objective c functions and floats

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.)

this is my code what am i doing wrong and can you explain more in detail of what they are exactly asking for please. 

float addTwo(float a, float b);

    float a = 24.564;
    float b = 25.546;
    printf("%f + %f\n", float addTwo(a, b));
    return 0;


float addTwo(float a, float b) {

  retun a + b;

}

Hey Joel,

Your pretty close, there are a couple changes you need to make.

First, get rid of all this code on top:

float addTwo(float a, float b);

    float a = 24.564;
    float b = 25.546;
    printf("%f + %f\n", float addTwo(a, b));
    return 0;

You don't need it in the challenge.

Second, you have a typo in return. You spelt it retun, with no second 'r'. That should fix it.
