Random Star
Write a method named randomStar that takes two parameters, a Random object r and an integer num. The method should keep printing lines of * characters, where each line has between 5 and 19 * characters inclusive, until it prints a line with greater than or equal to num characters. num is guaranteed to be between 5 and 19. For example, the method call randomStar(14) will print:
import java.util.*;
public class RandomStar {
public static void main(String[] args) {
Random r = new Random(2063064142); // ignore the 2063064142
randomStar(r, 12);
System.out.println();
randomStar(r, 19);
}
public static void randomStar(Random r, int num) {
}
}

Answer:
Explanation:
The following code is written in Java. The function takes in the random object and creates a random number where it generates a random number and prints out the * characters, if the random number and the input num are the same it prints out both values and ends the function.
import java.util.Random;
class Brainly {
public static void main(String[] args) {
Random r = new Random();
randomStar(r, 12);
System.out.println();
randomStar(r, 19);
}
public static void randomStar(Random r, int num) {
while (true) {
int randomNum = r.nextInt(19) + 5;
if (randomNum != num) {
for (int x = 0; x < randomNum; x++) {
System.out.print("*");
}
System.out.print("\n");
} else {
for (int x = 0; x < randomNum; x++) {
System.out.print("*");
}
System.out.print("\n");
System.out.println("Random Number: " + randomNum);
System.out.println("Input Number: " + num);
break;
}
}
}
}

In this lab, you complete a partially prewritten Python program that uses a list.
The program prompts the user to interactively enter eight batting averages, which the program stores in an array. It should then find the minimum and maximum batting averages stored in the array, as well as the average of the eight batting averages. The data file provided for this lab includes the input statement and some variable declarations. Comments are included in the file to help you write the remainder of the program.
Instructions
Make sure the file BattingAverage.py is selected and open.
Write the Python statements as indicated by the comments.
Execute the program by clicking the "Run Code" button at the bottom of the screen. Enter the following batting averages: .299, .157, .242, .203, .198, .333, .270, .190. The minimum batting average should be .157 and the maximum batting average should be .333. The average should be .2365.

What are you asking for in this problem?
Explanation:
Create a game that rolls two dies (number from 1 to 6 on the side) sequentially for 10 times (use loop). If at least once out of 10 times the sum of two random numbers is equal to 10, you win, else you loose. You will need to get your own method getRandom(int n) that generates a random number, see below (you can modify it as needed), a loop, and IF statement in the loop that checks if a sum of two random numbers is 10 or not.
Please start your program as follows, similar to what we did in class:
import java.util.Random;
public class UseRandom{
//your method getRandom() is here below, n is a range for a random number from 0 to n
public int getRandom(int n)
{
Random r=new Random();
int rand=r.nextInt(n);
return rand;

Counting the character occurrences in a file
For this task you are asked to write a program that will open a file called “story.txt
and count the number of occurrences of each letter from the alphabet in this file.
At the end your program will output the following report:
Number of occurrences for the alphabets:
a was used-times.
b was used - times.
c was used - times .... ...and so, on
Assume the file contains only lower-case letters and for simplicity just a single
paragraph. Your program should keep a counter associated with each letter of the
alphabet (26 counters) [Hint: Use array|
| Your program should also print a histogram of characters count by adding
a new function print Histogram (int counters []). This function receives the
counters from the previous task and instead of printing the number of times each
character was used, prints a histogram of the counters. An example histogram for
three letters is shown below) [Hint: Use the extended asci character 254]:
Answers
Answer:
#include <stdio.h>
#include <ctype.h>

if (counters[i] > largest) {
largest = counters[i];

}
for (row = largest; row > 0; row--) {
for (i = 0; i < 26; i++) {

Suppose we wanted to make change for purchases and wanted to use the least number of coins possible. Here is a greedy algorithm: for the change amount due, we always use the largest-face-value coin first. Assume we have only coins of quarters ($.25), twenties ($.20), and pennies ($.01). Assume the change is $.40: a. what would be the coins and their numbers obtained by the greedy algorithm above
Answers
Answer:
Explanation:
The following code is a Python function that takes in the amount of change. Then it uses division and the modulo operator to calculate the number of coins that make up the changes, using the greatest coin values first.
import math
def amountOfCoins(change):
print("Change: " + str(change))
quarters = math.floor(change / 0.25)
change = change % 0.25
dimes = math.floor(change / 0.20)
change = change % 0.20
pennies = math.floor(change / 0.01)
print("Quarters: " + str(quarters) + "\nDimes: " + str(dimes) + "\nPennies: " + str(pennies))

Using a text editor, create a file that contains a list of at least 15 six-digit account numbers. Read in each account number and display whether it is valid. An account number is valid only if the last digit is equal to the remainder when the sum of the first five digits is divided by 10. For example, the number 223355 is valid because the sum of the first five digits is 15, the remainder when 15 is divided by 10 is 5, and the last digit is 5. Write only valid account numbers to an output file, each on its own line. Save the application as ValidateCheckDigits.java.
