Hi there, just wondering why Xcode tells me this is okay, but it being rejected as incorrect?

// // main.c // MyFirstCProgram // // Created by turner on 9/26/13. // Copyright (c) 2013 treehouse. All rights reserved. //

include <stdio.h>

int main() {

int days_in_a_week = 7;
float cm_to_in = 2.54;
float radius = 14.5;
char the_w;
the_w = 'W';

// insert code here...
printf("%d days in a week.\n", days_in_a_week);
printf("%f cm per in.\n", cm_to_in);
printf ("%f radius\n", radius);
printf("The %c is a cool hotel\n", the_w);
return 0;

}

Thank you Steve!

I think the challenge is looking for:

float radius = 14.5;
printf("A ball with a radius of %f inches", radius);

I can't see where all the other variables have come from, unless I'm reading a different code challenge.

Steve.
