What happens when a circulatory system and computing system are connected by abstraction?
When a circulatory system and computing system are connected by abstraction, it allows for the exchange of information and data between the two systems. This enables the circulatory system to control the computing system and receive feedback from it, allowing for the development of more complex systems. By abstracting the two systems, it allows for the development of powerful medical applications that can monitor and adjust the circulatory system in real time. For example, this could be used to adjust a patient's blood pressure or monitor their heart rate in order to prevent dangerous conditions from developing.

C++ - Did I write this code correctly? I am unable to output the conversion I created, so I am not sure if I am missing something. Here are the instructions:
Prompt
In this assignment, you are presented with a text document that includes six cities and their average yearly temperature in Fahrenheit. Your goal is to read that data, convert it to Celsius using the provided formula, and then write that new data to its own file.
To begin your work, open Visual Studio and create a new C++ project. Save the provided FahrenheitTemperature.txt document in a location where you will easily be able to access it while you work in Visual Studio. For this assignment, you will be submitting only your C++ (.cpp) file. You do not need to submit the final converted data; the C++ code you create just needs to be able to generate that file.
Specifically, you must address the following rubric criteria:
Develop code to read data from a text file. Your work should be completed using C++. Read the provided document, FahrenheitTemperature.txt, which includes data on the average yearly temperature for six different cities in degrees Fahrenheit. Note that a space separates each city from its temperature. Assume the city’s name does not include any spaces or special characters (the name should consist of only a single word). Also assume the provided temperature is presented as an integer. Consider the following steps as you work:
Open the provided file so it is ready to be read. Remember the file is named FahrenheitTemperature.txt. Watch out for the class you use, and make sure it is for reading a file and not writing to a file.
Read data from the provided file. Remember, to read this file you will need to declare a variable. Begin by reading the first value and putting it in the first variable. Then read the next value and put it in the second variable.
Once this is complete, be sure to close the file. This releases the file so it can be used again.
Develop code to write data to a text file. Your work should be completed using C++. Title the new document you are creating CelsiusTemperature.txt. The name of the output file needs to be different from the name of the input file so you do not overwrite and erase the input file. Consider the following steps as you work:
Declare a variable to point to the file that will be written to. Watch out for the class you use, and make sure it is for writing to a file and not reading a file.
Create the code instructions for writing data to the new output file. In this new file, include space for both the name of the city and the temperature in Celsius for each city included in the original input file. You will need to complete the Fahrenheit-to-Celsius conversion calculation before you write to the new file. Use the following formula to make this conversion. Note that °F represents the temperature in degrees Fahrenheit while °C represents the temperature in degrees Celsius.
Close the file once you are done writing to it. If you attempt to look at the results in the file before completing this step, your file may appear empty.

outFS << cityName << " " << tempCelsius << endl;
}
//Closing files
inFS.close();
outFS.close();
return 0;
}
Answer:
This code looks correct, but there is a small issue that may affect the accuracy of the temperature conversion. In the calculation for the temperature in Celsius, you are dividing 5 by 9 using integer division, which means that the division will be truncated to an integer and any decimal values will be discarded. To avoid this, you need to cast one or both of the values to a floating-point type, such as double.
Explanation:
#include <iostream>

C/C++ does not allow arrays to be manipulated as a whole; each element must be set or accessed individually. To make operating on whole arrays or contiguous portions of arrays easier, write the following utility functions.
void arrayFill(int *p,int n,int v); // fill n elements starting a p with the value v
void arrayReverse(int *p,int n); // reverse the order of n elements starting a p
void arrayCopy(int *p,int n,int *q); // copy n consecutive elements from q to p
bool arrayEqual(int *p,int n,int *q); // iff n consecutive elements of p and q are equal
You will need to write your own test code to make sure your functions work correctly. The follow is an example of how to do this, but it is unlikely to find all errors.
#include
int main()
{
int a[20] = {1,2,3,4,5,6,7};
arrayReverse(a+2,3);
assert(a[2] == 5);
assert(a[4] == 3);
arrayCopy(a+7,6,a+1);
assert(a[12]==7);
arrayFill(a+13,6,-1);
int b[20] = {1,2,5,4,3,6,7,2,5,4,3,6,7,-1,-1,-1,-1,-1,-1};
assert(arrayEqual(a,20,b));
}
NOTE: Your submission may not use the array index operator ([]). You must use pointers.
Submit your functions without main().
Answer:
#include <assert.h>
void arrayFill(int *p, int n, int v)
{
for (int i = 0; i < n; i++)
{
*p = v;
p++;
}
}
void arrayReverse(int *p, int n)
{
int *q = p + n - 1;
while (p < q)
{
int temp = *p;
*p = *q;
*q = temp;
p++;
q--;
}
}
void arrayCopy(int *p, int n, int *q)
{
for (int i = 0; i < n; i++)
{
*p = *q;
p++;
q++;
}
}
bool arrayEqual(int *p, int n, int *q)
{
for (int i = 0; i < n; i++)
{
if (*p != *q)
{
return false;
}
p++;
q++;
}
return true;
}
Explanation:
The code includes 4 utility functions to make operating on arrays in C++ easier:
arrayFill: This function takes a pointer to an integer (p), the number of elements to be filled (n), and a value to fill the elements with (v). It uses a for loop to iterate through the n elements, starting from the pointer p, and sets each element to the value v.arrayReverse: This function takes a pointer to an integer (p) and the number of elements to be reversed (n). It initializes a pointer q to point to the last element of the array (p + n - 1). Then it uses a while loop to iterate through the elements, starting from the first (p) and last (q) elements, swapping the values of each pair of elements until the pointers meet in the middle.arrayCopy: This function takes two pointers to integers (p and q) and the number of elements to be copied (n). It uses a for loop to iterate through the n elements, starting from the pointer q, and copies each element to the corresponding location pointed to by p.arrayEqual: This function takes two pointers to integers (p and q) and the number of elements to be compared (n). It uses a for loop to iterate through the n elements, starting from the pointers p and q, and compares each pair of elements. If any pair of elements are not equal, the function returns false. If all pairs of elements are equal, the function returns true.You have been working with an ISP (Internet service provider) as a network engineer.

Answer: This is not real. the person is using bots to answer questions speedily.
Explanation:
Suppose Tserial = n and Tparallel = n/p + log2(p), where times Tserial and Tparallel are in microseconds. Assume p represents the number of processes.
a) Write the expressions for speed up and efficiency.
b) Find the speedup and efficiency for n = 10000 and p = 16.
The speed up is 15.86 and the efficiency is 0.994.
How to calculate the speedThe speed up (S) is defined as the ratio of the time taken to execute a task serially to the time taken to execute the same task in parallel. It can be expressed as:
S = Tserial / Tparallel
The efficiency (E) is defined as the ratio of the actual speed up achieved to the maximum possible speed up. It can be expressed as:
E = S / p
b) To find the speed up and efficiency for n = 10000 and p = 16, we substitute these values into the expressions for Tserial and Tparallel:
Tserial = 10000
Tparallel = 10000 / 16 + log2(16) = 625 + 4 = 629
S = Tserial / Tparallel = 10000 / 629 = 15.86
E = S / p = 15.86 / 16 = 0.994
So the speed up is 15.86 and the efficiency is 0.994.

Explanation:
Categorical variables are present in nearly every dataset, but they are especially prominent in survey data. In this chapter, you will learn how to create and customize categorical plots such as box plots, bar plots, count plots, and point plots. Along the way, you will explore survey data from young people about their interests, students about their study habits, and adult men about their feelings about masculinity. This is the Summary of lecture "Introduction to Data Visualization with Seaborn", via datacamp.
Categorical plots are useful for visualizing survey data, such as box plots, bar plots, count plots, and point plots. This chapter will teach how to create and customize these plots, to better understand survey responses from young people, students, and adult men.
Categorical plots are an important tool for visualizing survey data. They allow us to compare responses across different categories, helping to uncover patterns and trends in the data. You will learn how to design and modify categorical plots, including box plots, bar plots, count plots, and point plots, in this chapter. You will also look at survey information on students' study habits, males in their 20s and 30s, and young people's attitudes towards masculinity. Each plot type offers benefits that help you analyse the data and discover insights. Bar plots are useful for showing the relative frequency of replies, whereas box plots can be used to compare the distributions of responses for various categories. The responses from various categories can be compared using count graphs and point plots.

Creating a Shell Script
You will use command line arguments for the x and y values.
Be sure you follow the directions exactly.
Create a shell script named arithmetic_2.sh using Nano (or the GUI text editor if you prefer).
The script needs to perform the following pseudo code in the order shown:
Check to see if the user entered two numbers on the command line following the script name. If not, display an error message and exit, otherwise continue on.
Assign the first argument to a variable named x.
Assign the second argument to a variable named y.
Display the two values.
Divide y by x and display the result.
Save the file, and test it in the terminal. (What must you do before you can run it?)
When you’re satisfied that it works, upload it to Canvas.
If the user fails to supply the two values as arguments on the command line, prompt the user to enter them like you did in the first arithmetic exercise.
Do the above, but if the user gives you only one value as a command line argument, use it for the first one (x), and ask for the second one.
NOTE: Some of you may already know that doing simple division in a shell script usually results in whole number (integer) results. That's OK for the purpose of the exercise, which is to use command line arguments. Dividing by zero is something we wish to prevent, so check the input for x.
arithmetic_2.sh reads two command line arguments for x and y, displays them, checks x is not 0, and displays the result of y/x, while prompting for input if arguments aren't given or only one argument is given.
To create a shell script named arithmetic_2.sh that performs the above operations using command line arguments for the x and y values, the script needs to follow the following pseudo code in the order shown:
Check if the user entered two numbers on the command line following the script name. If not, provide a warning and stop; else, go ahead.Put the first argument into the x variable.Put the second input into the y variable.Display the two values.Check if x is equal to 0. If it is, display an error message and exit, otherwise continue on.Calculate y/x and display the answer.Prompt the user to provide the two values as in the first arithmetic exercise if the user forgets to supply them as arguments on the command line. If the user only gives you one value as a command line argument, use it for the first one (x) and ask for the second one.
Before running the script, make sure to make it executable by running the command chmod +x arithmetic_2.sh in the terminal.

The header file string contains the function ____________________,which converts a value of type string to a null-terminated character array.
the destination string is not large enough to hold the source string, then it can cause a buffer overflow.
strcpy() is a function declared in the header file string.h. It is used to copy a source string to a destination string. It takes two arguments, the first being a pointer to the destination string, and the second being a pointer to the source string. It then copies the characters from the source string to the destination string until a null-terminator is reached, at which point it returns a pointer to the destination string. The important thing to note is that the source string must be a null-terminated character array. It is important to note that this function does not check for buffer overflows, so if the destination string is not large enough to hold the source string, then it can cause a buffer overflow.
