can anybody guys tell me why we are using amount=remaining in 13th line? and why we are using print statement in the outside ?

Question

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int amount = scanner.nextInt();
int remaining=amount;
//your code goes here
for(int i=0;i<3;i++){
int payment=((amount)/10);
remaining=amount-payment;
amount=remaining;
}
System.out.println(remaining);
}
}

Answer 1

MATHIVANAN T A
The variable - amount is being re-assigned the value of remaining each iteration of the loop.

The print statement is outside the loop so you only get a visual result once the loop has finished.

Answer 2

You can eliminate the use of remaining variable. Directly use amount, instead.

amount = amount - payment; //even replace payment with by amount/10.
