Write a program named as calcPrice.c that formats product information entered by the user and calculate the total amount of purchase.
Answer:
Here is the calcPrice.c program:
#include <stdio.h> //to use input output functions
int main(void) { //start of main method
int itemNo, month, day, year, quantity; //declares variables to hold item number, quantity, and date
float unitPrice; //declare variable to hold price per unit
printf("Enter item number: "); // prompts user to enter item number
scanf("%d", &itemNo); //reads item number from user and stores it in itemNo variable
printf("Enter unit price: "); // prompts user to enter unit price
scanf("%f", &unitPrice); //reads input unit price and stores it in unitPrice variable
printf("Enter quantity: "); //prompts user to enter quantity
scanf("%d", &quantity); //reads input quantity and stores it in quantity variable
printf("Enter purchase date (mm/dd/yyyy): "); //prompts user to enter purchase date
scanf("%d/%d/%d", &month, &day, &year); //reads input date and stores it in month, day and year variables
float totalAmount = unitPrice * quantity; //computes the total amount
printf("\nItem\tUnit Price\tQTY\tPurchase Date\tTotal Amount\n"); //displays the item, unit price, qty, purchase data and total amount with tab space between each
printf("%d\t$%5.2f\t%d\t%.2d/%.2d/%d\t$%5.2f\n", itemNo, unitPrice,quantity, month, day, year,totalAmount); } //displays the values of itemNo, unitPrice, quantity, month, day, year and computed totalAmount with tab space between each
Explanation:
Lets suppose user enters 583 as item number, 13.5 as unit price, 2 as quantity and 09/15/2016 as date so
itemNo = 583
unitPrice = 13.5
quantity = 2
month = 09
day = 15
year = 2016
totalAmount is computed as:
totalAmount = unitPrice * quantity;
totalAmount = 13.5* 2
totalAmount = 27.00
Hence the output of the entire program is:
Item Unit Price QTY Purchase Date Total Amount
583 $ 13.50 2 09/15/2016 $ 27.00

What is an example of a condition controlled loop? What would the syntax look like?
Answer:
The answer to this question is given below in the explanation section.
Explanation:
WHILE loops and DO WHILE loops are called the condition controlled loops. The execution of these loops depends on a certain condition, when the condition is true, the loop body will be executed and when the condition becomes false, the loop body will not be executed. the major difference between both loops is given below.
In the WHILE loop, the condition is checked at the beginning of the loop whereas in the do-while loop condition is checked at the end of the loop and, in the do-while loop, the loop body is executed at least once.
The syntax of the while loop is given below
while (condition) {
// code block to be executed
}
The syntax of do-while loop is given below
do {
// code block to be executed
}

Answer: 40, 4
Explanation:
You have been given two classes, a Main.java and a Coin.java. The coin class represents a coin. Any object made from it will have a 1) name, 2) weight and 3) value. As of now, the instance variables in Coin.java are all public, and the main function is calling these variables directly for the one coin made in it.
Required:
Your goal is to enforce information hiding principles in this tasl. Take Coin.java, make all instance variables private and create set/get functions for each instance variable. Then replace the direct references in main() to each instance variable with a call to an appropriate set or get function.
Answer:
Here is the Coin class:
public class Coin { //class names
private int value; // private member variable of type int of class Coin to store the value
private String coinName; // private member variable of type String of class Coin to store the coint name
private double weight; //private member variable of type double of class Coin to store the weight
public void setValue (int v) { //mutator method to set the value field
value = v; }
public void setName(String n){ //mutator method to set coinName field
coinName = n;}
public void setWeight (double w) { //mutator method to set weight field
weight = w; }
public int getValue () { //accessor method to get the value
return value; } // returns the current value
public String getName () { //accessor method to get the coin name
return coinName; } //returns the current coin name
public double getWeight () { //accessor method to get the weight
return weight; } } //returns the current weight
Explanation:
Here is the Main.java
public class Main{ //class name
public static void main(String[] args) { //start of main method
Coin penny = new Coin(); //creates object of Coin class called penny
penny.setName("Penny"); //calls setName method of Coin using object penny to set the coinName to Penny
penny.setValue(1); //calls setValue method of Coin using object penny to set the coin value to 1
penny.setWeight(0.003); //calls setWeight method of Coin using object penny to set the coin weight to 0.003
System.out.println("Coin name: " + penny.getName()); // calls getName method of Coin using penny object to get the current coin name stored in coinName field
System.out.println("Coin value: " + penny.getValue()); // calls getValue method of Coin using penny object to get the coin value stored in value field
System.out.println("Coin weight: " +penny.getWeight()); }} // calls getWeight method of Coin using penny object to get the coin weight stored in weight field
The value of coinName is set to Penny, that of value is set to 1 and that of weight is set to 0.003 using mutator method and then the accessor methods to access these values and prinln() to display these accessed values on output screen. Hence the output of the entire program is:
Coin name: Penny Coin value: 1 Coin weight: 0.003
The screenshot of the program along with its output is attached.

802.11ac provides an advantage over 802.11n by incorporating increased channel bonding capabilities. What size bonded channels does 802.11ac support?
Answer:
The 802.11ac wireless standard takes channel bonding to a higher level because it can support 20MHz, 40MHz, and 80MHz channels, with an optional use of 160MHz channels.
Explanation:
The 802.11ac is a standardized wireless protocol established and accepted by the institute of electrical and electronics engineers (IEEE). 802.11ac as a wireless local area network (WLAN) protocol, has multiple amplitude and bandwidth, thus making it to be the first standard wireless protocol to have the ability to operate on a Gigabit (Gb) network.
Generally, the 802.11ac wireless standard provides an advantage over 802.11n by incorporating increased channel bonding capabilities. The 802.11ac wireless standard takes channel bonding to a higher level because it can support 20MHz, 40MHz, and 80MHz channels, with an optional use of 160MHz channels.
On the other hand, 802.11n is a standardized wireless protocol that can support either a 20MHz or 40MHz channel.
Consider a Stop-and-Wait protocol. Assume constant delays for all transmissions and the same delay for packets sent and ACKs sent. Assume no errors occur during transmission.
(a) Suppose that the timeout value is set to 1/2 of what is required to receive an acknowledgement, from the time a packet is sent. Give the complete sequence of frame exchanges when the sender has 3 frames to send to the receiver.
(b) Suppose that the timeout value is sent to 2 times the round trip time. Give the sequence of frame exchanges when 3 frames are sent but the first frame is lost.
Explanation:
question a) answer:
At the moment when it sends the package, then it has a waiting time for the acknowledgement from the receiver, however, the time will be split in two when the frameset size becomes two, meaning that two packages have been sent together, causing the receiver to acknowledge only one package.
question b) answer:
The timeout is equal to two times.
In cases when the frame size is 3, the frame will be lost since the timeout turns to be 2 times. Because the sender has to wait for the acknowledgement, therefore it will send other of the parcels.

/*To access the interface Runner method run(), the Runner must be "implemented" by Machine, Athlete, and PoliticalCandidate classes with the implements keyword. The body of the interface method run() is provided by the "implement" class */
Here is the DemoRunners class:
public class DemoRunners { //class name
public static void main(String[] args) { //start of main method
Machine runner1 = new Machine(); //creates object of Machine class
Athlete runner2 = new Athlete(); //creates object of Athlete class
PoliticalCandidate runner3 = new PoliticalCandidate(); //creates object of PoliticalCandidate class
runner1.run(); //uses object of Machine class to call run method
runner2.run(); //uses object of Athlete class to call run method
runner3.run(); } } //uses object of PoliticalCandidate class to call run method
When runner1.run() is called it invokes the run() method of class Machine which displays the message:
When a machine is running, it is operating.
When runner2.run() is called it invokes the run() method of class Athlete which displays the message:
An athlete might run in a race, or in a game like soccer.
When runner3.run() is called it invokes the run() method of class PoliticalCandidate which displays the message:
A political candidate runs for office.

Wrire a code that display elements at indices 1 and 4 in the follwoing array.
var userArray = [1, 6, 41, 8, 24, 4];
Answer:
Console.log(userArray[1]);
Console.log(userArray[4]);
Explanation:
The programming language was not stated; however, the variable declaration implies JavaScript.
JavaScript prints using the following syntax:
Console.log(print-name);
Since, the code is to print some elements of array userArray.
First, we need to determine the index of the elements.
The indices are given as 1 and 4.
So, the code to print these elements is as follows:
Console.log(userArray[1]);
Console.log(userArray[4]);
