Hey everyone, I am very new to coding, and I will need to be helped out quite a bit at the beginning. I am very excited about it though, and look forward to learning lots more about it, and I have a dream of one day making my own website and iPhone app :) I am currently stuck though on the challenge task for the iOS Development track, under the Fundamentals of C course in the variables lesson for challenge task 1. I have tried the code probably 50 times in different ways, but even on the preview it pulls up a blank and I am at a loss. The challenge is to create a "float variable for 'radius' is equal to '14.5'. Here is my code that i have continued to tinker with.
include <stdio.h>
int main() { float 'radius' = 14.5;
printf("%f radius.\n", radius);
return 0;
}

glad you're excited about coding, but it looks like you gave the compiler a little more than what it was asking.
so if we break the question down. Create a float variable named 'radius' with the value '14.5'.
simply, only do just that.
your first line is correct. with the exception of the single quotes.. everything else following can wait && it may be used in part two of the code challenge.

516 PointsWow! Thanks so much! That was exactly it!! Thanks for the help!! It just went through. I guess I got a little excited and did the whole C formula haha

16,433 Pointslmao, its cool man. btw, probably the most difficult thing in programming to me is understanding what the question is asking, after you figure out what it's asking, implementing the code should be a breeze.

516 PointsThat's good advice, not to pester you more, but how then do I make a printf statement? I am adding the text in the quotations after the %f but it is saying not to make a NSSAstring but a normal printf string? You get it? haha

16,433 Pointsyou're not bothering me, i actually wish people would really ask more questions in the forums i don't think they ask enough.
However, you already have the syntax(meaning arrangement, but programmers use the word syntax instead) correct in your answer above. but i believe the question wants you to use that float value you created in a sentence.
i know exactly where you're struggling. look at it like this.. The sentence in the instructions reads "A ball with a radius of 14.5 inches."
well, the question wants you to use that float value you created. They want you to use the value you created to complete the rest of this sentence. So until you 'substitute' it in the sentence, the sentence basically reads like this "A ball with a radius of ___ inches."
with that being said, when you use the printf statement with that sentence that the instructions gave you, you have to think.. how can i fill in this blank with the float value i just created? Then you're like, oh yeah i use %f to substitute for the blank.
so now that you filled in the blank your printf statement should read "A ball with a radius of %f inches." because you filled in the blank.
I answered your question but didn't give you the full answer, let me know if you get it.

Thats my code:
int main() { float radius = 14.5; }
Can you help me out?

Rashii Henry
16,433 Pointshmm, that's weird. I was going to say that within the code challenge there's no need to insert the main argument. just declare and assign the value to the float. but good job man.
