Introduction

This lab will focus on creating a Movie class conforming to the diagram above. From this class Movie objects can be instantiated and used in a running program. I have provided a mostly completely driver, you will need to add a few lines of code where specified.

What you need to do

  •  Declare you instance variables at the top of the class.

  •  Write a specifying constructor. No default constructor is required.

  •  Write getName and setName. There are no restrictions on the setting the name.

  •  Write getMinutes and setMinutes. When setting minutes, it is not allowed to be negative.

  •  Write getTomatoScore and setTomatoScore. When setting tomato score, score is not allowed

    to be negative or over 100.

  •  Write isFresh. A score is considered fresh if it is 60 or above. It is rotten otherwise.

  •  Write display. Print out the name, the total minutes, and if the movie is “Fresh” or “Rotten”.

    Remember, you have method which tells you this now.

  •  The driver is mostly complete. I placed one TODO, add a new movie of your choice to the array

    that stores movies (called myCollection) in the driver.

Your output should match the output below plus the one movie you add to it. Pay attention to how objects are accessed in the driver. See your TA when your output is correct.

Output:
Here are all the movies in my collection of movies.

Movie: Batman The Dark Knight Length: 2hrs 32min.
Tomato Meter: Fresh

Movie: Avengers: Endgame Length: 3hrs 2min. Tomato Meter: Fresh

Movie: The GodFather Length: 2hrs 58min. Tomato Meter: Fresh

Movie: Suicide Squad Length: 2hrs 17min. Tomato Meter: Rotten

//The movie you add will print out here.

_______________________________________________ Here are the Fresh movies.

Batman The Dark Knight is fresh. Avengers: Endgame is fresh.
The GodFather is fresh.

Here are the Rotten movies. Suicide Squad is rotten.

//The movie you add will print out here, it’s score will determine if fresh or not.

_______________________________________________
The movie Harry Potter and the Prisoner of Azkaban was created.

Is Harry Potter and the Prisoner of Azkaban a long movie? Yes, it is a bit long.

Can I set the minutes of Harry Potter and the Prisoner of Azkaban to a negative number?
It did NOT work. Negative runtimes are not allowed.

Can I set tomato score of Harry Potter and the Prisoner of Azkaban to a negative number?
It did NOT work. Negative scores are not allowed.

Can I set tomato score of Harry Potter and the Prisoner of Azkaban to a number greater than 100?
It did NOT work. Still the best Harry Potter movie out all the movies though.

In java

Modify your finished guessNumber.java program to include a random number generator to generate the guessed number (from 1 to 10). use the Random class to generate a random number between a range of integers. In your program include an if … then statement to check if the number you entered is bigger or smaller than the guessed number, and display a message. Also included is a counter to keep track on how many times the user has guessed, and display it at then end.

Below is the java code that needs to be modified:

/* Week3 in-class exercise
Name: numberGuess.java
Author: Your Name
Date:

*/

// need the Scanner class to get user input
import java.util.Scanner;

public class numberGuess {

/**
* @param args
*/
public static void main(String[] args) {
// TODO:
//
// a. declare a final int, and assign a value of 6 as the guessed number
           final int guessed_number = 6;

// b. create a Scanner to get user input
           Scanner input = new Scanner(System.in);
// c. use a do {} while loop to prompt the user to enter an integer between 1 and 10,
// assign the user input to an int, and compare to the guessing number
           int userInput = 0;
do{
System.out.println("Please enter an integer between 1 and 10.");
userInput = input.nextInt();
} while (userInput != guessed_number);

// d. if the number matches the guessed number,
// print out a message that the number entered is correct.
   System.out.println("\nNice! You entered the correct number.\n");

// Here is to print your name
System.out.println("Author: Your Name");
}

respond to the summaries posted please

Methods for Reliable Data Transfers

  • Checksum - Used to detect bit errors in a transmitted packet.
  • Timer - Used to timeout or re-transmit a packet if the packet or ACK was lost. Timeouts can happen when a packet is delayed, but not lost (also known as a premature timeout), or when a packet has been received but an ACK is lost.
  • Sequence number (seq. no.) - Used for sequential numbering of packets of data flowing from sender to receiver. Gaps in the sequence numbers of received packets allow the receiver to detect a lost packet. Packets with duplicate sequence numbers allow the receiver to detect duplicate copies of a packet.
  • Acknowledgement (ack) - Used by the receiver to tell the sender that a packet or set of packets has been received correctly. ACKs may be individual or cumulative, depending on the protocol.
  • Negative acknowledgement (nack) - Used by the receiver to tell the sender that a packet has not been received correctly. Nacks will carry the sequence number of the packet that was not received correctly.
  • Window (or pipelining) - Sender may be restricted to only send packets within sequence numbers of a given range. By allowing multiple packets to be transmitted, but not yet acked, sender utilization can be increased over a "stop-and-wait" mode of operation.

COPIED Question>

" Fitzgerald Law, LLP, a local attorney's firm, has contacted you as they have heard good things about your network design skills. They currently have a wireless network set up for the law firm but would like to allow clients and internal staff to browse the web while they are visiting the firm. They are worried, however, about the security considerations that go with this extension of their network.

Fitzgerald Law has requested that you send them your ideas and recommendations in memo form on how to create one overall network that incorporates the two wireless networks (the protected law firm network and the unprotected public network). They would like to see a diagram of the entire network, costs, and how long it would take to implement. Lastly, they would like to have you give them ideas of how you will make sure this network is secure, outlining what tools you may use to make it so. Answer all of Fitzgerald Law's questions, including a diagram. You can create the diagram. "

use *python

Though CPUs, and computer hardware in-general, are not the main focus of this course, it can be useful to know a thing or two about computer hardware. The CPU (Central Processing Unit) is generally the piece of hardware that carries out the instructions of the python programs that you run in this class.

In this short PA, you will write a program that takes a few input values related to CPU performance. The program should determine whether or not the specified CPU is within one of four categories: high-performance, medium-performance, low-performance, and in need of an upgrade. Name the file cpu.py. Shown below is an example of the program prompting the user for three inputs, and then printing out the corresponding CPU performance category:

Press ENTER or type command to continue
Enter CPU gigahertz:
2.7
Enter CPU core count:
2
Enter CPU hyperthreading (True or False):
False

That is a low-performance CPU
  • The first input, Gigahertz, should be converted to a float
  • The second input, core count, should be an integer
  • The third input, hyperthreading, should be a boolean. You should think of a way to go from a string 'True' or 'False' into a boolean True or False. (In case you were wondering, hyperthreading is a feature of some CPUs allowing for better performancce).

The program should spit out one of 4 strings:

  • That is a high-performance CPU.
  • That is a medium-performance CPU.
  • That is a low-performance CPU.
  • That CPU could use an upgrade.

How you determine which to print out should be based on the below tables:

If the CPU has hyperthreading

performance level min GHz min cores
high-performance 2.7 6
medium-performance 2.4 4
low-performance 1.9 2

If the CPU does not have hyperthreading

performance level min GHz min cores
high-performance 3.2 8
medium-performance 2.8 6
low-performance 2.4 2

There’s also one “special-case” rule: If a CPU has 20 or more cores, regardless of the other stats, it should be considered high-performance.

Examples

Below are several examples of program runs. There will be more tests on Gradescope.

Enter CPU gigahertz:
2.0
Enter CPU core count:
8
Enter CPU hyperthreading (True or False):
True

That is a low-performance CPU.
Enter CPU gigahertz:
4.0
Enter CPU core count:
6
Enter CPU hyperthreading (True or False):
False

That is a medium-performance CPU.

Implement the following functions. Each function deals with null terminated C-strings. You can assume that any char array passed into the functions will contain valid, null-terminated data. Your functions must have the signatures listed below.

1. This function returns the last index where the target char can be found in the string. it returns -1 if the target char does not appear in the string. For example, if s is “Giants” and target is ‘a’ the function returns 2.

int lastIndexOf(char *s, char target)

2. This function alters any string that is passed in. It should reverse the string. If “flower” gets passed in it should be reversed in place to “rewolf”. To be clear, just printing out the string in reverse order is insufficient to receive credit, you must change the actual string to be in reverse order.

void reverse(char *s)

3. This function finds all instances of the char ‘target’ in the string and replaces them with ‘replacementChar’. It also returns the number of replacements that it makes. If the target char does not appear in the string it returns 0 and does not change the string. For example, if s is “go giants”, target is ‘g’, and replacement is ‘G’, the function should change s to “Go Giants” and return 2.

int replace(char *s, char target, char replacementChar)

4. This function returns the index in string s where the substring can first be found. For example if s is “Skyscraper” and substring is “ysc” the function would return 2. It should return -1 if the substring does not appear in the string.

int findSubstring(char *s, char substring[])

5. This function returns true if the argument string is a palindrome. It returns false if it is not. A palindrome is a string that is spelled the same as its reverse. For example “abba” is a palindrome. So is “hannah”, “abc cba”, and “radar”.

bool isPalindrome(char *s)

Note: do not get confused by white space characters. They should not get any special treatment. “abc ba” is not a palindrome. It is not identical to its reverse.

6.This function should reverse the words in a string. Without using a second array. A word can be considered to be any characters, including punctuation, separated by spaces (only spaces, not tabs, \n etc.). So, for example, if s is “The Giants won the Pennant!” the function should change s to “Pennant! the won Giants The”.

void reverseWords(char *s)

Requirements

- You may use strlen(), strcmp(), and strncpy() if you wish, but you may not use any of the other C-string library functions such as strstr(), strncat(), etc.

- You will not receive credit for solutions which use C++ string objects, you must use C-Strings (null-terminated arrays of chars) for this assignment.

In this assignment, you will be implementing a slot machine that you find in casinos. A slot machine has certain number of reels which spin to produce one of a fixed set of symbols (e.g. flowers, bells) randomly when the user pulls a lever. The user needs to insert certain number of currency units as wager into the slot machine before pulling the lever. We refer to these currency units as “wagerUnitValue”. For example in slot machines with quarter (25 cents) as wagerUnitValue , user needs to insert one or more quarters while in dollar slot machines where wagerUnitValue = 100, user needs to insert one or more dollars as wager before pulling the lever. The user will receive a payout based on the matching of symbols on the reels. In a real slot machine there is a payout table which specifies the payout for certain combinations of symbols on the reels. In this assignment, you will instead be implementing simple payout rules based on number of matched symbols.

I have provided a skeletal implementation of a slot machine to help you get started (Check Moodle). Do not change class name, enum type or function signatures. You can however add some variables as needed. Specifically implement the following functions: (a) SlotMachine class constructor which has the following parameters: (i) numReels, (ii) odds array with one entry per symbol indicating probability of getting the symbol in a reel and (iii) wagerUnitValue in cents. (b) getSymbolForAReel() – use Math.random() to generate a random number between 0 and 1 and then use the odds array to generate a symbol randomly. (c) calcPayout() – calculate and return payout value for the given symbols on the reels; use the rules provided in the comments section of the function (d) pullLever() – this function simulates user pulling lever in the slot machine after inserting a wager. First use the function in (b), to generate symbol for each reel and then use the function in (c) to calculate the payout. You can assume that the symbols on the reels appear as independent random events. You need to print the reel symbols in a line followed by the payout in dollar format in another line. (e) getPayoutPercent() – you need to keep track of total wager given by the user as well as total payout provided to the user; this function calculates the total payout as a percent of the total wager value. (f) reset() – clears the total wager and total payout value for fresh calculation of payout percent. Submit only the SlotMachine.java file with your name added in comments section. You can use the main() function to test your program but it is not graded. The test program used for grading will call the class functions (a)-(f) directly.

Create a testbench in Verilog for the following module (logic). Verify the testbench works in your answer. I'll upvote correct answers.

This module does the following. The algorithm takes an input between 0 and 255 (in unsigned binary and counts the number of ones in each number (ex. 01010101 has 4 ones). Then the output would be 00000100 (4 in binary because there are 4 ones.

The test bench would need to verify the inputs and outputs of each number. Test 5 different numbers and ensure the output is expected for the input.

module logic(
  input [7:0] A, //input is between 0-255, so 8 bits.
  output reg [3:0] ones // 0-3 because, at max there can be 8 ones. As, 8 can be represented in 3 bits.
  );

integer i;// declaration of vailable i

always@(A)
begin
ones = 0;  //initialize count variable.
  for(i=0;i<8;i=i+1)   //Iterate all the bits. As input lies between 0 & 255, so, 8 bits.
ones = ones + A[i]; //Adding the bit to the count.
