The statements that are true regarding incoming and outgoing interfaces in firewall policies are:

A zone can be chosen as the outgoing interface.
-Multiple interfaces can be selected as incoming and outgoing interfaces.

<h3>What is a firewall?</h3>

A firewall is a network security device used in computing that monitors and regulates incoming and outgoing network traffic in accordance with pre-established security rules. Typically, a firewall creates a wall between a trustworthy network and an unreliable network, like the Internet.

A firewall aids in defending your network from intruders. A firewall protects your network by operating as a continuous filter that constantly scans incoming data and blocks anything that appears to be suspicious.

Therefore, the statements that are true regarding incoming and outgoing interfaces in firewall policies are:

A zone can be chosen as the outgoing interface.

-Multiple interfaces can be selected as incoming and outgoing interfaces.

Design a program that asks the user to enter a store’s sales for each day of the week. The amounts should be stored in an array.

sdas [7]

Answer:

Program given below

Explanation:

Total Sales

Assign the values of the variable as “Enter the store sales for Sunday” in Sun

Assign the values of the variable as “Enter the store sales for Monday” in Mon

Assign the values of the variable as “Enter the store sales for Tuesday” in Tue

Assign the values of the variable as “Enter the store sales for Wednesday” in Wed

Assign the values of the variable as “Enter the store sales for Thursday” in Thu

Assign the values of the variable as “Enter the store sales for Friday” in Fri

Assign the values of the variable as “Enter the store sales for Saturday” in Sat

Assign the values for the variable in array as [Sun, Mon, Tue, Wed, Thu, Fri, Sat]

Initialize tot = 0

Use the loop for calculating the total sales for the week,

for total_sales in store_sales:

tot += total_sales

then display the result as,

print "\n Total week sales = %2.f " %tot

sun = int(input("\n Enter the store sales for Sunday: "))

mon = int(input("\n Enter the store sales for Monday: "))

tue = int(input("\n Enter the store sales for Tuesday: "))

wed = int(input("\n Enter the store sales for Wednesday: "))

thu = int(input("\n Enter the store sales for Thursday: "))

fri = int(input("\n Enter the store sales for Friday: "))

sat = int(input("\n Enter the store sales for Saturday: "))

store_sales = [sun, mon, tue, wed, thu, fri, sat]

tot = 0

for store_sale in store_sales:

tot += store_sale

print "\n Total Week Sales: %2.f" %tot

We will have the following output:

OUTPUT 

 Enter the store sales for Sunday: 45

Enter the store sales for Monday: 56

Enter the store sales for Tuesday: 89

Enter the store sales for Wednesday:78

Enter the store sales for Thursday: 45

Enter the store sales for Friday: 12

Enter the store sales for Saturday: 23

Total Week Sales: 348

write a C program the prints out the size of variables with the following C data types- int, long, unsigned, long long, double,

Anit [1.1K]

C program for finding size of different data types

#include <stdio.h>

//driver function

int main()

{

int a; //declaring a of type int

float b; //declaring b of type float

double c; //declaring c of type double

char d; //declaring d of type char

long e; //declaring e of type long

long long f; //declaring f of type longlong

unsigned g; //declaring g of type unsigned

// Sizeof operator is used to evaluate the size of a variable

printf(" int data type contains: %lu bytes\n",sizeof(a));/*Finding size of int */

printf("float data type contains : %lu bytes\n",sizeof(b));/*Finding size of float */

printf("double data type contains: %lu bytes\n",sizeof(c));/*Finding size of double */

printf("char data type contains: %lu byte\n",sizeof(d));/*Finding size of char */

printf("long data type contains: %lu byte\n",sizeof(e));/*Finding size of long*/ printf("longlong data type contains: %lu byte\n",sizeof(f));/*Finding size of longlong */

printf("unsigned data type contains: %lu byte\n",sizeof(g)); /*Finding size of unsigned */

return 0;

}

Output

int data type contains: 4 bytes

float data type contains : 4 bytes

double data type contains: 8 bytes

char data type contains: 1 byte

long data type contains: 8 byte

longlong data type contains: 8 byte

unsigned data type contains: 4 byte

A personal identification number (PIN) that opens a certain lock consists of a sequence of 3 different digits from 0 through 9,

Elan Coil [88]

Answer:

720 possible PIN can be generated.

Explanation:

To calculate different number of orders of digits to create password and PIN, we calculate permutation.

Permutation is a term that means the number of methods or ways in which different numbers, alphabets, characters and objects can arranged or organized. To calculate the permutation following formula will be used:

nPr = n!/(n-r)!

there P is permutation, n is number of digits that need to be organize, r is the size of subset (Number of digits a password contains)

So in question we need to calculate

P=?

where

n= 10 (0-9 means total 10 digits)

r= 3 (PIN Consist of three digits)

So by using formula

10P3 = 10!/(10-3)!

=10!/7!

= 10x9x8x7!/7!

= 10x9x8

= 720
