About character pointers in C

Question

Consider this definition:

char *pmessage = \"now is the time\";

As I see it, pmessage will point to a contiguous area in the memory contain

Answer 1

When you write: char *pmessage = "now is the time";

The compiler treats it as if you wrote:

 const char internalstring[] = "now is the time";
 char *pmessage = internalstring;

The reason why you cannot modify the string, is because if you were to write:

 char *pmessage1 = "now is the time";
 char *pmessage2 = "now is the time";

The compiler will treat it as if you wrote:

 const char internalstring[] = "now is the time";
 char *pmessage1 = internalstring;
 char *pmessage2 = internalstring;

So, if you were to change one, you'd change both.
