In objective c basics stuck on this challenge . cannot go any further and unlike codeschool this won't give you any hint

Maybe I can help you out a bit here. The challenge is asking you here to implement a function that adds up two float variables without writing out the main function, which could be tricky considering the call to the addTwo function needs to be named in the main(). I will be using the // to make comments as you would in the code.

// Firstly, we need to define the two floats. I made up the numbers in this example. Normally these are defined in the main function before the call for the addTwo function is made


float firstNumber = 2.512342;
float secondNumber = 4.523453;

// Now here is where we implement the 'addTwo' function which would be theoretically located outside of the main(). FYI, you see the ';' missing at the end of the function? That is correct, it's not a typo.

float addTwo(float firstNumber, float secondNumber)

{
float sumOf = firstNumber + secondNumber;
return sumOf;
}

That's basically it. I haven't gotten to that challenge yet in my progress so I wouldn't know how they want it written out (the video might give some context as I've noticed that the challenges are nearly identical to the content of the respective video). But I'm also studying another book on C and Obj-C and I'm a bit further than where you're at right now. Hope this helps.
