That is, printf("%d ",i); The format control character %d in means I shape the output;

The variable defined by long is 4 bytes, that is, 32 bits; The variable defined by int is 2 bytes, that is, 16 bits (on tc compiler).

65539 occupies 32 bits in memory, namely 000000000001000000001.

If it is to be output in plastic form, it needs to intercept 16 bits from the lower order and convert it into decimal output, that is, 0000000000 1 1. You always know what its decimal number is!

Have you just learned C language? Hehe, we were depressed when we first learned, but it's no problem. As long as you slowly ponder the knowledge in the textbook, you can certainly learn it well, and you will find it very interesting!
