float function

I can't work out what is incorrect here. I have left out main function as suggested in the title. I can run this in xCode and it works (with int main () included), but I keep getting an error when checking the task on the Treehouse website.

float addTwo(float a, float b); { float foo = 22.6; float bar = 22.5; printf("Sum of floats is %f\n", addTwo(foo, bar)); return 0; }

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

The error is:

expected unqualified-id { ^ 1 error generated.

functions.c 
float addTwo(float a, float b);
{
    float foo = 22.6;
    float bar = 22.5;
    printf("Sum of floats is %f\n", addTwo(foo, bar));
    return 0;
}

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

Hi Tom,

All you need for this challenge is your second function as that is all the task is asking for.

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

Happy coding!
