Why do I see no output?

Question

import java.util.Scanner;
public class Mazrab5 {
public static void main(String[]args) {
Scanner scanner=new Scanner(System.in);

int a=scanner.nextInt();
int b=scanner.nextInt();

for (int i=a++; i<b ; i++) {
if ( i%5==0) {
System.out.println(i);

}
}

scanner.close();
}
}

Answer 1

Hello Dorsa

Your code works.
If you enter 0 and 6 for a and b you will get 0 and 5 as output.
0 % 5 = 0
5 % 5 = 0

Answer 2

Thanks a lot for your attention.

Answer 3

Oh yes! You are right.Thanks a lot.
I just checked it again,but i dont know why it says no output on my computer , but it is correct on my phone

Answer 4

Maybe because of a++
I never tested it but I guess it causes troubles and maybe it creates an undefinded situation (it depends on your compiler what happens).

To increment i you have i++
But you also change i via a++

I would try to print all numbers and see if you overjump numbers.

Btw: I think it is not a good practice to manipulate the start or the end condition while the loop is running.
