Im in the Variable assignment and Im having no problem putting float radius = 14.5 the problem Im having is setting the printf in task two, I have tried everything and Im coming empty handed.
Is saying to set radius with a printf to output: A ball with a radius of 14.5
Im putting
float radius = 14.5;
printf("%f a ball with a radius"); return 0; I also tried moving things around but no luck have been on this for the past 45 minutes, so a little help would help guys, thanks in advanced.

You can see that the printf begins with the token place holder such as %d %f %c etc then the string statement followed by the variable. Remember when you output a value from a variable in a printf statement you need to put the variable in it to, as the value held in the variable will be substituted for the token place holder.
So to run through an example
int days_in_a_week =7;
//Here you set the return type of a value (int) the name of the variable (days_in_a_week) and then set it equal to 7.
printf("%d days in a week\n", days_in_a_week);
//To output this you put in %d as the place holder as it int value you are returning, then the string you need to output "days in a week", finally followed by the variable which you declared in this case days_in_a_week.
So your output would be printf("A ball with a radius of %f inches",radius);
Hope this helps

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

2,963 PointsIm saddened to say that even though I understand much better with your example, still no luck or results, I have gone to the video about 6 times now, I have even tried on my Xcode a million different ways, I have modified and modified in different versions to see if I can pass this challenge or even get an output on Xcode and nothing has resulted correctly. I cannot get the right output on the challenge or in Xcode. Im not sure what Im doing wrong. And what sad is Im only starting in this course and Im already stuck for hours.
