arduino - Can you explain me (int i=0; i<8; i++, data>>=1)? -
i know loop needs in form of (initialization; condition; increment) in case there fourth part, know does?
there no fourth part. third part contains comma operator allows put various statements if 1 can't use {}
. pretty time i've ever used them (and while
) have single place want more 1 thing.
in case, last part of loop both incrementing (i++
) , shifting data
right once (dividing 2) @ end of each iteration
