Complete this programming problem in this assignment by using Microsoft Visual Studio Suite. Compile your solutions for each problem solved in a Word or Google document which includes (a) the pseudocode, (b) the C# codes and (c) the execution result (screen capture just the answer part using Snipping Tool, avoiding non-related or blank spaces). Notice for readability, that the (a) & (b) are in text mode and the (c) is in image mode. Use proper titles and wording in the results, such as Console.WriteLine("The total change to be made is {0:C}.", change); so that the results could be easily understood by a third party reader.

Question: Write a C# program to compute the profit made for selling goldfish flakes online. The wholesale cost for a case of 24-boxes is $118. The price for sale with shipping charge is $9.59 per box. Shipping cost is $1.35 per box. The onlinelisting charge is 12% of the customer payment. The payment processing cost is 4% of the payment. Compute and display the following figures for selling 25 cases of the products: the total wholesale cost for 25 cases; the total revenue for 25 cases of 24 boxes per case, the total listing cost, the total payment processing cost, and the total profit made.

The first assignment involves writing a Python program to compute the weekly pay for a salesman. Your program should prompt the user for the number of hours worked for that week and the weekly sales. Your program should compute the total pay as the sum of the pay based on the number of hours worked times the hourly rate plus the commission. You should choose a value for the hourly pay. The commission should be computed as a percentage of the weekly sales. You should choose a value for the percentage. Your program should output the pay based on the hours worked, the commission and the total pay for the week.

Your program should include the pseudocode, used to come up with the program statements, in the comments. Document the values you chose for the hourly rate and commission percentage in your comments as well.

You are to submit your Python program as a text file (.txt) file. In addition, you are also to submit a test report in a Word document or a .pdf file. 15% of your grade will be based on whether the comments in your program include the pseudocode and define the values of your constants, 70% on whether your program executes correctly on all test cases and 15% on the completeness of your test report.

Identify a situation in your current job or a previous one in which a sales message is or was needed. Using suggestions from this chapter, write an appropriate sales message that promotes a product or service. Use actual names, information, and examples. If you have no work experience, imagine a business you would like to start, such as data processing, pet grooming, car detailing, cleaning, tutoring, specialty knitting, balloon decorating, delivery service, child or elder care, gardening, or lawn care.

Your Task. Write a sales letter or an e-mail marketing message selling your product or service to be distributed to your prospective customers. Be sure to tell them how to respond. You don’t need to know HTML or have a Constant Contact account to craft a concise and eye-catching online sales message. Try designing it in Microsoft Word and saving it as a Web page (go to the File tab and select Save as; then in the Save as type line, select Web page). Consider adding graphics or photos—either your own or samples borrowed from the Internet.

1. Read an unsorted keywords file once to determine how many words are in the file.
2. Allocate memory dynamically to store the unsorted keywords in an array of strings or an array of c-strings. (Hint: be sure to clear your input file stream before re-reading the file)
3. Reread the keywords file a second time and store the words in the dynamically allocated array of strings or c-strings
4. Sort the array of key words. (Hint: be sure to check your sorted array of key words - there should be 84)
5. Search a C++ program input file for occurrences of the keywords:
   • Read one line at a time from the C++ program file into a cstring. (Hint: use the istream::getline function - see example below)
   • Parse each line into separate words. Ignore any words that are inside a C++-style comment. (Hint: use strtok)
   • Search the keyword array to determine if each word is a keyword (Hint: use a binary search or a sequential search)
   • For keywords, print the line number, the keyword, and the position of the keyword in the line. (Hint: use the difference of two pointers)
   • Keep a count of the number of keywords found

Program Requirements

• This zipped file(http://voyager.deanza.edu/~bentley/cis22b/ass4files.zip) contains the keywords file and the C++ program file for searching.
• Use a char array to hold each line from the C++ program file. “Parse” each line into individual words for searching. Note, you may not use the stringstream classes for this assignment.
• Make sure you check the input file for successful opens.
• Your output should match the format show below with the correct line number and position of each word in the line. The line character positions start at zero. Note, there are more than 50 lines of output.

Program Output

Your output should look like this:

Program Hints

• Follow the program steps. Write only one part of the program at a time. Test each part before you proceed to the next step. Do not continue if one part has a problem. Ask for help with a step, if you can't get it to work. Remember to allow plenty of time for this assignment.
• Use a small keyword file and a small test C++ program file initially as you are developing your code.
• Use strstr() to find the // of a C++-style comment.
• Use strtok() for the parsing of each line. You should "parse out" much of the program "punctuation".
• You might want to make a copy of each line (maybe as a string) to determine the position of the keyword in the line. This is because strtok() destroys the original line.
• Xcode users: There is a \r at the end of each line in the test file. You can suppress it by adding "\r" as a delimiter for strtok().
• Your program should produce more than 50 lines of output and you should find more than 70 keywords (many are repeats).

The keyword file looks like this:

The C++ program file looks like this:

AMP has suffered a first strike on its remuneration report after coming under fire from shareholders and proxy advisers over the “disproportionately large” incentives paid to its executives. At the company’s virtual annual general meeting on Friday, 67 per cent of proxies voted against the remuneration report. It comes after influential proxy advisers Ownership Matters and ISS recommended shareholders vote against the generous pay packages. Both proxy advisers last month argued that executive pay was overly generous and performance hurdles not rigorous enough. If the company receives a second strike next year, it will trigger a board spill under the ‘two-strikes’ rule. Commenting on the executive remuneration plan, Mr Murray [Chair of the Board] said the generous package was required to attract and retain an executive team that could execute the company’s transformation strategy. “The 2019 remuneration structure was designed to reflect the scale, complexity and challenges involved in transforming the business … executing an ambitious strategy, separating the life insurance business, completing client remediation and addressing the company’s challenging regulatory and legal matters. “In our CEO and executives, we have a capable and driven team to deliver our plan. Their awards are substantial, but the hurdles are challenging. For the awards to be realised over the long term, these demanding hurdles must first be achieved, including a significant improvement in business performance and share price,” Mr Murray said. Taking aim at the two-strike rule, which sees a board spill if more than 25 per cent of shareholders vote against a company’s remuneration report two years in a row, Mr Murray warned it reduced the incentive for companies to “properly invest in specialist care, ultimately leaving the more difficult workouts to the unlisted markets”. AMP chief executive Francesco De Ferrari’s pay package came in at $13.43m last year, buoyed by share rights, options and restricted shares, even as the under-pressure wealth group posted losses of $2.5bn. Mr De Ferrari’s remuneration for the 12 months ended December 31 included a $2.18m base salary, $1.32m cash bonus, other short-term benefits of $1.71m and almost $8.2m in rights, options, and restricted shares. Extract from Grieve, C. Shareholders hit AMP with first strike against executive pay packets. The Australian. 8 May 2020. Required: From the information provided: a) Do you think that remuneration incentives are working in the way intended under agency theory for AMP Ltd? Why or why not?

Researchers claim that women speak significantly more words per day than men. One estimate is that a woman uses about 20,000 words per day while a man uses about 7,000 . To investigate such claims, one study used a special device to record the conversations of male and female university students over a four‑day period. From these recordings, the daily word count of the 2020 men in the study was determined. The table contains their daily word counts.

(a) Use the software of your choice to make a histogram of the data. What value should we remove from the data to make it reasonable to use the t procedures (assume these men are an SRS of all male students at this university)?

value to remove:

(b) With this value removed, carry out a test of significance to determine if the mean number of words per day of men at this university differs from 7000. (If you're using CrunchIt for your calculations, adjust the default precision under Preferences as necessary. See the instructional video on how to adjust precision settings.)

Choose the correct hypotheses to test.

H0:μ=7000 versus H0:μ>7000

H0:μ≠7000H0 versus H0:μ=7000H0

H0:μ<7000H0 versus H0:μ≠7000H0

H0:μ=7000H0 versus H0:μ≠7000H0

With the value removed, find ¯x . (Enter your answer rounded to two decimal places.)

x¯=

With the value removed, find s . (Enter your answer rounded to three decimal places.)

s=

With the value removed, find t . (Enter your answer rounded to three decimal places.)

t=

Using the software of your choice, find the P‑value. (Enter your answer rounded to four decimal places.)

P=

What conclusion can we make from this data? Choose the correct answer.

A.There is no evidence that the mean number of words per day of men at this university differs from 7000 The sample mean indicates they speak less than 7000 words per day.

B.There is overwhelming evidence that the mean number of words per day of men at this university differs from 7000The sample mean indicates they speak more than 7000 words per day.

C.There is overwhelming evidence that the mean number of words per day of men at this university differs from 7000The sample mean indicates they speak less than 7000 words per day.

D.There is no evidence that the mean number of words per day of men at this university differs from 7000The sample mean indicates they speak more than 7000 words per day.
