C for loop quiz: Am I missing something?

Ok, the quiz asks: Let's create a for loop which will loop 5 times and print the value of "i". Fill in the blanks below.

So I submit the following code.

for (int i = 0; i < 5; i++) { printf("%d\n", i); }

The quiz answer says this is incorrect. However when I run it in Xcode, sure enough the thing loops five times and spits out the value of i.

I know this is totally a noob question, but what am I missing here? Why is the quiz telling me I'm wrong?

Not sure if it is relevant, but I have had issues with declaring variables inside for loops in C before.

Maybe try

int i;
for (i = 0; i < 5; i++) {
  printf("%d\n", i);
}

Good. Just so I'm not crazy and this is on Treehouse, not me.
