It reminds me old early 2000s screen savers.

Every language has words for yes and no.

Assuming yes and no means true and false, c has numbers (1, 0) for yes and no and c++ can use those numbers for yes and no because it is a superset of c.

Technically, it’s 0 and non-0 but I always use 1. They are integers rather than keywords.

I would argue that he is not a programmer
