iOS Objective-C Basics (Retired) Functional Programming in C Functions

Can't pass the challenge

I am in the functions' challenge which is asking to: Implement a function named "addTwo" that returns the sum of two floats. The function will accept two float numbers as arguments and return a float which is the sum of the two arguments passed to the function. (No need to write the main function just write out the implmentation for the addTwo function)

I have tried every single variation of the answer and can't get past it,

My answer is:

float addTwo(float a, float b) { return a+b; }

it's not accepting it... any clue?

Your answer is right. Some recent changes to challenge broke it. Sorry about the inconvenience but it should work now.

your code looks good. ive seen about 10 posts about this today and tried the challenge myself and couldnt get it to work either. It looks like there might be a problem with the challenge itself, not your code. I would just skip it and come back to it later.
