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

FLOAT..!! it is not accepting my code, and I don't get what I'm doing wrong...

well, I've tried everything, and maybe it's just that I'm not quite understanding what I'm being asked for (English is not my first language...)

this is what they are asking:

"Implement a function named "addTwo" that returns the sum of two floats. The function will accept two float numbers as arguments. It should add the two arguments together, and return the result. (No need to write the main function. Just write out the implementation for the addTwo function.)"

I'll paste my code down here and if you could help me out a little I would seriously appreciate it.

float addTwo (float a, float b);
    float a = 24;
    float b = 35;

    float result = a + b;
    printf("a + b = %f\n", result);

    return a + b;

thanks a lot...!!

You just need to implement the function, not add parameters to it or anything like that. And remember, the body of a function must be surrounded in curly braces:

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

thanks a lot, I was just complicating myself after having tried so many different things...

You need to write a function that will add the two passed parameters. Something like this:

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

and then just call addTwo(1.2, 2.1);
