To assess the treatment options and costs for osteoarthritis of the knee (OAK), a condition that affects the knee joint and progresses over time owing to cartilage and bone deterioration.

Methods: Over the course of two years, we prospectively examined the clinical results and quantified cumulative direct expenses of patients with OAK sent to our multidisciplinary OA programme.

A total of 133 patients were evaluated. All showed radiographic signs consistent with moderate to severe OAK. We tracked and examined changes in the Western Ontario McMaster Osteoarthritis Index (WOMAC), Minimal Clinically Important Improvement (MCII), and BMI.

The total direct expenditures for all subjects' medical and surgical care during a two-year period were calculated.

Write a program that will open the file random.txt and calculate and display the following: A. The number of numbers in the file
Rama09 [41]

Answer:

Here is the C++ program:

#include <iostream>  //to use input output functions

#include <fstream>  //to manipulate files

using namespace std;  //to identify objects like cin cout

int main(){  //start of main function

  ifstream file;   //creates an object of ifstream

   file.open("random.txt"); //open method to open random.txt file using object file of ifstream

       

    int numCount = 0;  //to store the number of all numbers in the file          

    double sum = 0;   //to store the sum of all numbers in the file

    double average = 0.0;   //to store the average of all numbers in the file

    int number ; //stores numbers in a file

                 

        if(!file){   //if file could not be opened

           cout<<"Error opening file!\n";    }   //displays this error message

       

       while(file>>number){   //reads each number from the file till the end of the file and stores into number variable

           numCount++; //adds 1 to the count of numCount each time a number is read from the file          

           sum += number;  }  //adds all the numbers and stores the result in sum variable

           average = sum/numCount;  //divides the computed sum of all numbers by the number of numbers in the file

     

       cout<<"The number of numbers in the file: "<<numCount<<endl;  //displays the number of numbers

       cout<<"The sum of all the numbers in the file: "<<sum<<endl;  //displays the sum of all numbers

       cout<<"The average of all the numbers in the file: "<< average<<endl;  //displays the average of all numbers

       file.close();     }  //closes the file    

   

Explanation:

Since the random.txt is not given to check the working of the above program, random.txt is created and some numbers are added to it:

35

48

21

56

74

93

88

109

150

16

while(file>>number) statement reads each number and stores it into number variable.

At first iteration:

35 is read and stored to number

numCount++;  becomes

numCount = numCount + 1

numCount = 1      

sum += number; this becomes:

sum = sum + number

sum = 0 + 35

sum = 35

At second iteration:

48 is read and stored to number

numCount++;  becomes

numCount = 1+ 1

numCount = 2    

sum += number; this becomes:

sum = sum + number

sum = 35 + 48

sum = 83

So at each iteration a number is read from file, the numCount increments to 1 at each iteration and the number is added to the sum.

At last iteration:

16 is read and stored to number

numCount++;  becomes

numCount = 9 + 1

numCount = 10    

sum += number; this becomes:

sum = sum + number

sum = 674 + 16

sum = 690

Now the loop breaks and the program moves to the statement:

       average = sum/numCount;  this becomes:

       average = 690/10;

       average = 69

So the entire output of the program is:

The number of numbers in the file: 10                                                                                                           The sum of all the numbers in the file: 690                                                                                                     The average of all the numbers in the file: 69

The screenshot of the program and its output is attached.

Cloud [144]

Arturo is attempting to protect the database (data) of an information system (IS).

<h3>What is an information system?</h3>

An information system (IS) can be defined as a set of computer systems, that is typically used to collect, store, and process data, as well as the dissemination of information, knowledge, and the distribution of digital products.

In Cybersecurity, there are two (2) main techniques that can be used to check data when inputted in an information system (IS) and these include:

  • Verification
  • Validation

Data validation is a type of check which is primarily performed by a software program (application) to make sure that the data which is entered into an information system (IS) is allowable and sensible.

This ultimately implies that, any data that is not allowed or sensible are rejected and discarded by the computer system.

In conclusion, we can deduce that Arturo is attempting to protect the database (data) of an information system (IS).

Angela should make sure the hamburger patty is disposed of and a new one prepared for the hamburger. She should reprimand Patty as what she did is wrong. Patty could well be fired for what she did. It is unsafe and unsanitary to give a customer food that has fallen on the floor. Angela should make sure this never happens again.
