In the file Calculator.java, write a class called Calculator that emulates basic functions of a calculator: add, subtract, multiply, divide, and clear. The class has one private member field called value for the calculator's current value. Implement the following Constructor and instance methods as listed below: public Calculator() - Constructor method to set the member field to 0.0 public void add(double val) - add the parameter to the member field public void subtract(double val) - subtract the parameter from the member field public void multiply(double val) - multiply the member field by the parameter public void divide(double val) - divide the member field by the parameter public void clear( ) - set the member field to 0.0 public double getValue( ) - return the member field
Answer:
Explanation:
The following calculator class written in Java has all the methods and variables requested in the question, each completing their own specific function to the member variable.
class Calculator {
private double member;
public Calculator() {
this.member = 0.0;
}
public void add(double val) {
this.member += val;
}
public void subtract(double val) {
this.member -= val;
}
public void multiply(double val) {
this.member *= val;
}
public void divide(double val) {
this.member /= val;
}
public void clear() {
this.member = 0.0;
}
public double getValue() {
return this.member;
}

Write a program that creates a two-dimensional array initialized with test data. Use any data type you wish. Declare a two-dimensional array of data type char, int, double, or string. Assume the array is declared as follows: const int NUM_ROWS
Question:
Write a program that creates a two-dimensional array initialized with test data. Use any data type you wish. Declare a two-dimensional array of data type char, int, double, or string. Assume the array is declared as follows:
const int NUM_ROWS = 3, NUM_COLUMNS = 5;
test data: [10, 1, 1, 1, 1] [7, 2, 20, 2, 9] [ 3, 3, 3, 3, 5]
Answer:
The program in C++ is as follows:
#include<iostream>
using namespace std;
int main(){
const int NUM_ROWS = 3, NUM_COLUMNS = 5;
int MyArray[NUM_ROWS][NUM_COLUMNS] = {{10, 1, 1, 1, 1},{7, 2, 20, 2, 9},{3, 3, 3, 3, 5}};
return 0;
}
Explanation:
To answer this question, we make use of the following parameters
Array name: MyArray
Array datatype: integer
The explanation is as follows:
This declares the array dimensions
const int NUM_ROWS = 3, NUM_COLUMNS = 5;
This declares and initializes the array with the test data
int MyArray[NUM_ROWS][NUM_COLUMNS] = {{10, 1, 1, 1, 1}, {7, 2, 20, 2, 9}, {3, 3, 3, 3, 5}};
Homework: Insertion Sort
Create a public class named InsertionSorter. It should provide one class method sort. sort accepts an array of Comparables and sorts them in ascending order. You should sort the array in place, meaning that you modify the original array, and return the number of swaps required to sort the array as an int. That's how we'll know that you've correctly implemented insertion sort. If the array is null you should throw an IllegalArgumentException. You can assume that the array does not contain any null values.
To receive credit implement insertion sort as follows. Have the sorted part start at the left and grow to the right. Each step takes the left-most value from the unsorted part of the array and move it leftward, swapping elements until it is in the correct place. Do not swap equal values. This will make your sort unstable and cause you to fail the test suites.
Answer:
Explanation:
I have written the code in Java. It contains the class Insertion Sorter which has the InsertionSort function. This function uses the insertion sort algorithm to sort a comparable array and if it fails to do so for whatever reason it throws an Illegal ArgumentException. If it sorts the array correctly it returns the number of changes that needed to be made in order to correctly sort the array. Due to technical difficulties I have attached the code as a text document below and proof of output in the picture below as well.

Design a program takes as input, X, an unsorted list of numbers, and returns the sorted list of numbers in X. The program must be based on the following strategy: Handle the case when X is empty and has only 1 item. Split X into two lists, using the split function in the previous problem. Sort L and G. Put everything together into a sorted list. Test your program with 10 different unsorted lists.
Answer:
The program in python is as follows:
def split(X):
L = []; G = []
for i in range(len(X)):
if X[i]>=X[0]:
G.append(X[i])
else:
L.append(X[i])
L.sort(); G.sort()
return L,G
X = []
n = int(input("Length of X: "))
for i in range(n):
inp = int(input(": "))
X.append(inp)
if len(X) == 0 or len(X) == 1:
print(X)
else:
X1,X2=split(X)
newList = sorted(X1 + X2)
print(newList)
Explanation:
The following represents the split function in the previous problem
def split(X):
This initializes L and G to empty lists
L = []; G = []
This iterates through X
for i in range(len(X)):
All elements of X greater than 0 equal to the first element are appended to G
if X[i]>=X[0]:
G.append(X[i])
Others are appended to L
else:
L.append(X[i])
This sorts L and G
L.sort(); G.sort()
This returns sorted lists L and G
return L,G
The main function begins here
This initializes X
X = []
This gets the length of list X
n = int(input("Length of X: "))
This gets input for list X
for i in range(n):
inp = int(input(": "))
X.append(inp)
This prints X is X is empty of has 1 element
if len(X) == 0 or len(X) == 1:
print(X)
If otherwise
else:
This calls the split function to split X into 2
X1,X2=split(X)
This merges the two lists returned (sorted)
newList = sorted(X1 + X2)
This prints the new list
print(newList)

Write a program to display MPH (Miles per Hour). Create a function to calculate the MPH. Ask the user for the number of miles driven and the number of minute it took to drive that many miles. Validate that both the number of miles and the number of minutes is a positive, non-zero number. Pass both the number of miles and the number of minutes to the function, and have the function return the MPH.
Answer:
In Python:
def MPH(miles,minutes):
mph = round(60 * miles/minutes,1)
return mph
miles = float(input("Miles: "))
minutes = float(input("Minutes: "))
if miles>0 and minutes>0:
print("MPH: ",MPH(miles,minutes))
else:
print("Positive inputs only")
Explanation:
This defines the function
def MPH(miles,minutes):
This calculates mph rounded to 1 decimal place
mph = round(60 * miles/minutes,1)
This returns the calculated mph
return mph
The main begins here
This gets input for miles
miles = float(input("Miles: "))
This gets input for minutes
minutes = float(input("Minutes: "))
If miles and minutes are positive
if miles>0 and minutes>0:
This calls the MPH function
print("MPH: ",MPH(miles,minutes))
If otherwise, this prompts the user for positive inputs
else:
print("Positive inputs only")

Edna needs a safer car to drive. She likes to travel a lot, so she is looking for a small SUV. She is trying to decide between buying a new or used car. After doing some research, she finds out that most cars lose value each year by a process known as depreciation. You may have heard before that a new car loses a large part of its value in the first 2 or 3 years and continues to lose its value, but more gradually, over time. That is because the car does not lose the same amount of value each year, but it loses approximately the same percentage of its value each year. What kind of model would be most useful for calculating the value of a car over time?
Answer: Buy a new car
Explanation: If its a used car its breaks will be worn out and more likely the breaks will stop working in 6 months and you have to change them. May the forse be with you.

Consider four Internet hosts, each with a TCP session. These four TCP sessions share a common bottleneck link - all packet loss on the end-to-end paths for these four sessions occurs at just this one link. The bottleneck link has a transmission rate of R. The round trip time, RTT, for all fours hosts to their destinations are approximately the same. No other sessions are currently using this link. The four sessions have been running for a long time. What is the approximate throughput of each of these four TCP sessions
The correct response is - The TCP protocol creates a three-way connection between hosts on a network to send packets. It is a connection-oriented protocol. It is a protocol found in the OSI network model's transport layer. Given that all lost packets are sent again, it is trustworthy.
What is a TCP protocol?One of the key protocols in the Internet protocol family is the Transmission Control Protocol. It was first used to supplement the Internet Protocol in the first network installation. TCP/IP is the name given to the full suite as a result.
The usage of TCP allows for the safe exchange of data between the server and the client. No matter how much data is transferred across the network, it ensures its integrity. It is therefore used to transfer data from higher-level protocols that demand the arrival of all sent data.
