Write an application that combines several classes and interfaces.
Answer:
Explanation:
The following program is written in Java and it combines several classes and an interface in order to save different pet objects and their needed methods and specifications.
import java.util.Scanner;
interface Animal {
void animalSound(String sound);
void sleep(int time);
}
public class PetInformation {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
String petName, dogName;
String dogBreed = "null";
int petAge, dogAge;
Pet myPet = new Pet();
System.out.println("Enter Pet Name:");
petName = scnr.nextLine();
System.out.println("Enter Pet Age:");
petAge = scnr.nextInt();
Dog myDog = new Dog();
System.out.println("Enter Dog Name:");
dogName = scnr.next();
System.out.println("Enter Dog Age:");
dogAge = scnr.nextInt();
scnr.nextLine();
System.out.println("Enter Dog Breed:");
dogBreed = scnr.nextLine();
System.out.println(" ");
myPet.setName(petName);
myPet.setAge(petAge);
myPet.printInfo();
myDog.setName(dogName);
myDog.setAge(dogAge);
myDog.setBreed(dogBreed);
myDog.printInfo();
System.out.println(" Breed: " + myDog.getBreed());

How should you present yourself online?
a
Don't think before you share or like something
b
Argue with other people online
c
Think before you post
d
Tag people in photos they may not like
hurry no scammers
Answer: C) Think before you post.
Explanation:
There's a very good chance that whatever you post online will remain there indefinitely. So it's best to think about what would happen if you were to post a certain message on a public place. Keep in mind that you should also safeguard against your privacy as well.
You will write code to manipulate strings using pointers but without using the string handling functions in string.h. Do not include string.h in your code. You will not get any points unless you use pointers throughout both parts.
You will read in two strings from a file cp4in_1.txt at a time (there will be 2n strings, and you will read them until EOF) and then do the following. You alternately take characters from the two strings and string them together and create a new string which you will store in a new string variable. You may assume that each string is no more than 20 characters long (not including the null terminator), but can be far less. You must use pointers. You may store each string in an array, but are not allowed to treat the string as a character array in the sense that you may not have statements like c[i] = a[i], but rather *c *a is allowed. You will not get any points unless you use pointers.

You plan to make a delicious meal and want to take the money you need to buy the ingredients. Fortunately you know in advance the price per pound of each ingredient as well as the exact amount you need. The program should read in the number of ingredients (up to a maximum of 10 ingredients), then for each ingredient the price per pound. Finally your program should read the weight necessary for the recipe (for each ingredient in the same order). Your program should calculate the total cost of these purchases, then display it with 6 decimal places.
Example There are 4 ingredients and they all have a different price per pound: 9.90, 5.50, 12.0, and 15.0. You must take 0.25 lbs of the first, 1.5 lbs of the second, 0.3 lbs of the third and 1 lb of the fourth. It will cost exactly $29.325000.
Answer:
In Python:
prices = []
pounds = []
print("Enter 0 to stop input")
for i in range(10):
pr = float(input("P rice: "+str(i+1)+": "))
pd = float(input("Pound: "+str(i+1)+": "))
if pr != 0 and pd != 0:
prices.append(pr)
pounds.append(pd)
else:
break
amount = 0
for i in range(len(pounds)):
amount+= (pounds[i]*prices[i])
print("Amount: $",amount)
Explanation:
These initialize the prices and pounds lists
prices = []
pounds = []
This prompts the user to enter up to 10 items of press 0 to quit
print("Enter 0 to stop input")
This iterates through all inputs
for i in range(10):
This gets the price of each item
pr = float(input("P rice: "+str(i+1)+": "))
This gets the pound of each item
pd = float(input("Pound: "+str(i+1)+": "))
If price and pound are not 0
if pr != 0 and pd != 0:
The inputs are appended to their respective lists
prices.append(pr)
pounds.append(pd)
If otherwise, the loop is exited
else:
break
This initializes total to 0
amount = 0
This iterates through all inputs
for i in range(len(pounds)):
This multiplies each pound and each price and sum them up
amount+= (pounds[i]*prices[i])
The total is then printed
print("Amount: $",amount)

Three reasons why users attach speakers to their computer
You are responsible for a rail convoy of goods consisting of several boxcars. You start the train and after a few minutes you realize that some boxcars are overloaded and weigh too heavily on the rails while others are dangerously light. So you decide to stop the train and spread the weight more evenly so that all the boxcars have exactly the same weight (without changing the total weight). For that you write a program which helps you in the distribution of the weight.
Your program should first read the number of cars to be weighed (integer) followed by the weights of the cars (doubles). Then your program should calculate and display how much weight to add or subtract from each car such that every car has the same weight. The total weight of all of the cars should not change. These additions and subtractions of weights should be displayed with one decimal place. You may assume that there are no more than 50 boxcars.
Example 1
In this example, there are 5 boxcars with different weights summing to 110.0. The ouput shows that we are modifying all the boxcars so that they each carry a weight of 22.0 (which makes a total of 110.0 for the entire train). So we remove 18.0 for the first boxcar, we add 10.0 for the second, we add 2.0 for the third, etc.
Input

12.0
20.0
5. 33.

Output
- 18.0
10.0
2.0
17.0
-11.0
Answer:
The program in C++ is as follows:
#include <iostream>
#include <iomanip>
using namespace std;
int main(){
int cars;
cin>>cars;
double weights[cars];
double total = 0;
for(int i = 0; i<cars;i++){
cin>>weights[i];
total+=weights[i]; }
double avg = total/cars;
for(int i = 0; i<cars;i++){
cout<<fixed<<setprecision(1)<<avg-weights[i]<<endl; }
return 0;
}
Explanation:
This declares the number of cars as integers
int cars;
This gets input for the number of cars
cin>>cars;
This declares the weight of the cars as an array of double datatype
double weights[cars];
This initializes the total weights to 0
double total = 0;
This iterates through the number of cars
for(int i = 0; i<cars;i++){
This gets input for each weight
cin>>weights[i];
This adds up the total weight
total+=weights[i]; }
This calculates the average weights
double avg = total/cars;
This iterates through the number of cars
for(int i = 0; i<cars;i++){
This prints how much weight to be added or subtracted
cout<<fixed<<setprecision(1)<<avg-weights[i]<<endl; }

If a system contains 1,000 disk drives, each of which has a 750,000- hour MTBF, which of the following best describes how often a drive failure will occur in that disk farm:
a. once per thousand years
b. once per century, once per decade
c. once per year, once per month
d. once per week
e. once per day
f. once per hour
g. once per minute
h. once per second
Answer:
once per month
Explanation:
The correct answer is - once per month
Reason -
Probability of 1 failure of 1000 hard disk = 750,000/1000 = 750 hrs
So,
750/24 = 31.25 days
⇒ approximately one in a month.

Create a public class called Exceptioner that provides one static method exceptionable. exceptionable accepts a single int as a parameter. You should assert that the int is between 0 and 3, inclusive.
If the int is 0, you should return an IllegalStateException. If it's 1, you should return a NullPointerException. If it's 2, you should return a ArithmeticException. And if it's 3, you should return a IllegalArgumentException.
// Begin class declaration
public class Exceptioner {
// Define the exceptionable method
public static void exceptionable(int number){
//check if number is 0.
if(number == 0) {
//if it is 0, return an IllegalStateException
throw new IllegalStateException("number is 0");
}
//check if number is 1
else if(number == 1) {
//if it is 1, return a NullPointerException
throw new NullPointerException("number is 1");
}
//check if number is 2
else if(number == 2) {
//if it is 2, return an ArithmeticException
throw new ArithmeticException("number is 2");
}
//check if number is 3
else if(number == 3) {
//if it is 3, return an IllegalArgumentException
throw new IllegalArgumentException("number is 3");
}
}
}

Write a Python class that inputs a polynomial in standard algebraic notation and outputs the first derivative of that polynomial. Both the inputted polynomial and its derivative should be represented as strings.
Answer:Python code: This will work for equations that have "+" symbol .If you want to change the code to work for "-" also then change the code accordingly. import re def readEquation(eq): terms = eq.s
Explanation:
The function below takes one parameter: an integer (begin). Complete the function so that it prints every other number starting at begin down to and including 0, each on a separate line. There are two recommended approaches for this: (1) use a for loop over a range statement with a negative step value, or (2) use a while loop, printing and decrementing the value each time.
1 - def countdown_trigger (begin):
2 i = begin
3 while i < 0:
4 print(i)
5 i -= 1 Restore original file
Answer:
Follows are code to the given question:
def countdown_trigger(begin):#defining a method countdown_trigger that accepts a parameter
i = begin#defining variable that holds parameter value
while i >= 0:#defining while loop that check i value greater than equal to0
print(i)#print i value
i -= 2 # decreasing i value by 2
print(countdown_trigger(2))#calling method
Output:
2
0
None
Explanation:
In this code, a method "countdown_trigger" is declared, that accepts "begin" variable value in its parameters, and inside the method "i" declared, that holds parameters values.
By using a while loop, that checks "i" value which is greater than equal to 0, and prints "value" by decreasing a value by 2.
