Functions Code Challenge

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)

" float addTwo (float x, float y);

float x = 5.55; float y = 0.11;

float addTwo (float x, float y) { return x + y; } "

you are doing more than what is asked for. all you are required to do is write the function, nothing more. 

float addTwo (float x, float y) { return x + y; }

is correct, however you dont have to define the prototype or any other variables. all you need is the function definition which is your last line

It still says that it is incorrect. Is there a bug?

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

For me it's right... Maybe you missed the semi colon? I did that initially.
