Have a midterm tomorrow. Need help badly.

I have to know WHY these functions give the  answers they do.  I'm at a loss when it comes to figuring out what order a program will run shit.

If anyone can give any insight, thanks.

(10%) What is printed in the "alert" box at the end of running this JavaScript code fragment?

   var i;            // loop index
   var flag = true;

   for (i=0; i<5; i++) {
      flag = !flag ;
   }

   alert(flag);

Next one:

(10%) What is printed in the "alert" box at the end of running this JavaScript code fragment?

   var x = 5;         
   var f = 5;

   if (x < 10 ) { x = x + 1; }
   else if (x == 5) { x = x - 2 ; }
   else if (x > 0) { x = x * 3; }
   else { x = -8 ; }

   if (f < 10 ) { f = f + 1; }
   if (f == 5) { f = f - 2 ; }
   if (f > 0) { f = f * 3; }
   else { f = -8 ; }

   alert("x: " + x + ", f: " + f);

Two more to come.
