Not sure how to do this, iOS problem

Not quite sure how to return the float value. There may also be some other areas i'm not doing correctly.

functions.c 
void addTwo(a,b){
  int here = a+b;
  printf("%s\n",here);
  return 0;
}

You'll want to return here since that is the value of the two parameters added together.

void addTwo(a,b){
  int here = a+b;
  return here;
}

Thanks Alex, but it says that I should also declare it a float somewhere.

read it too quickly you'll want your method to return a float not be a void

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