Stuck

Hi Guys, just got started yesterday and it all went pretty good so far but i'm stuck now. Could somebody explain what they are asking in a bit more detail?

This is the question:

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. (No need to write the main function. Just write out the implementation for the addTwo function.) __

My thoughts so far:

If I want to make a function like this I have to know the two floats right?

Any help or further explanation is greatly appreciated.

Br, Tim

Imagine you have two existing floats already, for arguments sake:

float a = 1.1; float b = 2.2;

Now just write the rest of the code that would return the sum of these in the challenge (I'll include an example in case I'm not being clear).

Your code in the challenge should look similar to this:

float addTwo (float a, float b);

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

Whoops sorry someone already answered (since I can't delete this I'll just leave it here)

You don't really need to know the values, all you need is a variable for them, and you can define your function in terms of those variables. For example, say you name your variables a and b, the function should look like 

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

Just need to add the type for the variables depending on the language you want to code it on.
