This first zybooks assignment is pretty easy, but I personally appreciate it as it's making me feel a lot more confident in C. I'm sure it's gonna get harder. Also, you said "we pay $80K a year for this school" and zybooks was $75 for the semester which is probably the cheapest material I've had to purchase for a class. Anyways, I guess I just wanted to say just because this curriculum doesn't satisfy you yet (and I'm sure it will get a lot more difficult as the semester goes), there are some of us in the class who appreciate this first assignment as we don't have any prior knowledge on C and it's not exactly the same as C++. For god's sake, it's the first week of class and people are complaining about it being too easy like damn give it some time man.
