c# - Is it possible to restrict int value (set a range) using bitwise operations? -

i need have integer counter have values 1 6 inclusive in wrap around fashion. namely starting 1, count 6 , go 1. wonder if it's possible achieve using sort of bitwise logic. of course it's trivial if statement below wondering 1 liner :)

int counter = 1;  for...         if (counter++ == 7) counter = 1; 

addition: here why want 1 liner:

byte output = (byte)((inputbyte & 0xf8) | counter++); 

use modulo operator.

do something;     ++counter; counter %= 7; ++counter; 

to use real bitwise operations modulo must power-of-2 not case here.

ps: if counter started @ 0 instead of 1, wouldn't need second ++counter , write :

for (int counter = 0; (somecondition); ++counter, counter %= 7) {     something; } 

pps: note if performs faster modulo, tho.
