variables

Any help please!? Link : http://teamtreehouse.com/library/variables-2

I started out with this: float radius = 14.5; printf("A ball with a radius of %f inches\n", radius);

And this is what the system keeps saying:

Bummer! Make sure you are passing a string instead of a NSString to printf. Also, make sure you have the correct format options. (%f is used for floats)

I copy pasted your answer and just got 12 points on the go, thats when I haven't started with Objective -C yet. Works fine for me without any error :)

for first float radius = 14.5;

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

= +12 points

Your answer looks right to me, although it should be in two separate lines. One you have used the semi-colon you can't have any other statements after it on the same line...

eg:

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

actually I believe you can have as many statement on one line as you want, just as long as your syntax is correct and you end each statement with a semi colon. The compiler doesnt take into account white space and line breaks.

here is the code editor is expecting: float radius=14.5; printf("A ball with a radius of %f inches",radius);

you actually addedd \n in the end of the quotes which the editor is not expecting and thats why a bummer happened. You need to do exactly what the question is asking and nothing less or nothing more and then only it will let you pass.
