Apart from the Learn Java app, what books and internet resources would any helpful person on this forum suggest to a college freshman(me) taking intro to CS, and struggling? Right now, I'm struggling with writing my own for loops and nested for loops. I'm really confused. Usually, I'm very good coming up with solutions to analytical problems, but intro to CS is making me feel really dumb. I sincerely need help.

just asking. in C++, why do we need to define signed & unsigned integer? why don't we always use signed? it's better. we can freely assign plus and minus. so what's the catch of using unsigned?

While prototyping friend functions in a class is it necessary to always pass the address of the object as parameter?If so why is it that we have to pass address as parameter..In programs involving compositions we never used addresses...Why is the need for address of the objects while using friend?

I need to design a recursive function called replicate recur which will receive two arguments: times which is the number of times to repeat and data which is the number or string to be repeated. The function should return an array containing repetitions of the data argument. For instance, replicate_recur (3, 5) should return [5,5,5]. If the times argument is negative or zero, return an empty array. If the argument is invalid, raise ValueError.
