ahrayia [7]

Answer:

Here is the JAVA program:

public class Main { //class name

public static void main(String[] args) { //start of main method

//sets all boolean type variables spades, hearts diamonds and clubs to false initially

boolean spades = false;

boolean hearts = false;

boolean diamonds = false;

boolean clubs = false;

String[] deck = new String[4]; //to store card sequence

int index = 0; //to store index position

int NoOfPicks = 0; //to store number of picks (picks count)

while (!spades || !hearts || !diamonds || !clubs) { //loop starts

String card = printCard(getRandomCard()); //calls printCard method by passing getRandomCard method as argument to it to get the card

NoOfPicks++; //adds 1 to pick count

if (card.contains("Spades") && !spades) { //if that random card is a card of Spades and spades is not false

deck[index++] = card; //add that card to the index position of deck

spades = true; //sets spades to true

} else if (card.contains("Hearts") && !hearts) { //if that random card is a card of Hearts and hearts is not false

deck[index++] = card;

hearts = true; //sets hearts to true

} else if (card.contains("Diamond") && !diamonds) { //if that random card is a card of Diamond and diamonds is not false

deck[index++] = card;

diamonds = true; //sets diamonds to true

} else if (card.contains("Clubs") && !clubs) { if that random card is a card of Clubs and clubs is not false

deck[index++] = card;

clubs = true; } } //sets clubs to true

for (int i = 0; i < deck.length; i++) { //iterates through the deck i.e. card sequence array

System.out.println(deck[i]); } //prints the card number in deck

System.out.println("Number of picks: " + NoOfPicks); } //prints number of picks

public static int getRandomCard() { //gets random card

return (int) (Math.random() * 52); } //generates random numbers of 52 range

public static String printCard(int cardNo) { //displays rank number and suit

String[] suits = { "Spades", "Hearts", "Diamonds", "Clubs", }; //array of suits

String[] rankCards = { "Ace", "2", "3", "4", "5", "6", "7", "8", "9", "10",

"Jack", "Queen", "King" }; //array of rank

int suitNo = cardNo / 13; //divides card number by 13 and stores to suitNo

int rankNo = cardNo % 13; //takes modulo of card number and 13 and store it to rankNo

return rankCards[rankNo] + " of " + suits[suitNo]; }} //returns rankCard at rankNo index and suits at suitNo index

Valentin [98]

Answer:

False

Explanation:

A Domain Based Security. "Domain Based Security", abbreviated to "DBSy", is a model-based approach that is being used in analyzing information security risks in a business context and offers an apparent, understandable and direct mapping among the risks and the security controls needed to handle them.

While A security domain is the list of items a subject is permitted to access. More largely defined, domains are collections of subjects and objects with related security requirements.

Using the program below, explain what the output will be at LINE A. 1 #include 2#include 3#include 4 5 int value - 128; 6 7 int

slega [8]

Answer:

This is the complete correct program:

#include <stdio.h>

#include<sys/types.h>

#include<unistd.h>

int value = 128;

int main()

{

pid_t pid;

pid=fork();

if (pid==0) /* child process */

{

value +=8;

return 0; }

else if (pid > 0) {/* parent process */

wait (NULL);

printf ("PARENT: value =%d\n" ,value); /* LINEA */

return 0;

}

The output of the LINE A is:

PARENT: value = 128

Explanation:

The fork() function used in the program creates a new process and this process is the child process. The child process is same as the original process having its own address space or memory.

In the child process the value of pid is 0. So the if condition checks if pid==0. Then the child process adds 8 to the value of its variable according to the following statement

value +=8;

Now the original process has value = 128. In else if part the parents process has the value of pid greater than zero and this portion of the program is of the parent process :

else if (pid > 0)

{ wait (NULL);

printf ("PARENT: value =%d\n" ,value);

return 0; }

So the value 128 is printed at the end in the output.

wait(NULL) is used to wait for the child process to terminate so the parent process waits untill child process completes.

So the conclusion is that even if the value of the variable pid is changed in the child process but it will not affect the value in the variable of the parent process.

Ask the user for a total food bill and then find the new total after 6% tax and a tip of the users choice (15, 18, 20%) in pytho

chubhunter [2.5K]

Answer:

#here is code in python.

# read the food bill

tot_bill=float(input("Please enter the food bill:"))

# tax on food

tax=0.06

#choice for tip by user

choice=int(input("enter your choice for tip:(1 for 15%, 2 for 18% and 3 for 20% :)"))

// calculate the total food bill

if choice==1:

tot_food_bill=tot_bill+tot_bill*tax+tot_bill*(.15)

elif choice==2:

tot_food_bill=tot_bill+tot_bill*tax+tot_bill*(.18)

elif choice==3:

tot_food_bill=tot_bill+tot_bill*tax+tot_bill*(.2)

else:

print("invalid choice:")

#print the total food bill

print("total food bill is ",tot_food_bill)

Explanation:

Read the food bill from user and assign it to variable "tot_bill".Initialize the tax=0.06 (i.e. 6%) on the bill.Then ask user to give his choice for tip. if the choice is 1 then tip will be 15%, if 2 then 18% and if choice is 3 Then tip will be 20% of the bill.Calculate the total food bill and assign it to variable "tot_food_bill".

Output:

Please enter the food bill:100

enter your choice for tip:(1 for 15%, 2 for 18% and 3 for 20% :)2

total food bill is 124.0
