WebMar 5, 2015 · We use the expression (myByte & (1 << position)) != 0 to check if a bit is set. This works by using the Left Shift operator (<<) to take the value of 1 whose binary expression is suprisingly (heavy sarcasm) 00000001 to shift the bit to the index (0-7) which we want to check. Applying the Left Shift operator on the value of 1 looks like this: WebC-style bit-manipulation.
