The first versions of ASCII used 7-bit codes, which meant they could attach a character to every binary number between 0000000 and 1111111, which is 0 to 128 in decimal.

In simple terms, the binary code converts all information into a code, a bit, that either can be a ‘on’ or ‘off’ - a ‘1’ or a ‘0’.

It is simple to convert candidate_number to its binary representation, as follows:. candidate = 1 << (candidate_number - 1). Checking if a candidate is present in the set. As mentioned above, the set ...

Technically, it isn’t a BCD (Binary Coded Decimal) watch. The minutes on this watch are displayed in pure binary, e.g., 32, 16, 8, 4, 2, 1, while if BCD, it would be 4, 2, 1 (tens digit), then 8 ...
