Out of curiosity, why are we converting something to a char* when we write it to a ( binary ) file?
Because the typical I/O functions that write, take a pointer to
char. This is because someone considered that the most representative way of talking about the data stored in a binary file; it’s just a bunch of the machine’s smallest adressable word, in sequence. The C type name for that ischar.
