When a program starts its content copies from external
memory like a hard drive to a PROTECTED from writes part of
RAM. No any byte in that area can be changed!
Now the difference.
char * p = "this string is in protected memory and cannot be
changed";
You cannot change the string located in protected memory a
pointer points to.
char a[] = "this string is in memory that can be changed";
Theoretically char * p = "string"; eat less memory than
another one.
