Which of the following statements is true? A. Marking a presentation as final is stronger security than password protection. B.

Here's a C code snippet: #include <stdio.h> int main() { int year; printf("enter year:"); scanf("%d",&year); if(year>=2101) { printf("Distant future"); } else if(year>=2001&&year<=2100) { printf("21st century"); } else if(year>=1901&&year<=2000) { printf("20th century"); } else if(year<=1900) { printf("Long ago"); } return 0;} Output: enter year:2018 21st century. </stdio.h>

Here's a C++ code snippet: #include <bits/stdc++.h> using namespace std; int main() { int n=50; int arr[n]; cout << "Enter 50 integers: "; for (int i = 0; i < n; i++) cin >> arr[i]; cout << endl; sort(arr,arr+n); for (int i = 0; i < n; i++) { cout << "pair which gives sum equal to " << arr[i] << " is:"; for (int j = 0; j < n; j++) for (int k = j + 1; k < n; k++) if (arr[i] == arr[j] + arr[k]) cout << "(" << arr[j] << " & " << arr[k] << ")" << ","; cout << endl; cout << "*******************************" << endl; } return 0; } The program will gather 50 integers from the user, sort them in ascending order, and identify all pairs that total to any of the array's elements, followed by printing those pairs.

Answer: Scanners used in supermarkets for barcodes and voice-activated phone menus are not examples of artificial intelligence.

Explanation:

(a) Supermarket barcode scanners can read codes, yet they lack the capability to employ machine learning techniques for learning patterns within the codes. Machine learning is a crucial aspect of artificial intelligence (AI), thus indicating they do not qualify as instances of AI. Likewise, voice-activated menus can only present options and do not carry out any complex tasks.

In contrast, web search engines and internet routing algorithms demonstrate dynamic and intelligent capabilities in processing and delivering information to users.

Hence, these are considered examples of AI.

The code relevant to the problem in question:

import java.util.Scanner;

public class Test {

   public static void main(String[] args) {

       double number;

       double squareRootOfNumber;

       String userInput = null;

       Scanner scanner = new Scanner(System.in);

       System.out.println("Please enter a number: ");

       userInput = scanner.next();

       number = Double.parseDouble(userInput);

       squareRootOfNumber = Math.sqrt(number);

       if (number < 0) {

           throw new ArithmeticException("Cannot compute the square root of a negative number");

       }

       System.out.format("The square root of the entered number is %.2f %n", squareRootOfNumber);

   }

}

The program will output:

Please enter a number:

-90

Exception in thread "main" java.lang.ArithmeticException: Cannot compute the square root of a negative number at com..ans.Test.main(Test.java:18)

Explanation:

The standard Java library function java.lang.Math.sqrt does not throw an ArithmeticException for negative arguments, hence there’s no need to enclose your code in a try/catch block.

Instead, we manually trigger ArithmeticException using the throw keyword:

throw new ArithmeticException("Cannot compute the square root of a negative number");
