Question

char *sample = "String Value";

&sample is a pointer to the pointer of "String Value"

is the above statement right?

If the above statement right, what is the equivalent of &sample if my declaration is

char sample[] = "String Value"

Answer 1

In the first one, there are two objects being created.

One is a char * (pointer-to-char) called sample, and the other is an unnamed array of 13 chars containing the characters of the string. In this case, &sample gives the address of the object sample, which is the address of a pointer-to-char – so, a pointer-to-pointer-to-char.

In the second example, there’s only one object being created; an array of 13 chars called sample, initialised with the characters of the string. In this case, &sample gives the address of the object sample – so, a pointer-to-array-of-13-chars.

In the second example, there is no “equivalent” to &sample in the first example, in the sense of a pointer-to-pointer-to-char value. This is because there is no pointer-to-char value to take the address of. There is only the array.
