while statement help

I know that -- descrease the number and ++ increases the number. Does it just decrease by 1 or is it based on something else?

int x=2
int y=10

while (x<y)
{if ((i%2)==0)
x++:
else 
y--;
}
cout<<x<<endl;

So if I understand that correctly, y should be 3 and the output should also be 3

i think you want.

(x % 2)  

instead of

(i % 2)

you are correct -- decrease by 1 and ++ increase by 1.
