C Programming - Pointers - Discussion

This is a 2D array: static char*s[] = {"black", "white", "pink", "violet"};

This is an array of char**: char**ptr[] = {s+3, s+2, s+1, s} with first element at "violet".

p = ptr;

This will increment the pointer, in this case it will increment by 1 to the next array element i.e. pink: ++p;

This one has operator precedence also mixed with ++, so, it is actually (**p) + 1, remember all strings are NULL terminated, so it will print "pink" from "i" or "ink: printf ("%s", **p+1);

I want answer of printf("%s, *--*++p+3).

I still don't understand the difference between ** and * and ***. How do we say that by having ** the characters of the array are accessed?

I don't understand ***p step.

What is the use of static in the program?

Thank you all for great explanation.

s is a character pointer.

s[]:

s[0]=black.
s[1]=white.
s[2]=pink.
s[3]=violet.

ptr[]:

ptr[0]=violet.
ptr[1]=pink.
ptr[2]=white.
ptr[3]=black.

Here p=ptr i.e p, ptr are the same address.

++p is equal to ++ptr that means pink. For these p++ ia added the +1 that means ++p+1 that is **p+1 means ink.

How **p+1 means ink?

It refers second variable. And also gives output from second word of referred variable.

I can't understand. Please clrealy discuss.
