Am i right on Fibonacci sequence?

Question

package fib;
import java.util.*;
public class fib{
public static void main(String[]args){
Scanner vip = new Scanner(System.in);
int t1 =0;
int t2= 1;
System.out.println("enter number of time to be carried out");
int n = vip.nextInt();
System.out.println("your fibonaccis sequence is");
System.out.print("first " + n + " terms: ");
for (int i=1; i <= n; ++i)
{ System.out.print(t1 + " + ");
int sum = t1 + t2;
t1 = t2;
t2 = sum;

}
}
}

Answer 1

yes, surely pre-increment and post-increment makes a huje difference

Answer 2

yes it has an effect as u initized a variable i with 1 if you use ++i then it will first incrememt to 2 before proceding, if you use i++ then it will increment to 2 after loop execution for first time

Answer 3

yes but there is 1 logical error...
you must use post-increment i.e use "i++" instead of "++".

Answer 4

ok...but does that have effect on the program
