Write a C++ program that takes input from the keyboard of the 3 dimensions of a room (W,L,H in feet) and calculates the area (square footage) needed to paint the walls only. Use function overloading in your program to pass variables of type int and double. You should have two functions: one that accepts int datatypes and one that accepts double datatypes. Also assume a default value of 8 if the height parameter is omitted when calling the functions.

Write a Java program where you will set the datatype and variables to find the value of following expression.

The Values of the variables to be used are given below

a) 101 + 0) / 3

b) 3.0e-6 * 10000000.1

c) true && true

d) false && true

e) (false && false) || (true && true)

f) (false || false) && (true && true)

# Write one while-loop that starts at 500 and prints every 6th number down to 300
# (i.e., prints 500, 494, 488, . . . etc., but does not print any number lower than 300).

# Write one while-loop that starts at 80 and prints every 12h number thereafter,
# but does not print any number greater than 210

# Write one while-loop that prints all the numbers from 30 through 70,
# except for the numbers 41 and 57.

# Write one while-loop that prints the sum of all the even numbers
# (50, 52, 54, . . . etc.,) from 50 through 2000.

# Write one while-loop that prints the count of all the numbers
# from 20 through 2500 that are divisible by 9
# (in other words prints out how many numbers are divisible by 9).

In C: Find a string within a string Given two strings S1 & S2, search for an occurrence of the second string within a first string. Note: Do not use system library for the implementation. Input: Code Zinger University Zinger where, First line represents string S1. Second line represents string S2. Output: 5 Here 'Zinger' word starts at 5th index within 'Code Zinger University’. Assume that, The length of strings S1 & S2 are within the range [1 to 10000]. Character comparisons will be case-sensitive.

Develop a test strategy for testing the entire application chosen in unit 3 for analysis and design. Keep in mind that testing that involves users should minimize their time commitment while obtaining essential information from their involvement. Specifically define roles, responsibilities, timing, and test strategy for each level of testing.

• Consider a simple application-level protocol built on top of UDP that allows a client to retrieve a file from a remote server residing at a well-known address. The client first sends a request with a file name, and the server responds with a sequence of data packets containing different parts of the requested file. To ensure reliability and sequenced delivery, client and server use a stop-and-wait protocol. Ignoring the obvious performance issue, do you see a problem with this protocol? Think carefully about the possibility of processes crashing.

Java programming extra credit.

The following program will be used to test your knowledge on Implementing with tester classes. Included is the Details class. Your assignment is to create a class named DetailsTester using info from the two classes(Procedure class is only included to know the details of the procedure, which includes desc, date, and cost) Patient class is included as well.That will properly implement the class.

package doctorOffice;

import java.util.ArrayList;
import java.time.LocalDate;

public class Details
{
//Instance variables
private Patient patient;
private double height;
private double weight;
private ArrayList procedures = new ArrayList();
private LocalDate lastVisit;

Details(Patient patient,
double height,
double weight)
{
this.patient = patient;
this.height = height;
this.weight = weight;
}

//Getters--------------------------------------
public Patient getPatient()
{
return patient;
}

public double getHeight()
{
return height;
}

public double getWeight()
{
return weight;
}

public ArrayList getProcedures()
{
return procedures;
}

public LocalDate getLastVisit()
{
return lastVisit;
}

//Setters--------------------------------------
public void setHeight(double height)
{
this.height = height;
}

public void setWeight(double weight)
{
this.weight = weight;
}

public void setLastVisit(LocalDate lastVisit)

this.lastVisit = lastVisit;
}

//Methods--------------------------------------
public boolean addProcedure(Procedure toAdd)
{
