Why does while() sometimes go one step above?

I keep coming across tasks where while goes above the value it is supposed to. For an example: int i = 9, x = 2; while(i-->3) { ++x; if(x<=4) continue; else if(x<=6) x+=3; else break; } In this case while will break after 4 loops, x will first be 3, then 4, then 5 and then 6+3=9. Why does it get to 5 when it's set to stop continuing after 4? Can someone please explain this?

Continue does not mean stop continuing. It means that everything after continue will not be executed and the control returns to the beginning of the loop.

continue statement causes to skip instructions next to that and proceeds with next iteration. In that code, if condition fails when 5<=4, and else if part get executed, in next iteration breaks the loop.. Continue means only skip correct iteration right now, and continue with next iteration..
