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

functional programming challenge-ios

“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 can't seem to pass this challenge. My current code looks as followed

int addTwo(float a, float b); { float foo = 23 float bar = 54 printf("addTwo %d\n", addTwo(foo, bar)); } int addTwo(float a, float b) { return a +b; }

I put this into Xcode and it seems to work fine??

thanks for taking the time to read this

Peter

sorry looks more like this:

int addTwo(float a, float b); { float foo = 23 float bar = 54 printf("addTwo %d\n", addTwo(foo, bar)); } int addTwo(float a, float b) { return a +b; }

Hi Peter,

The challenge only wants you to write the implementation of the function. This is the last part of your code. Also, the function has to return a float, not an int.

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

ahhhh thanks Jason!! I now understand it. Im just starting out with coding so still struggling a bit haha. cheers man.
