Create a Patient class which has private fields for patientid, lastname,

firstname, age, and email. Create public data items for each of these private fields with get and

set methods. The entire lastname must be stored in uppercase. Create a main class which

instantiates a patient object and sets values for each data item within the class. Display the

data in the object to the console window.

---

Modify the Patient class with two overloaded constructors: A new default

constructor which initializes the data items for a patient object using code within the

constructor (use any data). A second constructor with parameters to pass all the data items

into the object at the time of instantiation. Create a test main class which instantiates two

objects. Instantiate the first object using the default constructor and the second object using

the constructor with the parameters.

---

Modify the main class in the patient application to include a display

method that has a parameter to pass a patient object and display its content.

---

Modify the patient class with two overloaded methods to display a bill for a

standard visit based on age. In the first method do not use any parameters to pass in data. If

the patient is over 65, then a standard visit is $75. If the patient is under 65, then the standard

doctors office visit is $125. Build a second method where you pass in a discount rate. If the

patient is over 65, then apply the discount rate to a standard rate of $125. Create a main

method that calls both of these methods and displays the results.

-----

Create two subclasses called outpatient and inpatient which inherit from

the patient base class. The outpatient class has an additional data field called doctorOfficeID

and the inpatient class has an additional data item called hospitalID. Write a main method that

creates inpatient and outpatient objects. Sets data for these objects and display the data.

---

Modify the base class of Problem 5 to be an abstract class with an abstract

display method called displayPatient that does not implement any code. Create specific

implementations for this method in both the outpatient and inpatient subclasses

In this assignment, you are asked to create a class called Account, which models a bank account. The requirement of the account class is as follows, (1) It contains two data members: accountNumber and balance, which maintains the current account name and balance, respectively. (1) It contains three functions: functions credit() and debit(), which adds or subtracts the given amount from the balance, respectively. The debit() function shall print ”amount withdrawn exceeds the current balance!” if the amount is more than balance. A function print(), which shall print ”A/C no: xxx Balance=xxx” (e.g., A/C no: 991234 Balance=$88.88), with balance rounded to two decimal places.

num >>= 1;
}
return result;
}

b)

Below is for C language

typedef struct _node {

Node *next;

You are given a function that takes in two Node* pointers to two different linked lists. Each linked list node has a string represented by a character array that is properly null terminated. You're function is supposed to return true if the concatenation of strings in a linked list match each other, else return false.

EXAMPLES

List 1: "h" -> "el" -> "l" -> "o" -> NULL

List 2: "he" -> "llo" -> NULL

Return: True

List 1: "je" -> "lc -> "l" -> "o" -> NULL

List 2: "h" -> "e" -> "ll" -> "" -> "o" -> NULL

Return: False

List 1: “e” -> “llo” -> “h” -> NULL

List 2: “h” -> “e” -> “l” -> “l” -> “o” -> NULL

Return: False

C++ programming question

1. Write a program that will read input from a text file called "theNumbers.txt" (you will have to provide your own when debugging). The text file that is to be opened is formatted a certain way, namely, there is always one integer, one character (representing an operation), another integer, and then a new line character, with spaces between each item. A sample text file is provided below.

theNumbers.txt

144 + 26

3 * 18

88 / 4

22 – 8

16 / 2

20 * 20

-Your Program should read in all items, compute the answer to each expression (any decimals should be rounded to the nearest tenth), and output the answers to an output file of the user's choosing. The formatting of the output is that there is a set width of 10 characters for each answer, left aligned, with a new line character every 3 answers. A sample “answers.txt” is provided below. (not drawn to scale)

answers.txt

17000      54      22

14               8            400

-You may assume that the name of the text file that will be outputted to is always 20 characters or less.

-You may assume that there are only 4 possible operations ( + - *   /), add, subtract, multiply, and decimal division, and that no other characters will show up as the middle symbol.

- Appropriate error messages should be displayed if the file cannot be opened.

- Extra Credit: The answers in the output file ONLY show a decimal if the answer is not a whole number answer.

Exercise 1

Using the following list, do the following:

1. Sort it in ascending order
2. In a print statement, referencing the list and its index numbers, print the lowest value and the highest value.

[15, 70, 15, 38, 49, 98, 62, 89, 2, 21, 40, 74, 36, 36, 65, 1, 55, 16, 24, 56]

Exercise 2 (1 Point):

Using the following list, do the following:

1. Iterate through each element in the list

2. Print out whether the element is positive or negative or zero on a new line for each element.

[-2, 1, -2, 7, -8, -5, 5, 10, -6, 7]

Exercise 3 (2 Points):

Create a new list using the range function, appending the values from the range function's output into the list.

The range function must:

1. Start at 1
2. Stop at 50
3. Skip every other number

Hint: Use either a for loop or a list comprehension

Exercise 4 (6 Points):

In this exercise, you will be required to do the following:

Take the following phrase: The only thing we have to fear is fear itself

1. Convert it to a list
2. Inspect each word in the list
   1. If the word in the list starts with a vowel (excluding y), then:
      1. add the letters "way" to the end of the word.
      2. EX: the word "and" would become "andway"
   2. If the word in the list does not start with a vowel (including y), then:
      1. take the first letter from the word and move it to the end of the word
      2. add to the end of the word, the letters "ay"
      3. EX: the word "money" would become "oneymay"
3. Append each modified word to a new list
4. convert the list to a string and print that string out
   1. HINT: use join()

So, the end result should be:
