What I have tried:

I am supposed to create a code for binary conversion of int, I have the following code for char. I understand that char is 8 bits and int is 16 bits and I would need more shift operation to check " how many powers of two are there"

if I have 7 here would I have 14. could someone explain to me how these shift operators are set up. I understand they are checking the power of two but how are they doing it and if yes how can I apply this to higher bits. how do i set up shift operators?
