Welcome to Treehouse, Dustin Garrett !

Challenge Task 2 of 2 asks you to "Add a printf statement to print the radius variable. Here is what your output should look like: A ball with a radius of 14.5 inches."

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

Saad Ahmed is right - you just forgot to use the radius variable in your printf statement.

Honestly I haven't taken the iOS development code but I think you need to add the name of the float variable.


float numOfHeads = 2.0;

printf("This is an example of %f head being better than one", numOfHeads);

Its worth a try

Thank you!
