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.

Edited by myk45: n/a

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.
