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.

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
5
40.0
12.0
20.0
5. 33.
0
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; }
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());
}
}
class Pet implements Animal{
protected String petName;
protected int petAge;
public void setName(String userName) {
petName = userName;
}
public String getName() {
return petName;
}
public void setAge(int userAge) {
petAge = userAge;
}
public int getAge() {
return petAge;
}
public void printInfo() {
System.out.println("Pet Information: ");
System.out.println(" Name: " + petName);
System.out.println(" Age: " + petAge);
}

Explanation:
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.

4 reasons why users attach speakers
to their computers
Answer: we connected speakers with computers for listening voices or sound because the computer has not their own speaker. the purpose of speakers is to produce audio output that can be heard by the listener. Speakers are transducers that convert electromagnetic waves into sound waves. The speakers receive audio input from a device such as a computer or an audio receiver.
