C++ Visual Studio 2019

Part A :

Program Description:

Write a program to generate a report based on input received from a text file. Suppose the input text file student_grades.txt contains the student’s Last name , First name, SSN, Test1, Test2, Test3 and Test4. (25%)

i.e.

Alfalfa   Aloysius   123-45-6789 40.0    90.0   100.0    83.0

Generate the output Report File student_final.txt in the following format :

LastName FirstName   SSN Test1   Test2   Test3   Test4 Average FinalGrade

i.e.

Alfalfa   Aloysius   123-45-6789 40.0    90.0   100.0    83.0    78.25 .0   C+

The program must be written to use the enum letterGrade :

enum letterGrade {A_PLUS,A, A_MINUS,B_PLUS,B, B_MINUS, C_PLUS,C, C_MINUS,D_PLUS,D, D_MINUS,F } ;

Use the following function prototype for deriving letter grade :

letterGrade deriveGrade(double average) ;

The average is calculated as follows : (test1 + test2 + test3 + test4)/4.0

The function deriveGrade should derive the letterGrade of the student based on the following grading scale :

Also provide the following function :

         string convertToText(letterGrade grade) ; //This function converts a letterGrade type to a string type.

Requirement :

• The namespace ‘gradeOpt’ definition should contain the following members :(15%)
  1. the enum letterGrade definition,
  2. deriveGrade(..) function prototype and
  3. convertToText(…) function prototype
• Add the namespace ‘gradeOpt ‘ to the grade.h header file and the namespace member function definitions to the file grade.cpp file. (10%)

Input text file student_grades.txt

make a C++ program to calculate total water bill for a customer. The water company charges $250.00 for <=1000 gallons of water. Over 1000 gallons the company charges .99 / gallons

The program displays

Gallons of water used = xx

Exatra payment= xx

Total payment = xx

Write a program that does the following in order:

1. Ask user to enter a name

2. Ask the user to enter five numbers “amount1”, “amount2”, “amount3”, “amount4”, “amount5”

3. Calculate the sum of the numbers “amount1”, “amount2”, “amount3”, “amount4”, “amount5”

4. If the sum is greater than 0, print out the sum

5. If the sum is equal to zero, print out “Your account balance is zero”

6. If the sum is less than 0, print out “Your account is overdrawn” and the “negative amount”

7. Round all print values to 1 decimal place

Round your sum output to 2 decimal places

make a C++ program to calculate discount for a customer.

If customer code equals 1 discount = 5%

Any other code discount = 2%

Display the discount

Question 3. A string p = p₁…p_n is a palindrome if it spells the same string when read backward, that is p_i = p_{n+1 –i} for 1≤ i ≤ n. Design an efficient algorithm for finding all palindromes (of all lengths) in a text. (The pseudo code the algorithm should be provided) (40 points)

The stages of the classical waterfall model for software development consist of requirements, design, implementation, testing, deployment, and maintenance. Why does picturing the development of software to run on mobile applications, business-based systems, or Internet environments help to ensure the success of the development effort? What might happen otherwise? What is the professionalism with respect to software engineering? What do you do, as a software engineer involved in a software systems development project, to ensure that the product is better because of your participation in the development effort?

Answer any 3 questions

Please write in Java and have two methods: the main method and the reverse word

Write a method that reads a line and reverses the words in the line (not the characters) using a stack. For example, given the following input:

The quick brown fox jumps over the lazy dog

you should get the following output:

dog lazy the over jumps fox brown quick The

Then create a main method to prompt the user to enter a line of words to be reversed using the previous reverse method.

Consider the following IPv4 forwarding table, using CIDR. As in exercise 1, IP address bytes are in hexadecimal, and “:” is used as the separator as a reminder.

(a). To what next_hop would each of the following be routed? 63:b1:82:15, 9e:00:15:01, de:ad:be:ef

(b). Explain why every IP address is routed somewhere, even though there is no default entry. Hint: convert the first bytes to binary

Your assignment is to write a C++ program to read a text file containing the information of the employees of a company, load them into memory and perform some basic human resources operations. This assignment will help you practice: multiple file programming, classes, public and private methods, dynamic memory allocation, constructors and destructors, singly linked list and files.

Implementation

This lab assignment gives you the opportunity to practice creating classes and using dynamic memory in one of the required classes. There are two classes to implement Employee and Company. #the Company will hold a linked list of Employees. This list of employees is modeled using linked nodes of Employee* (pointers to Employees). These employees are created dynamically when they are added to the list.

You will create the following files:

• menu.cpp: contains your main function
• employee.h: contains the Employee class declaration
• employee.cpp: contains the Employee class method definitions
• company.h: contains the Company class declaration
• company.cpp: contains the Company class method definitions

Class Descriptions

Employee

Notice there are no changes from previous Employee implementation

Company

Employee::ToString(), returns a formatted string following the following format:

ID: 1 Name: Peter Salary: 250 Manager ID: 0

Widths:

• ID: 4
• Name: 10
• Salary: 10
• Manager ID: 4

Program Menu

Your program should output the following menu:

1. Load from File
2. Save to File
3. List all Employees
4. Search by Name
5. Search by ID
6. Find Employee Boss Information
7. Add new Employee
8. Check if Database is Full
9. Exit

1. Write a function in Python to compute the sample mean of a list of numbers. The return value should be the sample mean and the input value should be the list of numbers. Do not use a built-in function for the mean. Show an example of your function in use.

Write a function that removes all even numbers from an array. The function should take the array, length of the array, and a pointer for number of odd numbers found as arguments and return a pointer to the new array. If there are no odd numbers found in the array, your code should print "No odds found." and return NULL.

Use the function header:

int *removeEvens(int *a, int length, int *oddsFound);

Example:

Input array a[ ] = {3, 4, 5, 6, 7}

*oddsFound = 3

return array = {3, 5, 7}

The size of the return array needs to be the number of odd numbers found.

Note: You can determine if a number is even by checking if a[x] % 2 == 0.

Consider the relational schemas given below and the respective sets of functional dependencies valid in the schemas. For each one of the relational schemas identify its highest normal form. Remember that the identification of a normal form requires analysis of the valid functional dependencies and the minimal keys. Provide justification of each answer. A solution with no comprehensive justification scores no marks.

(iv) When a staff is required to undertake an inspection of properties, the staff is allocated a company car for the day. A staff may inspect several properties on a given date, and a property is only inspected once on a given date. These information of the inspection are stored in the following relational table:
PropertyInspection(PropertyNum, IDate, ITime, Comments, StaffNum, CarRegNum)

(vi) Each student is assigned with a counselor who will act as an advisor to the students. The student is given the counselor email address so that the student can contact the counselor for advice. The information on the student and counselor are stored in the following relational table.
STUDENTCOUNSELOR (StdNum, StdName, CounselorName, CounselorEmail)
