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

Need help with this challenge

I don't understand where I am false. The compiler tells me that I should return a float but I think I already do so.

functions.c
int addTwo(float a, float b);

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

Hey alexandergross,

The problem with your code is that although your parameters are of float type, your function is still set to return an integer value. So you can replace the int data type in your function and replace it with float

float addTwo(float a, float b);

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

Hope this will solve your problem :)

Thanks for your help!
