iOS Development - OBJ C - Functional Programming in C - Functions - Objective - Task

Trying to complete the challenge task in Functions. I have the code below. What am I doing wrong?

float addTwo(float a, float b);

int main() {
    float a = .5;
    float b = .5;
    printf("%f\n", addTwo(a, b));
    return 0;
}

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

I believe the instructions ask you to just write the implementation. This means that you have to assume that the declaration has been done for you. You also set values for the floats in main and printed the return value, which is unnecessary. Try this: 

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