Write a C# console program that continually asks the user "Do you want
to enter a name (Y/N)? ". Use a "while" loop to accomplish this. As long as the user enters
either an upper or lowercase 'Y', then prompt to the screen "Enter First and Last Name: " and
then get keyboard input of the name. After entering the name, display the name to the screen.

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.
When you submit your code, please upload your class code(s) and your test code to prove that your code works correctly.

please explain how does the following C code work.
a)
int function1(int num1, int num2) {
int num = num1 ^ num2;
int result = 0;
while(num > 0) {
result += (num & 1);
num >>= 1;
}
return result;
}
b)
int function2(unsigned int num) {
return num & ~(num - 1);
}
c)
int f1(unsigned int x) {
int count = 0;
while(x) {
count++; x = x&(x-1);
}
return count;
}
d) double ldexp(double x, int exponent) is a C math function
that returns x multiplied
by 2 raised to the power of exponent. How many narrowing and how
many promotions
happen automatically in the following code line? Name them one by
one and explain each
one separately.
float f = 2.2f * ldexp(24.4, 3.0 * 2) - 4.4;
e)
int main() {
int a[] = {1, 2, 3, 4, 5};
int *b = a; int **c = &b;

Below is for C language
typedef struct _node {
Node *next;
char *str;
} Node;
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

-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)

-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.
