Bit shift operators c
WebAssuming your byte1 is a byte(8bits), When you do a bitwise AND of a byte with 0xFF, you are getting the same byte.. So byte1 is the same as byte1 & 0xFF. Say byte1 is 01001101, then byte1 & 0xFF = 01001101 & 11111111 = 01001101 = byte1. If byte1 is of some other type say integer of 4 bytes, bitwise AND with 0xFF leaves you with least significant …

Use the bitwise OR operator ( ) to set a bit.number = 1UL << n; That will set the nth bit of number.n should be zero, if you want to set the 1st bit and so on upto n-1, if you want to set the nth bit.. Use 1ULL if number is wider than unsigned long; promotion of 1UL << n doesn't happen until after evaluating 1UL << n where it's undefined behaviour …
