Functions code challenge

This is the full code for the solution and it is working for me. Take a look at it when you have the time.

float addTwo(float a, float b); 

int main() {
    float a = 2; 
    float b = 3;

    printf("add Two %f\n", addTwo(a, b)); 

    return 0;   
} 

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

I was having the same problem as you. What isn't made very clear in this problem (to a beginner) is that you don't have to declare the addTwo function and then main(), since that is technically already set up when you open a C program (but not really). I believe that is inferred when you are doing a challenge. What the question asks for is to just implement the function itself (which again, wasn't super clear to me). The challenge accepted this answer.

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

Your answer is almost right. Firstly, the challenge is asking you accept and return a float. So wherever you have an int you should replace that with a float. Next, all you need is the implementation of the function, which means just the last 4 lines from what you pasted above.

Make sure that your arguments and return type for the function addTwo are correct. You are using int, but they should all be floats. Also, in your format string you should use %f (floats) and not %d (integers).

Thank you both for your help. I changed the code to:float addTwo(float a, float b); float main() {

float a = 36; float b = 37;

printf("add Two %f\n", addTwo(a, b)); return 0; } float addTwo(float a, float b); { return a + b; }

Now its giving me this answer: Bummer! Make sure you've defined the return type and both paramter types as 'float' and that you are returning the result.

I honestly don't know what else I'm missing i did try changing the first return to a + b. Just to see if that would make a difference which it didn't. Went back to the answer above yet, still no dice.

Look closely:

float addTwo(float a, float b); { 

There should not be a semicolon before the curly bracket. Remove it, and you're fine.

Thank guys, Eirik Vale AAse I tried what you said and it still isn't working. Maybe i've been fighting this too long. I'll take a break then watch the video and try again. Once again thank you :)

Thanks for all your help guys, and it's okay that it's challenging that's what keep it interesting. :D

:D yes it did I passed it already but thank you .

Like some people here I did declare everything. Actually my code was right but not accepted. I tried and tried again and then finally found the solution here :) I think the description is clear but I thought I had to do the whole stuff just like in the videos :P

I am trying to figure out where in the video training it relates these? I am just confused on how you came to this conclusion to start with. I am assuming as a new beginner/newbie that it is looking for just the last line of code? For example from the video

int funky_math(int a, int b) { return a + b + 343;

change all the int to floats?

I think the main issue with this code challenge is that it is asking you to use floats. Floats are not mentioned until the next video after this particular code challenge.

I was having the same problem as Spencer Sheehan. I think the question needs to be reworded so it's easier for beginners to understand.
