its giving me an error at compile saying:

Code:

---

main.c: In function 'main':
main.c:16: error: expected ';' before ')' token
main.c:16: error: expected expression before ')' token

whats going on?

First, you need to declare 'i' at the start of main, so

int main() {

int i;

next, in your for loop, there should be ';' instead of commas.

for(i = 5, i > 0, i--) ---> for(i = 5; i > 0; i--)

Give that a go.
