Answer:

To create a public key signature, you would use the _private_ key.

Explanation:

To create a public key signature, a  private key is essential to enable authorization.

A private key uses one key to make data unreadable by intruders and for the data to be accessed the same key would be needed to do so.

The login details and some important credentials to access user data contains both the user's public key data and private key data. Both private key and public key are two keys that work together to accomplish security goals.

The public key uses different keys to make data readable and unreadable.

The public key is important to verify authorization to access encrypted data by making sure the access authorization came from someone who has the private key. In other words, it's a system put in place to cross-check the holder of the private key by providing the public key of the encrypted data that needed to be accessed. Though, it depends on the key used to encrypt the data as data encrypted with a public key would require a private key for the data to be readable.

The correct answer would BE (puns) B. They are limited to 256 colors

The statement that is true regarding GIF is that they are limited to 256 colors. The correct option is B.

GIF (graphics interchange format) is a digital file format invented in 1987 by Internet service provider CompuServe to reduce the size of images and short animations.

GIFs are short animations and video clips. GIFs are frequently used to represent a feeling or action.

LZW compression is used in the GIF format, which is a lossless compression method.

However, because GIF files are limited to 256 colors, optimizing a 24bit image as an 8bit GIF can result in color loss. GIF is a raster data format originally developed for simple images that are commonly found on the internet.

In a browser, you can control how colors dither and choose the number of colors in a GIF image.

Thus, the correct option is B.

Answer:

D. all of the above

Explanation:

A option is correct and function definition must be written before they are called by another part of your program. But in languages such as C++ you can write the prototype of the function before it is called anywhere in the program and later write the complete function implementation. I will give an example in Python:

def addition(a,b): #this is the definition of function addition

    c = a + b

    return c    

print(addition(1,3)) #this is where the function is called

B option is correct and function definition must declare a name for the function. If you see the above given function, its name is declared as addition

C option is correct and function definition must include information regarding any arguments (if any) that will be passed to the function. In the above given example the arguments are a and b. If we define the above function in C++ it becomes: int addition( int a, int b)

This gives information that the two variables a and b that are parameters of the function addition are of type int so they can hold integer values only.

Hence option D is the correct answer. All of the above options are correct.

while num < 1:

    num = int(input("Number: "))

total = 0

for i in range(1, num+1):

    total= total + i

print("Total: "+str(total))

Explanation:

This line prompts user for input

num = int(input("Number: "))

The following iteration checks and prompts user for valid input

while num < 1:

    num = int(input("Number: "))

This initializes total to 0

total = 0

The following iteration adds from 1 to input number

   output = base ** i

   while limit >= output:

       outputlist.append(output)

       i = i + 1

       output = base ** i

   return(outputlist)

Explanation:

This declares the function

def powerss(base, limit):

This creates an empty list for the output list

   outputlist = []

This initializes a counter variable i to 1

   i = 0

This calculates base^0

   output = base ** i

The following iteration checks if limit has not be reached

   while limit >= output:

This appends items to the list

       outputlist.append(output)

The counter i is increased here

       i = i + 1

This calculates elements of the list

       output = base ** i

This returns the output list

Answer:

Here is the C program. Let me know if you want the program in some other programming language.

#include <stdio.h>   //to use input output functions

int main() {   //start of main function

int num;   // to store input numbers

int sum = 0;  //to store the sum of numbers

scanf("%d", &num);   //reads the numbers from user

int count = 0;   //to count the total numbers entered by user

int max = 0;   //to store the maximum of numbers

while(num >= 0)  {  //continues to execute until user enters negative number

sum+=num;   //adds the numbers

scanf("%d", &num);   //reads the numbers from user

count++;   //counts the numbers entered

if(num>=max){    //if number is greater than numbers stored in max

 max = num;   }   }  //assigns that maximum number to max

   printf("%d %d", sum/count,max);  }  //displays the average of numbers and maximum of numbers

Explanation:

I will explain the program with an example. Lets say the first number input by user is 15. Then the loop works as follows:

At first iteration:

num >= 0 is true because 15 is greater than 0 so program moves to the body of loop

sum+=num; becomes:

sum = sum + num

sum = 0 + 15

sum = 15

count++; becomes:

count = count + 1

count = 0 + 1

count = 1

if(num>=max) means if(15>=0) this is true so

 max = num;  this becomes:

max = 15

Lets say the next value entered by user is 20. It is stored in num variable

At second iteration:

num >= 0 is true because 20 is greater than 0 so program moves to the body of loop

sum+=num; becomes:

sum = sum + num

sum = 15 + 20

sum = 35

count++; becomes:

count = count + 1

count = 1 + 1

count = 2

if(num>=max) means if(20>=15) this is true so

 max = num;  this becomes:

max = 20

Lets say the next value entered by user is 0. It is stored in num variable

At third iteration:

num >= 0 is true because 0 is equal to 0 so program moves to the body of loop

sum+=num; becomes:

sum = 35 + num

sum = 35 + 0

sum = 35

count++; becomes:

count = count + 1

count = 2 + 1

count = 3

if(num>=max) means if(0>=20) this is false so

 max = num;  this remains:

max = 20

Lets say the next value entered by user is 5. It is stored in num variable

At fourth iteration:

num >= 0 is true because 5 is greater than 0 so program moves to the body of loop

sum+=num; becomes:

sum = 35 + 5

sum = 35 + 5

sum = 40

count++; becomes:

count = count + 1

count = 3 + 1

count = 4

if(num>=max) means if(5>=20) this is false so

 max = num;  this remains:

max = 20

Lets say the next value entered by user is -1. It is stored in num variable

Now the loop breaks because num >= 0 is false because -1 is less than 0 so program moves to the statement:

printf("%d %d", sum/count,max);

This has two parts to print on output screen:

sum/count which is 40/4 = 10

max which is 20

So the output of the entire program is:

10  20

The screenshot of program along with its output is attached.

The program that takes any number of non-negative integers as input, and outputs the average and max is coded below.

The program written in Python that takes non-negative integers as input, calculates the average and maximum, and stops when a negative integer is encountered:

numbers = []

num_sum = 0

max_num = float('-inf')

while True:

   num = int(input("Enter a non-negative integer (enter a negative integer to stop): "))

   if num < 0:

       break

   numbers.append(num)

   num_sum += num

   max_num = max(max_num, num)

if len(numbers) > 0:

   average = num_sum / len(numbers)

   print("Average:", average)

   print("Max:", max_num)

else:

   print("No non-negative integers were entered.")

In this program, we start by initializing an empty list `numbers` to store the non-negative integers.

We also initialize variables `num_sum` to keep track of the sum of the numbers and `max_num` to track the maximum number encountered.

We then use a while loop that continues until a negative integer is entered. Inside the loop, we prompt the user to enter a non-negative integer. If the number is negative, the loop is terminated using the `break` statement. Otherwise, we append the number to the `numbers` list, update the sum `num_sum`, and check if it is greater than the current `max_num`.

After exiting the loop, we calculate the average by dividing the sum by the number of elements in the `numbers` list (which is obtained using the `len()` function). Finally, we print the average and the maximum value.

Explanation:

Answer:

Avoid dirt and sand. Use care when cleaning dirt particles and sand from your digital camera. Do not use canned or pressurized air to clean the sand, as you might just drive the particles into the camera case. Budget-priced camera cases might not be sealed perfectly, making it easier for grit and sand to penetrate the case and cause damage. Gently blow out the grit and sand to avoid this problem. Use care when shooting photos on a windy day at the beach, too, where sand can blow with excessive force. Avoid opening the battery compartment on such days.

Avoid liquids. Keep all liquids away from the camera unless you own a model with a waterproof case.

Avoid touching the lens and LCD. Oils from your skin smudge the lens and LCD, eventually causing permanent damage. Clean the lens and LCD with a microfiber cloth when you see a smudge from your fingertips.

The lens and sun don't mix. Do not point your camera's lens directly at the sun for any length of time, especially with a DSLR camera. Sunlight focused through the lens of the camera could damage the image sensor or even start a fire inside the camera.

Use cleaning liquids with care. Avoid using an excessive amount of cleaning liquid with your camera. In fact, other than stubborn smudges, you should be able to clean the camera with a dry microfiber cloth. If a liquid is needed, place a few drops of the liquid on the cloth, rather than directly on the camera.

Vacuum the bag. Dirt and sand inside your camera bag could damage your camera, so vacuum the bag regularly to keep it clean and protect your camera.

Watch the temperature. Although some cameras are designed to survive harsh temperatures, most cameras are not. Do not leave your camera in a sunny vehicle, where temperatures quickly can exceed 100 degrees Fahrenheit. Avoid leaving the camera in direct sunlight, which can damage the plastic. Finally, avoid extreme cold, too, which could damage the LCD.

Use neck straps and wrist loops. Use neck straps and wrist loops with your camera. If you slip while hiking, or if you lose the grip on your camera near the pool, the straps can save your camera from a potentially disastrous fall.

Store camera properly. If you're not going to use your camera for a couple of months, store it in a low humidity area and out of direct sunlight. Additionally, store the camera without the battery inserted to reduce the risk of corrosion.
