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

I'm so confused

I don't know what I'm doing wrong... The instructions say that it doesn't need the int main() part of the program, but don't all programs begin like that? I'm just a little upset because I've been sitting here for over 3 hours trying to figure out what this objective wants of me. I keep on going back to the video and trying to understand what it is. I've even written it down on a piece of paper, but I'm not sure exactly what it wants now.

addTwo (float a, float b); { float a = 2; float b = 3; } add Two(float a, float b) { return a + b; }

shouldn't that be it?

This issue is all around the forum - there seems to be an issue with the challenge. You have the right answer. Move on and when the issue is fixed go back and do it to get your points. :-)

Hi Justyn,

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

would be ok but there ist a problem with the challenge at this very moment and you might want to have a look at Functions challenge

Kind Regards Holger
