Bitwise rotation (Circular shift)

Question

I was trying to make some code in C++ about “bitwise rotation” and I would like to make this by the left shif. I didn’t know how to code this, but I found a little code in “

Answer 1

You have more than 4 bits in your integer, most likely 32, but could theoretically be 64 or 16. So your bits for the value 12 are 00000000000000000000000000001100. Doing a left rotation by 1 would naturally give you the value 00000000000000000000000000011000 (=24).
