[Starter Question] Difference between Binary value and normal value

[exclusive]

When I open a pdf file with binary format, what is the difference between opening it without b in fopen(,)?

Will Using char array to cap all the array be different from using char* array to cap all the array?

[MK27]

It's system specific, eg, on POSIX systems (such as linux), there is no difference.

An implementation need not distinguish between text streams and binary streams.

If it does distinguish, the binary stream is one that should be, byte for byte, identical to the data read. The text stream may be modified (eg, replacing '\n' with '\r\n').

Will Using char array to cap all the array be different from using char* array to cap all the array?

A char array would have the data in a single array. A char* array (array of pointers to char arrays) might be breaking it into lines, with each line in a char array.
