Spring 2019 CMSC 140 Programming Project 4: Days Out

Project Specifications

Input for this project:

• the user must enter the number of employees in the company.
• the user must enter as integers for each employee:
  • the employee number (ID)
  • the number of days that employee missed during the past year.

Input Validation:

• Do not accept a number less than 1 for the number of employees.
• Do not accept a negative number for the days any employee missed.
• Be sure to print appropriate error messages for these items if the input is invalid.

Output: The program should display the following data:

• Each employee number (ID) and the number of days missed should be written to the report file named "employeeAbsences.txt".
• The average number of days a company's employees are absenting during the year should be written to the report file named "employeeAbsences.txt".

• Create a global variable of type ofstream for the output file. Use this variable to open the fileemployeeAbsences.txt in your program to write data to it. A global variable is defined above the main function and its scope is throughout the program.
• Create the following three functions that will be called by the main function:

1. A function called NumOfEmployees. This function asks the user for the number of employees in the company. This value should be returned as an int. The function accepts no arguments (No parameter/input).
2. A second function called TotDaysAbsent that accepts an arguments of type int for the number of employees in the company and returns the total of missed days as an int. This function should do the following:

• 1. Asks the user to enter the following information for each employee:
• The employee number (ID) (Assume the employee number is 4 digits or fewer, but don't validate it).
• The number of days that employee missed during the past year.
  2. Writes each employee number (ID) and the number of days missed to the output file (employeeAbsences.txt). ( Refer to Sample File Output )

3. A third function called AverageAbsent that calculates the average number of days absent.
   1. The function takes two arguments:

• the number of employees in the company
• the total number of days absent for all employees during the year.
  2. This function should return, as a double, the average number of days absent.
  3. This function does not perform screen or file output and does not ask the user for input.

The local bakery bakes more than a thousand 1-pound loaves of bread daily, and the weights of these loaves varies. The mean weight is 1.7 lb. and 3 oz., or 856 grams. Assume the standard deviation of the weights is 25 grams and a sample of 32 loaves is to be randomly selected.

(A) This sample of 32 has a mean value of x, which belongs to a sampling distribution. Find the shape of this sampling distribution.

a) skewed right

b) approximately normal   

c) skewed left

d) chi-square

(b) Find the mean of this sampling distribution. (Give your answer correct to nearest whole number.)
_____ grams

(c) Find the standard error of this sampling distribution. (Give your answer correct to two decimal places.) ______


(d) What is the probability that this sample mean will be between 846 and 866? (Give your answer correct to four decimal places.) _______


(e) What is the probability that the sample mean will have a value less than 847? (Give your answer correct to four decimal places.) _______


(f) What is the probability that the sample mean will be within 4 grams of the mean? (Give your answer correct to four decimal places.) _______

why do we need to test hypotheses in health-related or epidemiological research?

When organizations decide to finance assets, the key is to match meaning current assets with current financing and long term assets with long term financing.

What would be an example of this occurring in business today and what would be the disadvantage from not matching?

If you were tasked with drafting the forms and creating policies at the hospital as a director in administration, how would you deal with this today?

What kinds of policies would you create for the hospital?

What kinds of forms would the patients receive and when would they receive them?

What experts/professionals would you consult to help you create the policies and procedures?

Q3. [15 marks] A solid steel shaft (E = 210 GPa, ? = 0.33) of radius 20 mm has been forced into an aluminium gear (E = 70 GPa, ? = 0.33) of outer radius 40 mm and thickness of 10 mm. There is a radial interference of ? = 0.02 mm. a) Determine the contact (interface) pressure, pc ; [6 marks] b) Sketch the radial stress distribution in the shaft and the gear; [5 marks] c) If the coefficient of friction between the shaft and gear is μ = 0.1, what axial force would be required to move the gear along the shaft? [2 marks] d) What is the maximum torque, which can be transmitted through the shaft? [2 marks] If you cannot solve a) and b) for c) and d) assume pc = 100 MPa.

Imagine that you are the representative of a Chinese food company, and you're hoping to procure a new ingredient for several of your products from a German company. A representative from the German company is flying in to meet with you.

How will you prepare for the meeting to overcome the potential cultural barriers in negotiation?

Explain how Artificial Intelligence could be adopted in the lecture hall for IT101 to enable students have total concentration on the lecture and not to be distracted by anything else (such as putting down notes while the lecture is ongoing, etc.). Discuss, in detail, the components of such system(s) and how each component of such system(s) functions

In Java, how can I convert a string user input for example a student starts a uni degree in "Winter/2022", to a date type, and then once I have done that, add 3 years to that value, and changing the season, so for example Student Started: Winter/2022 and Student Finished: Summer/2025. Is there any possible way to do this?

Thank you.
