Thread: Convert for loop to while loop

Hi, could someone help me convert this for loop to while loop
And how to detect how many times each one is executed or evaluated please?
Thank you

Code:

int x=1, a=33;
for(a=17; a< 20; a++){
	x++;
}

int x=1, a=33;

while(          ){

	x++;

}

Final value of a:______ 
Final value of x:______ 
How many times a=17 is executed :______
How many times a< 20 is evaluated:_______
How many times x++   is executed:________
How many times a++ is executed:_________
