error

Question

import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int amount = scanner.nextInt();
//your code goes here
for (int i=0;i<6;i++){
int remainder=amount*9/10;
}System.out.println(remainder);
}
}
You take a loan from a friend and need to calculate how much you will owe him after 3 months.
You are going to pay him back 10% of the remaining loan amount each month.
Create a program that takes the loan amount as input, calculates and outputs the remaining amount after 6 months.
Sample Input:
20000
Sample Output:
10628
hi guys
i wrote a program for above question
but i saw error on running this program.
what's my wrong?

Answer 1

Variable int <remainder> is defined within the for...loop. It is only recognised inside the loop.
You can instead, work with <amount> directly. Try to put this in the loop
amount -= ( amount * 0.1 );
