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

Stage 2 Functions Challenge Task 1

Hey guys,

Bit stuck on this one..i got the code working in xcode but it doesn't accept it here, so i am obviously doing something wrong!

float addTwo(float a, float b);
    float one = 20;
    float two = 10;
    float floatTotal;
    floatTotal = one + two;
    printf("%f", floatTotal);

    return 0;

is what i have so far.

Any tips on this one?

Firstly you shouldn't use the values 20 and 10 since the numbers to be summed are a and b from the arguments list. Also don't return 0. Return your result. On top of that, the task doesn't actually require you to output the result, just return it. Therefore no printf is necessary in this task. :)

This might help - I was having trouble at the same place you were and it turns out I had a lot more code than necessary for the challenge
