When to use const char * and when to use const char []

Question

I know they are different, I know how they are different and I read all questions I could find regarding char* vs char[]

But all those answ

Answer 1

I was helped a lot by Ulrich Drepper's blog-entries a couple of years ago:

so close but no cigar and more array fun

The gist of the blog is that const char[] should be preferred but only as global or static variable.

Using a pointer const char* has as disadvantages:

1. An additional variable
2. pointer is writable
3. an extra indirection
4. accessing the string through the pointer require 2 memory-loads
