Write a section of code to simulate the opening coin toss of a football game. The visiting team gets to choose heads or tails. If the team guesses correctly they get to choose to kick or receive. Otherwise the home team gets the same choice. Display the final result of the coin flip in form similar to below
Possibly output "home team has won the toss"
"Home team has chosen to kick first"
Or "visting team has won the toss"
"Visiting team has chosen to receive first"
Answer:
Explanation:
Which goal his team will defend: Instead of receiving the kickoff, the captain may elect to kick off and choose a goal to defend. Captains sometimes take this option if they believe that weather will be a factor in the outcome of the game. For example, in choosing which goal to defend, the player believes that his team will have the wind at its back for the second quarter and the crucial final quarter of the game.

Answer:
Here is the corrected code:
import java.util.*;
public class DebugNine36 { //class name
public static void main(String[] args) { //start of main method
ArrayList<String>products = new ArrayList<String>(); //creates an ArrayList of type String names products
products.add("shampoo"); //add shampoo to product array list
products.add("moisturizer"); //add moisturizer product array list
products.add("conditioner"); //add conditioner product array list
Collections.sort(products); //sort the elements in products array list
display(products); //calls display method by passing products array list
final String QUIT = "quit"; //declares a variable to quit the program
String entry; //declares a variable to hold product/element or quit
Scanner input = new Scanner(System.in); //creates Scanner object
System.out.print("\nEnter a product or " + QUIT + " to quit >> "); //prompts user to enter a product or enter quit to exit
entry = input.nextLine(); //reads the entry value from user
while(!entry.equals("quit")) { //loops until user enters quit
products.add(entry); //adds entry (product) to products array list
Collections.sort(products); //sorts the elements in products array list
display(products); //calls display method by passing products arraylist
System.out.print("\nEnter a product or " + QUIT + " to quit >> "); //keeps prompting user to enter a product or enter quit to exit
entry = input.nextLine(); } } //reads the entry value from user
public static void display(ArrayList products) { // method to display the list of products
System.out.println("\nThe size of the list is " + products.size()); //displays the size of the array list named products
for(int x = 0; x < products.size(); ++x) //iterates through the arraylist products
System.out.println(products.get(x)); } } //displays each item/element in products array list
Explanation:
In the code the following statement are corrected:
1.
ArrayListproducts = new ArrayList();
This gave an error: cannot find symbol
This is corrected to :
ArrayList<String>products = new ArrayList<String>();
2.
products.add(shampoo);
products.add(moisturizer);
products.add(conditioner);
Here shampoo moisturizer and conditioner are String type items that are to be added to the products so these strings have to be enclosed in quotation marks.
This is corrected to :
products.add("shampoo");
products.add("moisturizer");
products.add("conditioner");
3.
display();
This method is called without giving any arguments to this method. The method display takes an ArrayList as argument so it should be passed the arraylist products to avoid error that actual and formal argument lists differ in length .
This is corrected to :
display(products);

This program outputs a downwards facing arrow composed of a rectangle and a right triangle. The arrow dimensions are defined by user specified arrow base height, arrow base width, and arrow head width. #include int main(void) {int arrowBaseHeight = 0;int arrowBaseWidth = 0;int arrowHeadWidth = 0;printf("Enter arrow base height:\n");scanf("%d", &arrowBaseHeight);printf("Enter arrow base width:\n");scanf("%d", &arrowBaseWidth);printf("Enter arrow head width:\n");scanf("%d", &arrowHeadWidth);printf("\n");// Draw arrow base (height = 3, width = 2)printf( "**\n");printf( "**\n");printf( "**\n");// Draw arrow head (width = 4)printf( "****\n");printf( "***\n");printf( "**\n");printf( "*\n");return 0;}a. Modify the given program to use a loop to output an arrow base of height arrow_base_height. b. Modify the given program to use a loop to output an arrow base of width arrow_base_width.c. Modify the given program to use a loop to output an arrow head of width arrow_head_width.
Answer:
Here is the C program:
#include <stdio.h> //to use input output functions
int main(void) { //start of main function
int arrowBaseHeight = 0; //stores value for arrow base height
int arrowBaseWidth = 0; //stores value for arrow base width
int arrowHeadWidth = 0 ; //stores value for arrow head width
int i, j; //to traverse through the rows and columns
printf("Enter arrow base height:\n"); //prompts user to enter arrow base height value
scanf("%d", &arrowBaseHeight); //reads input value of arrow base height
printf("Enter arrow base width:\n"); //prompts user to enter arrow base width value
scanf("%d", &arrowBaseWidth); //reads input value of arrow base width
while (arrowHeadWidth <= arrowBaseWidth) { //iterates as long as the value of arrowHeadWidth is less than or equals to the value of arrowBaseWidth
printf("Enter arrow head width:\n"); //prompts user to enter arrow head width value
scanf("%d", &arrowHeadWidth); //reads input value of arrow head width
printf("\n"); }
for (i = 0; i < arrowBaseHeight; i++) { //iterates through rows
for (j = 0; j < arrowBaseWidth; j++) { //iterates through columns
printf("*"); } //prints asterisks
printf("\n"); } //prints a new line
for (i = arrowHeadWidth; i > 0; i--) { //loop for input length
for (j = i; j > 0; j--) { //iterates for triangle ( to make arrow head)
printf("*"); } //prints asterisks
printf("\n"); } } //prints new line
Explanation:
The program asks to enter the height of the arrow base, width of the arrow base and the width of arrow head. When asking to enter the width of the arrow head, a condition is checked that the arrow head width arrowHeadWidth should be less than or equal to width of arrow base arrowBaseWidth. The while loop keeps iterating until the user enters the arrow head width larger than the value of arrow base width.
The loop is used to output an arrow base of height arrowBaseHeight.
The nested loop is being used which as a whole outputs an arrow base of width arrowBaseWidth. The inner loop draws the stars and forms the base width of the arrow, and the outer loop iterates a number of times equal to the height of the arrow.
The last nested loop is used to output an arrow head of width arrowHeadWidth. The inner loop forms the arrow head and prints the stars needed to form an arrow head.
The screenshot of output is attached.

A. Google Adwords B. Technorati search C. Bing Ads D. Radian6
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is Google Adwords and Bing Ads.
First we need to know what is CPC and PPC.
Cost per click (CPC) is a paid advertising term used by Google where an advertiser pays a cost to the publisher for every click when an internet user will click on the advertisement or ad.
Cost per click is also called PPC (Pay per click). CPC is used to determine the costs of showing advertisements on the search engine, for example Google Adwords and Bing Ads. Bing Ads is microsoft advertising strategy on internet using PPC advertising strategy.
While other options are not correct because:
technorati search does not allow you to apply these concepts because it searches the list of blogs on the internet.

You have a large text file of people. Each person is represented by one line in the text file. The line starts with their ID number and after that, has the person's name. The lines are sorted by ID number in ascending order. There are n lines in this file. You write a search function that returns the name of a person whose ID number is given The simplest way to do that would be to program a loop that goes through each line and compares the ID number in the line against the given ID number. If there is a match, then it returns the name in that line. This is very inefficient, because the worst-case scenario is that this program needs to go through almost everyone the person we are looking for could be last. using the fact that he tli s sored wil greany speed up the processbus to use a birarysearch alkrhm We go to the middle line of the file first and compare the ID found there (P) to the given ID (Q). (f the number of lines is even, we go above or below the arithmetic middle.) if P=Q then our algorithm terminates . we have found the person we are looking for. If P is less than Q, that means that the person we are looking for is in the second half of the file. We now repeat our algorithm on the second half of the file. If P is greater than Q, that means that the person we are looking for is in the first half of the file. We now repeat our algorithm on the first half of the file.

Summary: Given integer values for red, green, and blue, subtract the gray from each value.
Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray).
Given values for red, green, and blue, remove the gray part.
Ex: If the input is:
130 50 130
the output is:
80 0 80
Find the smallest value, and then subtract it from all three values, thus removing the gray

public class LabProgram{
public static void main(String []args){
Scanner input = new Scanner(System.in);
int red,blue,green,smallest;
System.out.print("Enter three numbers between 0 and 255 (inclusive): ");
red =input.nextInt();
green =input.nextInt();
blue =input.nextInt();
if(red <= blue && red <= green){
smallest = red;
}
else if(green <= red && green <= blue){
smallest = green;
}
else{
smallest = blue;
}
System.out.print((red - smallest)+" "+(green - smallest)+" "+(blue - smallest));
}
}
Explanation:
This line declares necessary variables
int red,blue,green,smallest;
This line prompts user for input of 3 numbers
System.out.print("Enter three numbers between 0 and 255 (inclusive): ");
The next three lines gets user inputs
red =input.nextInt();
green =input.nextInt();
blue =input.nextInt();
The following iteration checks for the smallest for red, green, blue
if(red <= blue && red <= green){
smallest = red;
}
else if(green <= red && green <= blue){
smallest = green;
}
else{
smallest = blue;
}
This line prints the required output
System.out.print((red - smallest)+" "+(green - smallest)+" "+(blue - smallest));

12.18 Lab - Structs
In this lab, you will familiarize yourself with structs through a small exercise. We will be mixing the RGB values of colors together to make a new one.
RGB stands for red, green and blue. Each element describes the intensity value ranging from 0 - 255. For example: black color will have RGB values (0, 0, 0) while white will have (255, 255, 255).
Create an array of structs color. The struct contains three integers named red, green and blue. This corresponds to the RGB values of a color. For each array element, ask the user to enter the intensity value of red, green and blue. The value should be between 0 and 255 (inclusive).
*********The user can enter at most 10 colors. ********. see below for inputs
Additionally, compute the average of each of the red, green and blue components. For code modularity, implement a function that returns the average of each rgb component in your dynamic array. The function (called average) should take in a struct array, the rgb type for which you want to compute the average (as a string - red, blue or green) and its length. Print out the final result in the form (r, g, b), where r, g, b corresponds to each averaged value.
Can you guess what color you mixed? (Note: Your program does not need to print the final color mixed)
