Can someone explain to me why 8 is the correct answer in this code below

Question

public class Program
{
public static void main(String[] args)
{
int x=2;
for(int i=1; i<=3; i++)
{
x+=i;
}
System.out.print(x);
}
}

//Output: 8

Answer 1

So first x has the value of 2 and then the loop begins.

x += i evaluates to x = 2 + 1 which is 3.
For the second run of the loop x += i now evaluates to x = 3 + 2 which is 5.
For the third run of the loop x += i evaluates to x = 5 + 3 which is 8.
Then once i is 4, i <= 3 is then false so the loop is exited and the value is x (8) is printed.
