I wanna ask,
How can we reverse a number by using Recursive ?

For example if a number is 123, the result will be 321.
is that any idea to help me? because i can't think about it... i poor on this chapter.

Paste the code, of whatever you have tried. We can help you build on that. Well, here is a hint:

Let the number be N

rev_num = rev_num * 10 + (N % 10)
N /= 10

You need to do this till N becomes 0.

sorry that i have never do the code,
because im still stucking what should i put for my if-statement and else-statement.
i have no idea what should i put on that so i came over here to ask for help.

Well, in my previous post, i pasted a hint. based on that, give it a try. Use a loop and try. Then you can go for an iterative approach.

You can learn best when you try it on your own.
