You are the network administrator for your company. A user reports that he cannot access network resources from his computer. He was able to access the resources yesterday. While troubleshooting his computer, you find that his computer is issued an Automatic Private IP Addressing (APIPA) address. All the network equipment in the user's computer is functioning properly because you are able to access the user's computer from a remote computer. What is most likely the problem
Answer:
the issued Automatic Private IP Addressing (APIPA) address.
Explanation:
Since we are told that the user was able to access the network resources yesterday, and all the network equipment in the user's computer is functioning properly, there is a very high possibility that because the user's computer has been issued an Automatic Private IP Addressing (APIPA) address, it affected his computer's ability to connect to a public network.
This is the case because private network IP addresses are known to prevent inflow and outflow of data onto public networks.

Assume the existence of a Phone class. Define a derived class, CameraPhone that contains two data members: an integer named, imageSize, representing the size in megabytes of each picture, and an integer named memorySize, representing the number of megabytes in the camera's memory. There is a constructor that accepts two integer parameters corresponding to the above two data members and which are used to initialize the respective data members. There is also a function named numPictures that returns (as an integer) the number of pictures the camera's memory can hold.
#include <iostream>
using namespace std;
class CameraPhone:Phone{
int imageSize,memorySize;
public:
CameraPhone(int image_size,int memory_size):imageSize(image_size),memorySize(memory_size){}
int numPictures(){
return memorySize-imageSize;
}
}
int main(){}
Here is the code for the derived class, CameraPhone:
class Phone:
def __init__(self, brand, model, price): self.brand = brand self.model = model self.price = priceclass CameraPhone(Phone):
def __init__(self, brand, model, price, imageSize, memorySize): super().__init__(brand, model, price) self.imageSize = imageSize self.memorySize = memorySizedef numPictures(self):
return self.memorySize // self.imageSizeWhat are the derived class?This code defines a derived class, CameraPhone, that inherits from the Phone class. The CameraPhone class has two additional data members: imageSize and memorySize. The constructor for the CameraPhone class takes two additional parameters corresponding to these data members. The numPictures() function returns the number of pictures that the camera's memory can hold.
Here is an example of how to use the CameraPhone class:
phone = CameraPhone("Apple", "iPhone 13 Pro", 1000, 10, 100)
print(phone.numPictures())
# Output: 10
This code will print the number of pictures that the camera's memory can hold, which is 10 in this case.

how do you run a function in python?
Complete the function to replace any period by an exclamation point. Ex: "Hello. I'm Miley. Nice to meet you." becomes:
"Hello! I'm Miley! Nice to meet you!"
#include
#include
using namespace std;
void MakeSentenceExcited(char* sentenceText) {
/* Your solution goes here */
}
int main() {
const int TEST_STR_SIZE = 50;
char testStr[TEST_STR_SIZE];
strcpy(testStr, "Hello. I'm Miley. Nice to meet you.");
MakeSentenceExcited(testStr);
cout << testStr << endl;
return 0;
}
Answer:
Here is the complete function:
void MakeSentenceExcited(char* sentenceText) { // function that takes the text as parameter and replaces any period by an exclamation point in that text
int size = strlen(sentenceText); //returns the length of sentenceText string and assigns it to size variable
char * ptr; // character type pointer ptr
ptr = sentenceText; // ptr points to the sentenceText string
for (int i=0; i<size; i++){ //iterates through the sentenceText string using i as an index
if (sentenceText[i]=='.'){ // if the character at i-th index of sentenceText is a period
sentenceText[i]='!'; } } } //places exclamation mark when it finds a period at i-th index of sentenceText
Explanation:
The program works as follows:
Suppose we have the string:
sentenceText = "Hello. I'm Miley. Nice to meet you."
The MakeSentenceExcited method takes this sentenceText as parameter
int size = strlen(sentenceText) this returns the length of sentenceText
The size of sentenceText is 35 as this string contains 35 characters
size = 35
Then a pointer ptr is declared which is set to point to sentenceText
for (int i=0; i<size; i++) loop works as follows:
1st iteration:
i=0
i<size is true because i=0 and size = 35 so 0<35
So the body of loop executes:
if (sentenceText[i]=='.') statement checks :
if (sentenceText[0]=='.')
The first element of sentenceText is H
H is not a period sign so the statement inside if statement does not execute and value of i increments to 1. Now i = 1
2nd iteration:
i=1
i<size is true because i=1 and size = 35 so 1<35
So the body of loop executes:
if (sentenceText[i]=='.') statement checks :
if (sentenceText[1]=='.')
This is the second element of sentenceText i.e. e
e is not a period sign so the statement inside if statement does not execute and value of i increments to 1. Now i = 2
So at each iteration the if condition checks if the character at i-th index of string sentenceText is a period.
Now lets see a case where the element at i-th index is a period:
6th iteration:
i=5
i<size is true because i=5 and size = 35 so 5<35
So the body of loop executes:
if (sentenceText[i]=='.') statement checks :
if (sentenceText[5]=='.')
This is the character at 5th index of sentenceText i.e. "."
So the if condition evaluates to true and the statement inside if part executes:
sentenceText[i]='!'; statement becomes:
sentenceText[5]='!'; this means that the character at 5th position of sentenceText string is assigned an exclamation mark.
So from above 6 iterations the result is:
Hello!
This loop continues to execute until all the characters of sentenceText are checked and when the value of i gets greater than or equal to the length of sentenceText then the loop breaks.
The screenshot of the program along with its output is attached.
Maintaining public libraries is a waste of money since computer technology can replace their functions. Do you agree or disagree?
Answer:
I totally do not agree that maintaining public library is a waste of moneyExplanation:
Most library are now advancing in terms of service delivery and public
libraries are no exception as libraries are now incorporating E- platforms/E- libraries, Audio visuals, where anyone can learn or borrow materials electronically.
Furthermore, not everyone can own a computer set to so that public libraries are even relevant to the majorities who can afford a computer set.
Also a library especially the public library is a place where people can meet and socialize to the end we even make friends at the public library more effectively than the online library can make(if they can).
In summary the pros of physical public libraries can not be over emphasized.
Is it appropriate to send an email and call the individual the same day to ask if they have received your email?
Answer:
It depends. (OPINION)
Explanation:
If this is an important email, and it REALLY had to be sent the day of, then yes, it may be appropriate to call the day of. However, if you procrastinated until the last day and are really worried; well; that's your fault. At least wait a day and give the receiver some time to process; they could be really busy.

Explanation:
Initialize the total_owls as 0
Ask the user to enter num_owls_A and num_owls_B, convert the input to int
Sum the num_owls_A and num_owls_B and set it to the total_owls
Print the total_owls

num_zoos = 3
avg_owls = (num_owls_zooA + num_owls_zooB + num_owls_zooC) / num_zoos
print('Average owls per zoo:', int(avg_owls))
There is a problem while you are trying the calculate the average owls per zoo.
As you may know, in order to calculate the average, you need to get the total number of owls in all the zoos, then divide it to the number of zoos. That is why you need to sum num_owls_zooA + num_owls_zooB + num_owls_zooC and divide the result by num_zoos
Be aware that the average is printed as integer value. That is why you need to cast the avg_owls to an int as int(avg_owls)

Explanation:
2 - The function that would find the average of a particular range is =AVERAGE(). This is used to find the average of something by calculating the arithmetic mean (or just "mean").
3 - The function that would find the total values within a particular range---or in this case, Column J---you would use the =SUM() function. This will add up all of the values in the range you selected. An example could be that Column X has the values of 5, 6, 12, 45, 3. =SUM(X1:X5) = 71.
4 - The function that would count all values is defined as =COUNT(). An example would be =COUNT(A1:A10).
5 - The function that would count the number of occurrences within a particular range is defined as =COUNTIF(). Within the parentheses, you would put the range of data that you are working with. Then, in quotations, you would put the name or value that you are trying to find.
