First power of 2

Question

Hello.i must write a program that reads the number n, from input and prints the first power of the number two, which is greater than n.

I have no idea for this. I just can use for,ifelse and I can't use any method or function or library.

Can you help me?

Answer 1

why not just start with a power of 2, check it against the input. If it's bigger print it, if not take 2 to the next power

Answer 2

Slick Thank you very much. It was a good idea and I wrote it.
