%f

I believe I've answered the question correctly. However, it seems my %f is not recognized as proper formatting for float. Is there an error in my code, or is there something else happening here?

variable_assignment.mm 
float radius = 14.5;

printf("A ball with a radius of %f inches.\n" radius);

Probably it does not compile because you missed a comma separator in the printf function. It should look something like this:

float radius = 14.5;

printf("A ball with a radius of %f inches.\n", radius);
