# Not really sure what the question is asking tbh.

functions.c
```void addTwo(x,y){
float sum,x,y;
sum = x + y;
return sum;
}
```

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.)

you are close, however you have some errors:

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

in your function above, you have a return type of void (which means it does not return anything), however you should return a float.

also, your parameters are missing their types.

in the first line, you declare a float called sum, and then two floats x and y. you dont need to declare the floats x and y, they are already declared as parameters.

here is a shell of what your function should look like:

```returnType functionName(dataType parameterOne, dataType parameterTwo) {

return something;

}
```

using the function above as a guide, we can implement a function that returns a float, has 2 float parameters, and returns the sum of the 2 parameters:

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

}
```

Wow thanks a lot! :)
