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)
whattttttttt lol not even with the video....

returnType functionName(datatype argumentOne, dataType argumentTwo) {
return something;
}
the name of the function needs to be addTwo. the return type needs to be a float, as do your two parameters. you need to return the sum of the two parameters in the function body.

42,016 Pointsremember that this is c, not javascript, so you would need datatypes on your function parameters as well as your sum variable. You are also missing the return type of the function, but the logic of the function is correct

42,016 Pointsmost of the challenges contain material that isnt covered directly in the videos. They contain concepts covered in the videos, but you will have to think out the answer on your own using knowledge gained from watching. some of them can be pretty challenging (this one for example). If you have trouble understanding the concept of the challenge I find it best to go back and watch the first video or 2 that occur before the challenge
