Courses Plus Student 1,302 PointsCan't past the Functional C Programming challenge
I simply don't know how to complete it. Don't see any relation with the class.
Basilio Guzmán
Courses Plus Student 1,302 PointsYes, I just have the challenge left, the one with the functions and I don't understand the challenge.

Courses Plus Student 94,610 PointsIf you go back 2 videos to this one: http://teamtreehouse.com/library/objectivec-basics/functional-programming-in-c/functions
And review it starting from 1:44 it shows you almost exactly what you need to do for this challenge. It may be good for you to review this part if you don't have any idea where to begin on this.
Keep in mind that the challenge does not want a complete program with a function declaration, the main function, and then a function definition at the bottom. It only wants the function definition or the implementation of the function.
Basilio Guzmán
Courses Plus Student 1,302 PointsStill don't understand what to do. In the video explain one thing, that explanation doesn't work for me in the challenge.
Jason Anello
Courses Plus Student 94,610 PointsOk, so if you look at the 3:00 mark in that function video you will see at the bottom that the instructor wrote the implementation of the funky_math function.
int funky_math(int a, int b) {
return a + b + 343;
}
That's the definition or the implementation of the function. This function has 2 parameters that are int's and it also returns an int. The return value is the sum of the 2 arguments passed in plus 343.
The challenge wants you to do something very similar to this but you need to change each part to what the challenge is requesting. You want to change the data types, the function name, and the return value.
Post what code you have if you're still having trouble.
Basilio Guzmán
Courses Plus Student 1,302 PointsI'm trying the following:
float addTwo (float a, float b) { return a + b; }
not working
int addTwo (float a, float b) { return a + b; }
not working
float addTwo (float a, float b) { return float a + float b; }
not working
int addTwo (float a, float b) { float tree = 25.5; float house = 30.5; return a + b; }
not working
Jason Anello
Courses Plus Student 94,610 PointsThe very first one is perfect and will pass the challenge.
Thanks for hanging in there and figuring it out!
If the first one is not passing for you then I would try refreshing the challenge and pasting it back in.
Basilio Guzmán
Courses Plus Student 1,302 PointsThe first one doesn't work. Try to check the challenge.
Jason Anello
Courses Plus Student 94,610 PointsI just checked it again and it works. You may be having a challenge problem. Did you try refreshing the challenge?
This is passing for me:
float addTwo (float a, float b) {
return a + b;
}
I tried it twice.
Basilio Guzmán
Courses Plus Student 1,302 PointsI guess that not refreshing it was my problem, because now it works. BIG THANKS :D Now I have more reason to stay at Treehouse.
Jason Anello
Courses Plus Student 94,610 PointsYou're welcome! Glad you got it working.
It seems to be rare and I don't know if this is what happened to you but occasionally a correct answer will not pass the challenge. I think it's happening when you start off with a wrong answer and then correct it. What I would do whenever you think this is happening is to copy your code, then refresh the page and paste it back in and see if it passes.

Were you able to get started at all?
