Increment and decrement

Question

Tom and Bob are playing a board game, in which both players start with the same number of points. Tom won the first game and got 1 point, while Bob lost the game, and therefore lost 1 point.

You are given a program that is intended to take the initial score and increase Tom's score by 1 and decrease Bob's score by 1.
But something is wrong: the program outputs the scores without the change.

Task
Fix the program to result in the expected outputs.

Sample Input
5

Sample Output
Round 1 results:
6
4

Explanation
Both players had 5 points at the start of the game. After the first game, Tom gained 1 point (6, the first outputted number), and Bob lost 1 point (4, the second outputted number).

Answer 1

</CODER> completely missed the part about increments and decrements. (and adding a point to the team of locked cases)
Shreyas Vaidya, what is the difference between pre-increment and post-increment. Your answer is almost correct and I believe that if you answer my question, you'll see the solution to your code error.

Answer 2

Before expecting answer from community, please provide yours attempts.
The exersize is about to learn and use pre - increment/ decrement operators use. And know difference between pre and post increment/ decrement

Here it uses post increment/ decrement which output same value, even though it updates scoreTom value. Instead if you use pre increment/ decrement thenga fixes the fault. So instead,
//fix
System.out.println(scoreTom++);
System.out.println(scoreBob--);

It expecting to use :

System.out.println( ++scoreTom );
System.out.println( --scoreBob );

Hope it helps.

Answer 3

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);
//taking initial score
int initScore = scanner.nextInt();
int scoreTom = initScore;
int scoreBob = initScore;

System.out.println("Round 1 results:");
//fix
System.out.println(scoreTom++);
System.out.println(scoreBob--);
}
}

Can you please tell me the answer
