Here's a quick look at what you, or you students, will see when they attempt a problem in ClassCube.
On the right side is the instructions for this problem. Since it's a demo, the problem is pretty simple. You just want to return the sum of the two parameters, a and b.
On the left is your editor.
I intentionally make a couple of mistakes so you can see what that process looks like. Especially early programmers will make a lot of mistakes with their code.
Notice that even the first two failed attempts show that 1 out of the 4 tests passed. That's because 1 of the tests has both a and b set at 0, so simply returning 0 passes that particular test.
At the end you'll see the previous submissions menu where you can go back and look at all of your submissions for this problem.
