Question

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
double amount = scanner.nextInt();
//your code goes here
for(i=0;i<3;++i) {
amount = (0.9) * amount;
}
System.out.println(amount);
}
}

Answer 1

1. Use of .nextInt() method (which reads an `int`) for value assignment of a `double` variable <amount>. Use .nextDouble().

2. Unspecified data type for variable <i> in the for...loop construct. Define data type for variable <i>.
