I wrote the whole function and I wrote it in Xcode too to be sure, still giving me wrong every time, yet in Xcode its ok

Can anyone tell me whats wrong with my function? because in Xcode runs successfully.

functions.c 
float addTwo ( float a, float b );

 {       
        float a = 3.2;
        float b = 4.2;

        float result = addTwo ( a, b );

        printf ( " %f  \n " , result );

         return 0;
}

    float addTwo ( float a, float b )


{
        return a + b ;
}

In your first version of the function, you can remove the semicolon in this line:

float addTwo ( float a, float b );

Also, inside that function, you don't need to re-declare float a and float b, you should just use the variables you declared in the function definition.

So, your final function would look like:

float addTwo ( float a, float b ) { a = 3.2; b = 4.2;

float result = addTwo ( a, b );

printf ( " %f  \n " , result );

return 0;

}
