c. Input control.
Explanation:
- Such a type of control in which keep updating data on the basis of monitoring of data is known as Processing Control. Data matching is an example of processing control.
- Data Transmission Control is such a control in which transmission of data is done. Parity check is an example of data transmission control.
- Input Control is such type of control in which user can perform different tasks like adding text. Sequentially pre-numberered forms and turn around documents are an example of an input control.
- Examples of Data entry control include batch total and validity check.
Answer:
In Java:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String isbn;
System.out.print("First 1:2 digits: ");
isbn = input.nextLine();
if(isbn.length()==12){
int chksum = 0;
for(int i = 0; i<12;i++){
if((i+1)%2==0){ chksum+= 3 * Character.getNumericValue(isbn.charAt(i)); }
else{ chksum+=Character.getNumericValue(isbn.charAt(i)); } }
chksum%=10;
chksum=10-chksum;
if(chksum==10){
System.out.print("The ISBN-13 number is "+isbn+"0");}
else{
System.out.print("The ISBN-13 number is "+isbn+""+chksum); } }
else{
System.out.print("Invalid Input");
} }}

Health care robots the key word, being "robots" aren't able to act as we can as humans.
Robots and systems lack the emotional skills that we as humans have, they are not intuitive.
There are many risks in using robots for health care, although, "health care" is a vague term, so I'll cover a few in general:
- Doctor/patient confidentiality is risked when using robots to handle personal medical matters, systems are never 100% secure.
- Robots and systems cannot emphasise with patients and will make decisions based on logic and theoretics, not emotionally - for example, if a patient is in a state of bad mental health, a robot will not be able to effectively analyse the right methods to take.
- The collection, storage and passing-on of patient information is risked as system encryption is never guaranteed.
