assuming code:


int i=0;//global variable


//process 1        //process 2
int num=0;          int num=0;
while(i<5){         while(i<5){
  num=num+1;        num=num+1;
  i=i+1;            i=i+1;



}                    }


what is the range of values for num?
it is supposed to be from 0-15, but i dont know why- any thoughts?
