I am stuck on Question 2 of the Variables Section in the C Basics section. Floating variable

Am I doing this wrong? Trying to get the phrase "A ball has a radius of 2.45 inches".

float radius=2.45

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

Hey there,

I just started iOS dev with Objective C too!

When I was on that task this is what worked for me:

float radius = 2.45;

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

Where you declare the variable again after the printf "" statement.

Hope this helps!
