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

How do you implement a function that returns the sum of two floats? Stuck on the quiz.

The function will accept two float numbers as arguments, add them, then return the result.

here is a shell of what your function should look like:

returnType functionName(dataType argumentOne, dataType argumentTwo) {

    return something;

}

The challenge tells you the return type needs to be a float, the functionName needs to be addTwo, the data type for the two arguments should be float, and it should return the sum of the arguments passed in to the function

float addTwo(float 1, float 2,) { return 1 + 2;}

I'm sorry I'm just not understanding, forgive me for being a novice.

variable names cannot be numbers. change your variable names to one and two and remove the comma after your last argument.

float addTwo(float one, float two) { 
return one + two;
}
