Answer:
zip_codes = ["11111", "22222", "33333", "44444", "55555", "66666", "77777", "88888", "99999", "00000"]
charges = [3.2, 4, 1.95, 5.7, 4.3, 2.5, 3.8, 5.1, 6.6, 7.3]
deliver = False
index = -1
zip_code = input("Enter the zip code: ")
for i in range(len(zip_codes)):
if zip_code == zip_codes[i]:
deliver = True
index = i
break
if deliver:
print("The charge of delivery to " + zip_codes[index] + " is $" + str(charges[index]))
else:
print("There is no delivery to " + zip_code)
Explanation:
*The code is in Python.
Initialize the zip_codes array with 10 zip codes
Initialize the charges array with 10 corresponding values
Initialize the deliver as False, this will be used to check if the zip code is in the zip_codes
Initialize the index, this will be used if the zip code is a valid one, we will store its index
Ask the user to enter the zip_code
Create a for loop that iterates the length of the zip_codes array. Inside the loop:
Check if the zip_code is equal to the any of the items in the zip_codes. If it is, set the deliver as True, set the index as i, and break
When the loop is done, check the deliver. If it is True, then print the charge of the delivery. Otherwise, print that there is no delivery to that zip code
Write this program using an IDE. Comment and style the code according to CS 200 Style Guide. Submit the source code files (.java) below. Make sure your source files are encoded in UTF-8. Some strange compiler errors are due to the text encoding not being correct. This lab asks you to create a text game Rock Paper Scissors. The rule of the game: There are two players in this game and they can choose Rock, Paper, or Scissors each time. Rock beats Scissors, Paper beats Rock and Scissors beat Paper. Your program needs to prompt a user to choose an action (Rock, Paper, or Scissors) and save their choice. The program randomly chooses an action (Hint: use .nextInt() to generate random integers in the range of [1,3]. 1 indicates Rock, 2 indicates Paper and 3 indicates Scissors.) Then the program determines who is the winner.
When input is R Please select one of [R/P/S]: You chose: Rock I chose: Scissors Rock beats scissors - you win! If the user enters the lowercase, your program can still recognize. When input is p Output should be Please select one of [R/P/S]: You chose: Paper I chose: Scissors Scissors beat paper - you lose! If the user enters invalid input, the program will give an error message and set the default choice as Rock When input is v Output should be Please select one of [R/P/S]: Invalid choice! Defaulting to Rock. I chose: Scissors Rock beats scissors - you win! If the user has the same result as the computer, your program should output: A Tie!

else //if player loses means if youWin is false
System.out.println("you lose!"); } } //declare player to lose
Explanation:
The program is well explained in the comments attache with each line of program. The program has three methods. One is the main method to start the game and prompts user to enter a choice and converts the user input choice to upper case. One is CompChoice method that generates three random numbers and uses switch statement to set 1 for Rock, 2 for Paper and 3 for Scissors . One method is results that takes computer choice and player choice as parameters to decide the winner. It uses if else statements to check if choice of user wins from choice of computer or vice versa. It uses a boolean variable youWin which is set to true when player choice beats computer choice otherwise is set to false. At the end if youWin is true then the player is declared winner otherwise not. The screenshot of the program output is attached.

Explanation:
please find the complete question in the attached file:
In the above-program code, a double constant variable "Pi" is defined that holds a value, in the next step, a class "Planet" is defined, in the class a default and parameter constructor that is defined that hold values.
In the next step, a get method is used that return value, that is "planet_name, radius, and volume".
In the next step, a method "maxRadius" is defined that accepts two-parameter and calculate the index value, in the main method class type array is defined, and use an array to hold value and defined "idx" to call "maxRadius" method and use print method to call get method.
g Write a function called price_of_rocks. It has no parameters. In a while loop, get a rock type and a weight from the user. Keep a running total of the price for all requested rocks. Repeat until the user wants to quit. Quartz crystals cost $23 per pound. Garnets cost $160 per pound. Meteorite costs $15.50 per gram. Assume the user enters weights in the units as above. Return the total price of all of the material. For this discussion, you should first write pseudocode for how you would solve this problem (reference pseudocode.py in the Week 7 Coding Tutorials section for an example). Then write the code for how you would tackle this function. Please submit a Python file called rocks_discussion.py that defines the function (code) and calls it in main().
Answer:
The pseudocode:
FUNCTION price_of_rocks():
SET total = 0
while True:
INPUT rock_type
INPUT weight
if rock_type is "Quartz crystals":
SET total += weight * 23
elif rock_type is "Garnets":
SET total += weight * 160
elif rock_type is "Meteorite":
SET total += weight * 15.50
INPUT choice
if choice is "n":
break
RETURN total
END FUNCTION
The code:
def price_of_rocks():
total = 0
while True:
rock_type = input("Enter rock type: ")
weight = float(input("Enter weight: "))
if rock_type == "Quartz crystals":
total += weight * 23
elif rock_type == "Garnets":
total += weight * 160
elif rock_type == "Meteorite":
total += weight * 15.50
choice = input("Continue? (y/n) ")
if choice == "n":
break
return total
print(price_of_rocks())
Explanation:
Create a function named price_of_rocks that does not take any parameters
Initialize the total as 0
Create an indefinite while loop. Inside the loop:
Ask the user to enter the rock_type and weight
Check the rock_type. If it is "Quartz crystals", multiply weight by 23 and add it to the total (cumulative sum). If it is "Garnets", multiply weight by 160 and add it to the total (cumulative sum). If it is "Meteorite", multiply weight by 15.50 and add it to the total (cumulative sum).
Then, ask the user to continue or not. If s/he enters "n", stop the loop.
At the end of function return the total
In the main, call the price_of_rocks and print

Problem:
Cookie Calories
A bag of cookies holds 40 cookies. The calorie information on the bag claims that there are 10 "servings" in the bag and that a serving equals 300 calories. Write a program that asks the user to input how many cookies he or she ate and the reports how many total calories were consumed.
*You MUST use constants to represent the number of cookies in the bag, number of servings, and number of calories per serving. Remember to put constants in all caps!
Make sure to declare and initialize all variables before using them!
Then you can do the math using those constants to find the number of calories in each cookie.
Make this program your own by personalizing the introduction and output.
Sample Output:
WELCOME TO THE CALORIE COUNTER!!
Answer:
Here is the Python program:
COOKIES_PER_BAG = 40 #sets constant value for bag of cookies
SERVINGS_PER_BAG = 10 #sets constant value for serving in bag
CALORIES_PER_SERVING = 300 #sets constant value servings per bag
cookies = int(input("How many cookies did you eat? ")) #prompts user to input how many cookies he or she ate
totalCalories = cookies * (CALORIES_PER_SERVING / (COOKIES_PER_BAG / SERVINGS_PER_BAG)); #computes total calories consumed by user
print("Total calories consumed:",totalCalories) #displays the computed value of totalCalories consumed
Explanation:
The algorithm is:
StartDeclare constants COOKIES_PER_BAG, SERVINGS_PER_BAG and CALORIES_PER_SERVINGSet COOKIES_PER_BAG to 40Set SERVINGS_PER_BAG to 10Set CALORIES_PER_SERVING to 300Input cookiesCalculate totalCalories: totalCalories ← cookies * (CALORIES_PER_SERVING / (COOKIES_PER_BAG / SERVINGS_PER_BAG))Display totalCaloriesI will explain the program with an example:
Lets say user enters 5 as cookies he or she ate so
cookies = 5
Now total calories are computed as:
totalCalories = cookies * (CALORIES_PER_SERVING / (COOKIES_PER_BAG / SERVINGS_PER_BAG));
This becomes:
totalCalories = 5 * (300/40/10)
totalCalories = 5 * (300/4)
totalCalories = 5 * 75
totalCalories = 375

Write a program that takes as input a number of kilometers and prints the corresponding number of nautical miles.
Use the following approximations:
A kilometer represents 1/10,000 of the distance between the North Pole and the equator.
There are 90 degrees, containing 60 minutes of arc each, between the North Pole and the equator.
A nautical mile is 1 minute of an arc.
An example of the program input and output is shown below:
Enter the number of kilometers: 100
The number of nautical miles is 54
In python:
kilos = int(input("Enter the number of kilometers: "))
print(f"The number of nautical miles is {round(kilos/1.852,2)}")
I hope this helps!
For an input of 100 kilometers, the program displays "The number of nautical miles is 54.00."
To convert kilometers to nautical miles based on the given approximations.
Here are the simple steps to write the code:
1. Define a function called km_to_nautical_miles that takes the number of kilometers as input.
2. Multiply the number of kilometers by the conversion factor [tex](90 / (10000 \times 60))[/tex] to get the equivalent number of nautical miles.
3. Return the calculated value of nautical miles from the function.
4. Prompt the user to enter the number of kilometers they want to convert.
5. Read the user's input and store it in a variable called kilometers.
6. Call the km_to_nautical_miles function, passing the kilometers variable as an argument, to perform the conversion.
7. Store the calculated value of nautical miles in a variable called nautical_miles.
8. Display the result to the user using the print function, formatting the output string as desired.
Now the codes are:
def km_to_nautical_miles(km):
nautical_miles = (km * 90) / (10000 * 60)
return nautical_miles
kilometers = float(input("Enter the number of kilometers: "))
nautical_miles = km_to_nautical_miles(kilometers)
print(f"The number of nautical miles is {nautical_miles:.2f}.")
The output of this program is:
The result is displayed to the user as "The number of nautical miles is 54.00."

To what does the term "versioning information" refer?
O the version of software that a system is running
the version of your monitor
the number of versions of a virus you have
the version of your PC
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The versioning information refers to the version of the software that a system is running. Versioning of software is the creation and managing of multiple releases of software that all have the same general functionality but improved, modified, upgraded, and customized.
so the correct answer to this question is version information refers to the version of a software that a system is running.
Other options are not correct, because the term version mostly used for software, web application, and web, API services.
The best term use for a version of monitor and PC is model number and also noted that virus detecting software can have version number but the virus itself doesn't have any version number.
So all other options of this question are incorrect except the first option that is:- Versioning information refers to the version of the software that a system is running.
Write a program that reads a list of words. Then, the program outputs those words and their frequencies. The input begins with an integer indicating the number of words that follow. Assume that the list will always contain fewer than 20 words.
Ex: If the input is:
5 hey hi Mark hi mark
the output is:
hey 1
hi 2
Mark 1
hi 2
mark 1
Hint: Use two arrays, one array for the strings and one array for the frequencies.
Answer:
Here is the JAVA program:
import java.util.Scanner; //to accept input from user
public class Main { //class name
public static void main(String[] args) { //start of main method
Scanner input = new Scanner(System.in); //creates Scanner object
int integer = input.nextInt(); //declares and reads the integer indicating the number of words
String stringArray[] = new String[integer]; //creates array to hold strings
for (int i = 0; i < integer; i++) { //iterates through the array
stringArray[i] = input.next(); } //reads strings
int frequency[] = new int[integer]; //creates array for frequencies
int count; //declares variable to count frequency of each word
for (int i = 0; i < frequency.length; i++) { //iterates through the frequency array
count = 0; //initializes count to 0
for (int j = 0; j < frequency.length; j++) { //iterates through array
if (stringArray[i].equals(stringArray[j])) { //if element at ith index of stringArray is equal to element at jth index of stringArray
count++; } } //adds 1 to the count
frequency[i] = count; } //adds count to ith index of frequency array
for (int i = 0; i < stringArray.length; i++) { //iterates through the array
System.out.println(stringArray[i] + " " + frequency[i]); } } } //displays each word in stringArray and its corresponding frequency in frequency array
Explanation:
I will explain the program with an example:
let integer = 3
for (int i = 0; i < integer; i++) this loop is used to read input strings into stringArray.
At first iteration:
i = 0
0<3
stringArray[i] = input.next(); this reads a word and stores it to ith index of stringArray. Lets say user enters the string "hey" so hey is stored in stringArray[0]
i++ becomes i = 1
At second iteration:
i = 1
1<3
stringArray[i] = input.next(); this reads a word and stores it to ith index of stringArray. Lets say user enters the string "hi" so hi is stored in stringArray[1]
i++ becomes i = 2
At third iteration:
i = 2
2<3
stringArray[i] = input.next(); this reads a word and stores it to ith index of stringArray. Lets say user enters the string "hi" so hi is stored in stringArray[2]
i++ becomes i = 3
Now the loop breaks as i<integers evaluates to false.
Next the outer loop for (int i = 0; i < frequency.length; i++)
and inner loop for (int j = 0; j < frequency.length; j++) iterate through the array and if condition if (stringArray[i].equals(stringArray[j])) checks if any of the words at specified indices is equal. This is used in order to check if any word in the list comes more than once. So if any word occurs more than once in the array, then its count is increased each time and the count value is stored in frequency[] array to store the count/frequency of each word in the stringArray. Since hey occurs once so its count is set to 1 and hi occurs twice so its frequency is set to 2. So the output of the entire program is:
hey 1
hi 2
hi 2
