Answer:

Question 1:

int numUsers = scnr.nextInt();

Question 2:

public class OutputExample {

public static void main (String [] args) {

int numCars = 99;

Scannerscnr=new Scanner(System.in);

numCars=scnr.nextInt();

System.out.println("There are "+numCars+" cars");

return;

}

}

Question 3:

import java.util.Scanner;

public class Errors {

public static void main(String [] args) {

int userNum = 5;

System.out.println ("Predictions are hard. ");

System.out.print("Especially ");

System.out.print("about the future.");

System.out.println("Num is: "+userNum);

return;

}

}

Explanation:

In Question 1, the statement int numUsers = scnr.nextInt();  reads a new integer value from the keyboard and assigns it to the variable numUsers.

In question 2, Concatenation is used to format the print output.

In question 3, care is taken to fix each of the syntax errors (missing double quotes, semi-colon, concatenation)

What is the name and purpose of the star next to a slide in a PowerPoint presentation?
Finger [1]
If you observe closely, you may see that these stars are shown only against some slides and not all of them.

The stars are just an indication that the particular slide has custom animation. That was you can quickly see at a glance if a slide has content that is animated.

The same star symbol is also shown when the slide itself has any slide transition set.
