequeue followed by enqueue

two enqueues followed by two dequeues

two isEmptys followed by two isFulls

A standard linked list provides a good implementation of a "Deque".

Group of answer choices

True

False

The main thread of a Java program cannot generate additional threads.

Group of answer choices

True

False

The text's link-based queue is being used and holds an empty queue. We can say:

Group of answer choices

at this point in time an invocation of the enqueue method would throw an exception.

at this point in time an invocation of the dequeue method would throw an exception.

the value of front is -1.

C++ program that runs on Visual Basic that computes the total cost of books you want to order from an online bookstore. It does so by first asking how many books are in your shopping cart and then based on that number, it repeatedly asks you to enter the cost of each item. It then calls two functions: one for computing the taxes and another for computing the delivery charges. The function which computes delivery charges works as follows: It adds a 5% delivery charge for standard delivery if the total is below $1,000, and an additional 10% charge if you want an expedited next day delivery. The tax and delivery charges are added to the bill and the total cost is displayed.
