Question

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

Question 1:

Application name :ConsoleApp_NameDisplay

Type of application :Console application

Language used :C#

Program.cs :

//namespace
using System;
//application namespace
namespace ConsoleApp_NameDisplay
{
class Program //C# class
{
//main() method
static void Main(string[] args)
{
Console.WriteLine("Do you want to enter a name(Y / N) ? ");
//reading user response
string userResponse = Console.ReadLine();
//using while loop
while(true)
{
//This line will ask user First name and last name
Console.Write("Enter First and Last Name:");
//reading first and last name
string firstLastName = Console.ReadLine();
//display first name and last name
Console.WriteLine(firstLastName);
//asking user whether want to continue
Console.WriteLine("Do you want to enter a name(Y / N) ? ");
//reading user response
userResponse = Console.ReadLine();
//checking firstLastName
if (userResponse.ToUpper()== "Y")
{
//when user response is Y then continue while loop
continue;
}
else
{
break;//break while loop
}
}
}
}
