Java Problem:
Array lists and linked lists are both implementations of lists. Give an example of a situation where an array list would be the better choice and one where a linked list would. Explain the reasons in each case. Provide example.

I am currently working on this problem. It says it is wrong, and I was wondering if someone could correct my code to where its ouput is as followed.
Expected Output:
6↵ 5↵ 4↵ 3↵ 2↵ 1
Actual Output:
9↵ 8↵ 7↵ 6↵ 5↵ 4↵ 3↵ 2↵ 1↵ 0↵
9.10: Reverse Array
Write a function that accepts an int array and the array’s size as
arguments. The function should create a copy of the array, except
that the element values should be reversed in the copy. The
function should return a pointer to the new array. Demonstrate the
function by using it in a main program that reads an integer
N (that is not more than 50) from
standard input and then reads
N integers from a file named
data into an array. The program then
passes the array to the your reverse array function, and prints the
values of the new reversed array on standard output, one value per
line. You may assume that the file data
has at least N values.
Prompts And Output Labels. There are no prompts for the integer and no labels for the reversed array that is printed out.
Input Validation. If the integer read in from standard input exceeds 50 or is less than 0 the program terminates silently.
I used this code:
#include<iostream>
#include<fstream>
using namespace std;
int *reverse(const int *, int);
int main()
{
int N;
N=10;
/*
cin >> N;
if(N > 50 || N < 0)
exit(0);
*/
// int *arr1 = new int[N], index;
int *arr1=new int[N];
int index;
for(int i=0;i<N;i++)arr1[i]=i;
/*
fstream datafile;
datafile.open("data.txt", ios::in | ios::out);
for(index = 0; index < N; index++)
{
datafile >> arr1[index];
}
*/
int *temp;
temp = reverse(arr1,N);
for(index = 0; index < N; index++)cout << temp[index]
<< endl;
system("PAUSE");
}
int *reverse(const int *arr1, int N)
{
int index = N-1;
int *arr2;
arr2 = new int[N];
for(int count = 0; count < N; count++)
{
arr2[count] = arr1[index];
index--;
}
return arr2;
}

C# Arrays & methods
I'm having trouble implementing the GetIntArrayFromUser method in the following problem:
Create a method AverageIntArray that takes an array of integers
and calculates and returns the average of all values in the array
as a double Write a program that uses GetIntArrayFromUser method to
get an array of 7 numbers, then calls the AverageIntArray method to
get the average then prints all values in the array that are
greater than the average.
Sample run:
Enter next whole number: 3
Enter next whole number: 8
Enter next whole number: 4
Enter next whole number: 12
Enter next whole number: 13
Enter next whole number: 6
Enter next whole number: 9
Average: 7.85714285714286
8
12
13
9
here is GetIntArrayFromUser:
public void GetIntArrayFromUser()
{
Console.WriteLine("Enter number of list items");
int size = Convert.ToInt32(Console.ReadLine());
int[] arr = new int[size];
for (int i = 0; i < size; i++)
{
Console.WriteLine("Enter next whole number");
arr[i] = Convert.ToInt32(Console.ReadLine());
}
Console.WriteLine("Items in the list: ");
foreach (int item in arr)
{
Console.WriteLine(item);
}
}

Write a boolean function named isMember that takes two
arguments: an array of type
char and a value. It should return true if the value is found in
the array, or false if the
value is not found in the array.

Rather than clutter up the source code with blocks of essentially the same calculations or blocks of code controlled by IF then…else logic, we can move these blocks of code into one location that can be called from anywhere and anytime during the application’s execution, the “function”.
Functions can be passed “arguments”, one or more data values and return zero or one value to the calling routine Functions can call other separate functions or even themselves recursively.
If the divisor, n2, is zero, display a message, “Cannot divide by zero” in the function, default n2 to 1, return the dividend and display it in the main.
Example Output:
1 of 2 - Enter First Number: 12.34
2 of 2 - Enter Second Number: 8.4
1 - Add (12.34 + 8.4)
2 - Subtract (12.34 - 8.4)
3 - Multiplication (12.34 X 8.4)
4 - Divide (12.34 / 8.4)

6 – Change Values

Create an application that determines the total due on purchases including sales tax and shipping charges. Allow the user to input any number of item prices. Use a do-while loop such that in the first iteration, you ask the user to enter the price for an item. Keep a counter variable to track the number of items the user has entered by incrementing its value at every iteration. As the last statement for the do{} construct, ask the user if they wish to enter more item prices. Re-execute the do-while loop if the user enters “yes”.
Shipping charges are determined based on the number of items purchased using the following chart (if necessary, use if/else statements for making this decision).
Fewer than 3 items $3.50
3 to 6 items $5.00
7 to 10 items $7.00
11 to 15 items $9.00
More than 15 items $10.00
In addition to the above, if the total purchase (before adding sales tax) is $100.00 or more, then provide free shipping. If the user is $10.00 or less away from reaching a total purchase of $100.00, then display a message prompting the user that they are “that many” dollars away from free shipping. This should be implemented in a way that allows the user to continue entering items if they are close to free shipping.
Sales tax of 7.75% is charged against the total purchase. Display an itemized summary to the user with the following information. Total purchase charge, number of items purchased, sales tax amount, shipping charge, and the grand total. Use proper format specifiers if necessary.

LastNameFirstNameWeek4.java Purpose: This program will take an order on a local beverage parlor. This beverage parlor offers a limited set of drinks by a glass. Any day of the week (except Mondays when they are closed) they offer three possible alternatives: “Juice”, “Milk”, or “Soda”. Additionally only Fridays, Saturdays and Sundays, the beverage parlor serve also “Beer” and “Wine”. The program should ask the users for her/his beverage choices and produce a summary of the order in the end. To do so, the program will initially get the name of a day in a week (Monday, Tuesday, Wednesday, etc.) from the user. If the day is Monday, the program should print “Sorry. This establishment is closed on Mondays. Your order includes nothing.” And the program will stop. If the day is Tuesday, Wednesday or Thursday, the program will ask the user: “Which beverages would you like to drink?: juice, milk, or soda?" and receive the answer. If the day is Friday, Saturday or Sunday, the program would ask to the user: "Which beverages would you like to drink?: juice, milk, soda, beer, or wine?" and get an answer. After every new beverage order, the program will ask if the user wants to order something else. If the user wants to order something else, the requesting process is repeated within a loop, but the day given at the beginning of the session will remain. Every time the user selects one of the beverages, a corresponding counter for each of these meals should be updated (adding 1 to it). When the user indicates s/he does not want to order more, the program will print the total order with the correct count of each beverage that was ordered and stop. If a beverage was not ordered, its name must not appear in the final list. Notice that responses from the user may be entered in any combination of uppercase or lowercase letters. The best will be to read all responses using the next() method of the Scanner, convert these responses to uppercase letters with the toUpperCase() method of the String class, and use this uppercase version of the response to do comparisons with the choices (also in upper case). Your output should be similar to the samples shown below. Do not change the order of the questions neither the messages that are displayed.
