What am I doing wrong?

I hate to post the same question twice, but I am still having the same problem. Alright I don't know what to do when they ask me to return the sum of two floats. I get that I have to use the return function, but I don't get if I am supposed to write it with the "int" function or the "float" function. If anyone could help me out that would be greatly appreciated

Here is the code, I am using

float addTwo(float a, float b);
{

    float foo = 24;
    float bar = 35;
    float result = addTwo(foo, bar );
    printf("Add Two %d\n", result);

    return 0;
}

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

Okay so, you've written out a whole lot more than the challenge wants. It just wants the implementation of the addTwo function.

The float before the addTwo function tells the compiler that the function should return a float.

The word float before each argument tell it that each argument should also be a float.

You do not need to identify a data type when using "return".

The challenge tells you to miss out the main function part. so for the challenge you will just need to put the last bit:

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