cant understand the code.

Question

private bool GetBit(byte b int pos) { return ((b & (byte)(1 }

Vulpes · Answer

Basically if you number the 8 bits in a byte from 0 (least significant) to 7 (most significant) the method tells you whether the bit at position 'pos' is set or not. (byte)(1 If you're left with something which is non-zero the bit you're interested in must be set (true) but if it's zero then it isn't set (false).

. The leftshift operator is the equivalent of moving all the bits of a number a specified number of places to the left: private bool GetBit(byte b int pos) { return ((b & (byte)(1 } here you will pass value for b and pos you can about this better from this link http://www.c4learn.com/c-programming/c-bitwise-left-shift-operator/ after checking all condition it will return a value.

Suppose b = 0x05 and pos=2 '1' 00000001 shift '1' 2 positions gives 00000100 shifted '1' 00000100 b 00000101 & -------- result 00000100 Check if result is zero; if not return true else return false
