Code aprox. of pi does not run :(
I had to write a code that approximated pi. The code compiles, but nothing happens when I run it. What should I change.

Remove the semicolon from line 13,
while (totalcount < 1000000);
At lines 33 and 34 there is integer division, which won't give the result you are expecting.
