Write a program that asks the user for the name of a text file. The program should display the first 10 lines of the file on the screen. If the file has fewer than 10 lines, the entire file should be displayed along with a message indicating the entire file has been displayed.

Answers

Answer 1

Answer:

Written in Python

filenm = input("File name: ")

myfile = open(filenm+".txt")

for i in range(10):

     line = myfile.readline()

     print(line)

print("End of file")

Explanation:

This line prompts user for file name

filenm = input("File name: ")

This line creates an instance of the file

myfile = open(filenm+".txt")

This line iterates through the 10 lines

for i in range(10):

This line reads the line

     line = myfile.readline()

This line prints each line

     print(line)

This line prints a message indicating that all possible lines have been printed

print("End of file")

Display all the lines in unixPasswd that contain at least 10 consecutive lowercase letters. How many names are there in total that meets this criteria?

Answers

Answer and Explanation:

To display 10 consecutive lower case letters in Unix, we make use of the commands below. The first command finds the letters in the file and the second command counts them line by line.

$ grep '[a-z]\{10,\}' /unixPasswd/passwd

# this command displays lines with at least 10 consecutive lowercase letters or more than 10 consecutive lowercase letters

$ grep '[a-z]\{10,\}' /unixPasswd/passwd | wc -l

# this command counts the number of lines that has at least 10 consecutive lower case letters or more than 10 consecutive lowercase letters

Note: the unixPasswd is a file in passwd file. The # is used when we want to add comments, is optional here. The $ is a prompt on the terminal that begins a new command.

One time tell me you need me tonight
To make it easy, you lie

The problem lies within your if statement. You're using a single equals sign when you should be using two.

if (operation == 1)

Two equal signs is a comparison operator. It checks to see if one value equals another value. In your case, its checking if operation equals 1. But, this only solves half the problem. Operation is a string and you need to compare it to a string.

if (operation == "1")

Assume a large shared LLC that is tiled and distributed on the chip. Assume that the OS page size is 16KB. The entire LLC has a size of 32 MB, uses 64-byte blocks, and is 32-way set-associative. What is the maximum number of tiles such that the OS has full flexibility in placing a page in a tile of its choosing?

Answers

Answer:

19 - 22 bits ( maximum number of tiles )

Explanation:

from the given data :

There is 60 k sets ( 6 blocks offset bits , 16 index bits and 18 tag bits )Address has 13-bit page offset and 27 page number bits14-22 bits are used for page number and index bits

therefore any tour of these bits can be used to designate/assign tile number

so the maximum number of tiles such that the OS has full flexibility in placing a page in a tile of its choosing can be between 19 -22 bits

Write a program that will add the content of two counters every 45 seconds and place the result in an integer register.

Answers

Answer:

Explanation:

The following code is written in Java and runs a thread every 45 seconds that adds the two counters together and saves them in an integer variable called register. Then prints the variable. If this code runs 5 times it automatically breaks the loop. This can be changed or removed by removing the breakLoopCounter variable.

 public static void add_Counters(int counterOne, int counterTwo) {

       int register = 0;

       int breakLoopCounter = 0;

       try {

           while (true) {

               register += counterOne + counterTwo;

               System.out.println(register);

               Thread.sleep(45000);

               breakLoopCounter += 1;

               if (breakLoopCounter == 5) {

Answers

Answer:

<textarea wrap="hard" cols="30" rows="5"></textarea>

Explanation:

A textarea element or tag is a form tag element of a HTML file. It is used to ask for input value from a user in a webpage. The textarea tag has an opening and a closing tag.

The 'cols' attribute is used to set the column length while the 'rows' attribute sets the row length of the textarea element. The 'wrap' attribute has three options namely; soft, hard, and off. 'soft' adds the textarea wrapping, 'hard' sets off the box wrapping but only wraps each line, while the 'off' option removes all wrapping in the tag.

Solve (2011) uses the hammer and an example of his concept polypotency; what are some other examples of familiar artifacts?

Answers

Explanation:

1- The cell phone is a modern technology that has been developing and gaining new features in addition to being just a device for making phone calls. Currently cell phones perform the same tasks as computers, making it possible to exchange information from the internet, share media, etc.

The development of smartphones will still be significant and will impact even more on the lives of all users, as an essential device for communication at work, and through software developed for cell phones that facilitate human life, such as through the possibility of making purchases , order a taxi, carry out bank transactions, etc.

2- A management information system is a technology aimed at organizations, in order to assist a manager in the decision-making process.

An MIS is an intelligent system that uses a large volume of data and information to generate information and solutions so that a manager has a greater chance of analyzing a scenario in the organization, and makes a more effective decision for the company.

The system is derived from procedures and interaction between people, which generates constant learning and improvement focused on organizational decisions.

MIS was created to assist current organizational management, whose processes derive from a large amount of data and information, in addition to the high competitiveness in the market, which requires decisions to be made quickly, effectively and at the lowest cost.

3- The cell phone and the computer are examples of polypotent technologies, that is, those that are used for purposes greater than those for which they were created, for example, the computer was created to compute data, and the cell phone to make telephone calls, but currently perform functions of being media sharing, communication and leisure equipment.
