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).

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.

Research Designs

Researchers were interested in learning the effects of trans fats on levels of cholesterol in the blood. Two different research designs were constructed.

Part I: Between-Groups Design

In the between-groups design, researchers were interested in whether cholesterol levels would differ depending on diet. Twenty participants were randomly assigned to one of two different groups. Group A was assigned a diet rich in fruits and vegetables and with no trans fats. Group B participants were asked to follow their normal diets, which contained varying levels of trans fats depending on the individual. After one month, blood samples were drawn and the following levels of cholesterol were obtained:

Part II: Within-Subjects Design

In the within-subjects design, researchers were interested in whether participants could lower their cholesterol levels by changing from a diet higher in trans fats to one with no trans fats. Ten research participants were selected. A baseline measure of cholesterol was taken from each. They were then put on a diet rich in fruits and vegetables and devoid of trans fats for one month. At the end of that month, blood cholesterol was again measured and the following results were obtained:

The management of Bar.Co have asked for your assistance in deciding whether to continue manufacturing a component or buy it from an outside supplier. The component in question is the Sicio that is used as a component on many of the finished products produced by Bar.Co. You have been provided with the following information: 

Bar.Co’s normal annual requirement is for 5,000 Sicios per year. 

Bar.Co’s purchasing department has asked external suppliers to quote for the supply of Sicios. The lowest quotation they have received is for a price of £10 per Sicio for a supply of between 4,000 and 6,000 Sicios per year. 

Sicios are currently manufactured by Bar.Co’s precision engineering department, using specialised machinery. If Sicios are purchased from outside this machinery, which is in the last year of its useful life and not in a condition to be sold, will be scraped at a cost of £200. The net book value of this machinery is £1,000. 

The costs of the precision engineering department, including those associated with the manufacturing of Sicios are estimated to be:

   £

Direct materials    67,500

Direct labour 50,000

Indirect labour 26,500

Light and heat 5,500

Power    3,000

Depreciation (specialised machinery) 1,000

Depreciation (other machinery) 9,000

Other fixed departmental overheads 5,000

The cost accountant of Bar.Co has estimated that the cost of manufacturing Sicios by the precision engineering department is £16.50 per Sicio made up as follows:

   £

Direct materials    3.50

Direct labour 5.60

Departmental overheads    4.60

Company overheads 2.80

The departmental overheads and the company overheads are not specific to Sicio and have been allocated to the component based on direct labour cost.


 The impact on the precision engineering department of ceasing to produce Sicios internally, other than the savings in direct costs specifically associated with manufacturing Sicios, is estimated to be:

Savings of £6,500 in indirect labour; savings of £1,000 in light and heat costs. No savings are expected for power costs and depreciation of other machinery;

An increase in other departmental fixed overheads of £4,000 because of increased activity in goods reception and inspection.

Based on this information the cost accountant is in favour of discontinuing the in-house manufacturing of Sicios.

Required:

a) Prepare a report that identifies, showing any necessary calculations, the total cost for the precision engineering department when Sicios are produced in-house and when they are purchased from an outside supplier, highlighting any difference in each cost item. You are also required to provide your advice regarding the proposed change in the sourcing of Sicios.

b) Discuss any non-financial issues you think should be taken into account in making this decision. Word limit: 400 words.

c) When a business seeks to understand what costs are relevant for a decision, it may have to identify sunk costs and opportunity costs. Explain what you understand by relevant costs, sunk costs and opportunity costs, providing examples. Word limit: 400 words.

Variables typically included in a multivariate demand function (other than the price and quantity of the item the demand function represents) are consumer tastes and preferences, the number of buyers, spendable (disposable) income, prices of substitute goods, prices of complementary goods, advertising expenditures, weather, and expectations. Recalling that the price of the item being considered is placed on the vertical axis, and the quantity on the horizontal axis, the other variables are termed demand shifters.

Background

You are the owner of AAA Landscaping, a small company in Orlando, Florida, that specializes in resodding and maintenance of lawns. Much of your business is through word-of-mouth advertising. Once a contract is negotiated, portions of it are subcontracted out to other companies (e.g., sprinkler system repair and pesticide services). Recently, you went to the home of Stu Murphy to bid on resodding his lawn. He obtained several other bids, but yours was the lowest. You arranged for work to begin to remove old grass and replace it with the St. Augustine grass sod that he requested. As part of the contract, Stu also asked that some basic maintenance be done (e.g., hedge and tree trimming, hauling away of old decorative wooden logs from around flower beds, and general sprucing up of the front area of the house). In addition, fertilizer and pesticide were to be applied within two weeks. Stu signed the contract on Wednesday and the work was to be completed by Saturday, when he had planned a party.

Your Role

You were pleased to get the contract, worth over S 1,200. This is actually the third or fourth contract in the same subdivision because of word-of-mouth advertising. Your employees completed the initial sod removal and replacement, weeding, and pruning on Friday, and you received full payment on Monday. You received a call from Stu on Tuesday afternoon stating that several trees were not trimmed to his satisfaction, debris covering decorative

rocks along hedges was not removed as agreed, and bags of clippings had been left behind. Because of other commitments, it was only on Friday that you sent someone out to finish the job. On Saturday, Stu left another message on your answering machine stating that there was still an untrimmed tree, the debris remained, and the clippings were still in the side yard. You did not get around to returning his call. Stu called again Monday, repeating the message he had left before and reminding you that the contract called for pesticide and fertilizer to be

applied to the lawn. You called back and said that someone would be out the next day. Again, other commitments kept you from following through. Stu called on Wednesday and left a fourth message on your answering machine. He said that he was getting irritated at not getting callbacks and action on his needs. Without returning Stu's call, you responded by sending someone out on Thursday to take care of the outstanding work. It has been several days since the work was completed, and you assume that Stu is now satisfied since you have heard nothing else from him.

Critical Thinking Questions

1. Based on information in this chapter, how have you done on providing service to Stu? Explain.

2. What were Stu's needs in this case?

3. Could you have done anything differently?

4. Are you sure that Stu will give a good recommendation to neighbors or friends in the future? Why or why not?
