Update the following C code and write the function :

void sln_stutter(sln_list* li);

that modifies the list li so that it each element is duplicated. For example the list with elements [1,2,3] would after this function call become the list [1,1,2,2,3,3].

#include <stdlib.h>

#include <stdio.h>

  struct sln_node* next;

typedef struct sln_node sln_node;

typedef struct sln_list sln_list;

static sln_node* freelist = NULL;

/* Internal bookkeeping functions for the free list of nodes. */

sln_node* sln_allocate_node() {

  sln_node* n;

  if(freelist == NULL) {

    freelist = malloc(sizeof(sln_node));

  }

  n = freelist;

  freelist = n->next;

  n->next = NULL;

  return n;

}

    n = freelist;

    freelist = freelist->next;

    free(n);

  }

}

/* Create a new singly-linked list. */

sln_list* sln_create() {

  sln_list* list = malloc(sizeof(sln_list));

  list->head = NULL;

  return list;

}

/* Release the list and all its nodes. */

I have a list of things for review in C programming, could you please give me an example and a brief explanation for each question... Thank you very much

• 9. Apply pointer arithmetic to C code
• 10. Explain how multiple files can be organized and run in C, as well as what (recommended) content can be placed in header files
• 11. Explain how a link list can be created (i.e. what the nodes are and what components or syntax can be used to create the nodes)

Suppose we want to make a 10 item queue starting from location x4000. In class, we discussed using a HEAD and a TAIL pointer to keep track of the beginning and end of the queue. In fact, we suggested that the HEAD pointer could point to the first element that we would remove from the queue and the TAIL pointer could point the last element that we have added the queue. It turns out that our suggestion does not work.

Part a) What is wrong with our suggestion? (Hint: how do we check if the queue is full? How do we check if it is empty?)

Part b) What simple change could be made to our queue to resolve this problem?

Part c) Using your correction, write a few instructions that check if the queue is full. Use R3 for the HEAD pointer and R4 for the TAIL pointer.

Part d) Using your correction, write a few instructions that check if the queue is empty. Again, using R3 for the HEAD pointer and R4 for the TAIL pointer.

The two-dimensional arrays list1 and list2 are identical if they have the same contents. Write a method that returns true if they are identical and false if they are not. Use the following header: public static boolean equals(int [][] list1, int [][] list2)

Write a test program that prompts the user to enter two 3 x 3 arrays of integers and displays whether the two are identical.

Enter list1:

Enter list2:

The two arrays are identical or The two arrays are not identical

Here is a picture of a Binary Search Tree.



First, construct the Binary Search Tree using the following BinaryNode as we discussed in class.

public class BinaryNode {
        private int value;
        private BinaryNode leftChild;
        private BinaryNode rightChild;

        public BinaryNode(int value) {
                this.value = value;
                leftChild = null;
                rightChild = null;
        }

        public BinaryNode(int value, BinaryNode leftChild, BinaryNode rightChild)
        {
                this.value = value;
                this.leftChild = leftChild;
                this.rightChild = rightChild;
        }

        public int getValue() {
                return value;
        }

        public void setValue(int value) {
                this.value = value;
        }

        public BinaryNode getLeftChild() {
                return leftChild;
        }

        public void setLeftChild(BinaryNode leftChild) {
                this.leftChild = leftChild;
        }

        public BinaryNode getRightChild() {
                return rightChild;
        }

        public void setRightChild(BinaryNode rightChild) {
                this.rightChild = rightChild;
        }

        @Override
        public String toString() {
                return "BinaryNode: " +
                                "value=" + value;
        }
}

Second, print the nodes in level order, that is, the root node first, then the children of the root node, then the grand-children, etc. It is recommended that you accomplish this by using a queue to store the nodes, printing the first nodes that have been added to the queue.

Your program should print the following when it runs.

42 27 50 21 38 60 33 41 72

Submit the file LevelOrder.java when done.

4. For this question, write code fragments or methods as directed. (a) Create the Point class that depends on a generic data type parameter T. It has two instance variables called xCoordinate and yCoordinate that both have type T. Write a two parameter constructor to initialize the instance variables. Answer: (b) Write a main method that has instructions to perform the following tasks (in order): Declare an ArrayList of Strings called carModels. Add three models. Print the size of the list. Remove the model from index 1. Insert a model at index 0. Replace the model at index 2. Answer: (c) Write a main method with a try-catch block. Inside the block it creates an array of Strings — the array is called list and has size 10. Print the value stored in list[10]. The catch block should catch ArithmeticException and RuntimeException. Your code shouldn’t be longer than 9 lines excluding curly braces. Answer: (d) Write the private method inputCircles that is called by the following main method. As- sume that class Circle exists and has constructors and a toString method. Your method should open a Scanner and obtain a radius for each of the 20 circles that you make from the user. (You should assume that the class Scanner has already been imported.) public static void main(String args[]) { Circle[] data = new Circle[20]; inputCircles(data); for (Circle c:data) System.out.println(c); } Answer:

Is there a way to tell the user in the alert how old they are based on their birthday?

Write a for loop to print all NUM_VALS elements of array hourlyTemp. Separate elements with a comma and space. Ex: If hourlyTemp = {90, 92, 94, 95}, print:

90, 92, 94, 95

Your code's output should end with the last element, without a subsequent comma, space, or newline.

Calculate average test score:

Write a C++ program that calls a function to pass array of test scores of students and calculates the average test scores for each student. Let the user enters 2 students’ test scores for three classes (use two dimensional array). Write another function to pass array of test scores and average to display the test scores for each student and display the average of the test scores for each student as well. So you need to write two functions (one for function to pass array of test scores and average to display the test scores for each student and another for display the average of the test scores for each student as well. ) . You cannot use global variable.

Add version control and write proper comments with a few blank lines & indentations in order to improve your programming style.

Test scores should be between 0-100 (data Validation).

LetsVacuum, a family-owned manufacturer of high-end vacuum cleaners, has grown exponentially over the last few years. However, the company is having difficulty preparing for future growth. The only information system used at LetsVacuum is an old accounting system. The company has one manufacturing plant located in Selangor; and three warehouses, in Johore, Kedah, and Trengganu. The LetsVacuum sales force comprises only Malaysian nationals, and the company purchases about 25 percent of its vacuum parts and materials from a single overseas supplier. You have been hired to recommend the information systems LetsVacuum should implement in preparing for future growth.

1.   In your own terms,
a.   Identify and briefly describe each of the key business functions of LetsVacuum.

Using C++ and using a boolean variable with local scope to control the looping structure:

How do I create a program that will simulate a game of craps with the below qualification:

Containing two functions -an int rollDice() function that will simulate the rolling of two dice and the main function. When called the roll Dice() function will generate two random numbers between 1 and 6 inclusive, add them, and return the sum as the integer variable “point”. The function will also output the value of the “roll” of each digital die and the value of “point” to cout. Selection and looping structures in the int main() function will determine the impact of each roll (win, lose, or roll again) on the game, print the results, and continue the game if necessary.

Create a new public static method called ‘isLatinSquare’ that passes in a two-dimensional array.  This new method will return ‘true’ if the passed array is a Latin Square. ** SHOULD only be 1 or 2 lines of code

Suppose the membership at a fitness club is $500 for individual, $800 for couple and $1200 for 4 people. Every month, the manager at the club says that guests will get discounts for one service per month. He provides you with the list of services that will get a discount:

Your program will be reading in a file which contains a list of services at a fitness club. The discount is determined by the type of service. For example, the file is as follows:

Cafe: Smoothies

SPA: Hair and Skin

Training: 90 day challenge

Aquatics: Kids free training session

Your program should read this file and offer this discount:

If the service is Cafe, then discount is 1% of annual fitness club fee.

If the service is SPA, then discount is 10% of the annual fitness club fee.

If the service is Training, then discount is 15% of the annual fitness club fee.

If the service is Aquatics, then no discount, but program should only offer it for the family memberships.

Your program should ask the user what type of membership they have. Based on the type of membership, your program should calculate the dollar amount discount per service and list all applicable services and benefits for that user.

Your program should be reading the file in and calculating the benefits based on the type of membership. Your program should also randomly pick among the 4 discounts or 3 depending on the type of membership and display which discount the member gets for this month.
