Task: Implement a function named "addTwo" that returns the sum of two floats. The function will accept two float numbers as arguments and return a float which is the sum of the two arguments passed to the function. (No need to write the main function just write out the implmentation for the addTwo function)

My code:

float add_Two(float x, float y);

//int main float x = 3.3; float y = 7.2; add_Two(); //implementation float add_Two(float x, float y) { return x + y;

}

your code is correct (except the main method is a bit off) , but not what the challenge engine wants. It only wants the implementation of the method, not the prototype and not the main method. you also named the function add_Two instead of addTwo. so just use your implementation code and change the name like so:

 float addTwo(float x, float y) { 

    return x + y; 
}
