Implement a function named "addTwo" that returns the sum of two floats as arguments.

Implement a function named "addTwo" that returns the sum of two floats. The function will accept two float numbers as arguments. It should add the two arguments together, and return the result. I know this is very basic is simple yet it bothers me that why its not going through. I have also tried.. float addtwo(float a, float b) { a = 23; b = 34; return float a + b; }

functions.c 
float addtwo(float 10, float 21) {
    return 10 + 21;
}

You can't use actual numbers as function arguments in your function definition.

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

You are correct maybe, but dont use actual numbers. "x" and "y" instead

float addTwo = (x,y) { return x + y; };

:D Why is that they are not clear on that, it clearly say add two arguments. Also what is the purpose of having float in the parentheses (float a, float b). Is there another way this could have been done?
