WebSep 7, 2012 · The closest you can come to an "array of bits" is an array of boolean. Each boolean will have a value of 0 or 1 (like a bit) but will probably take up 8 bits of memory space: boolean array [] = {true, false, true, 1, 1, 0, HIGH, LOW, LOW, HIGH}; // ten boolean values. I have a question as I'm always learning more. WebJan 28, 2024 · So we can get the byte number by simply dividing (integer division, mind, Python3 users beware) the input index by 8. In the case of 20 mentioned earlier then, we have 20 / 8 = 2 as our byte index. To get the bit within that byte, we then need to calculate the remainder of that same division, mod ( 20, 8) = 4.
