The difference between
21...in char a[]="string";
22... in char *p="literal";

is

in char a[]="string";, the memory is allocated, so the
value can be changed, it can be incremented, etc.

where as in char *p="literal";, you can just read it, may
be you can increment the pointer to point to the next
location, the content cannot be changed since this is a
string literal or BSS (Block Started by Symbol). This is
often called "const_data" or "data_const", or "literal".

23. *p++ it gets the content, and then increments the
pointer to the next location.

eg:

char a[] = {"string"};
char x;
char* p = (char*) a;

x = *p++;

printf ( "%c\n, %s\n", x, p );

output
