Y2k - Code !!top!!

Since -30 is not greater than 65, the system calculates that a 70-year-old person is actually minus 30 years old . The pension notice is never sent. Worse, for credit cards, an expiration date of "00" (2000) would be interpreted as 1900. The code would assume the card expired 100 years ago and instantly reject every single card swiped on January 1, 2000.

The Y2K code was a result of the limitations of early computer systems. In the 1960s and 1970s, computer memory was extremely limited, and programmers had to be mindful of every byte of storage. To save space, they used two-digit date representations, which seemed like a reasonable solution at the time. As computer systems evolved, the two-digit date format was often retained, even as storage capacity increased. y2k code

: The primary fear was that when the date changed from December 31, 1999, to January 1, 2000, computers would interpret "00" as 1900 rather than 2000. Since -30 is not greater than 65, the
