Question

I am always confused between those two operators, I don’t know what makes
the number lower or larger.

Someone can tell me how to remember what each of those operators does? (Signs, some examples and etc.)

Answer 1

Think of them as arrows that ‘push’ bits up or down the number.

The << operator will increase the size of the number by pushing bits up towards the higher value slots in a byte, for example:

128  64  32  16  8   4   2   1
-------------------------------
 0   0   0   0   0   1   0   0    before push (value = 4)
 0   0   0   0   1   0   0   0    after << push (value = 8)

The >> operator will decrease the size of the number by pushing bits down towards the lower value slots in a byte, for example:

128  64  32  16  8   4   2   1
-------------------------------
 0   0   0   0   0   1   0   0    before push (value = 4)
 0   0   0   0   0   0   1   0    after >> push (value = 2)
