You've misunderstood then.

But * and [] types are modifable:

    char* s = "ABC";
    puts(s);
    *s = 'Z';

This shows ABC the first time it's executed. The second time it shows 
ZBC; the code has changed the string literal! Where the same literal iS 
shared across the program, it will change the value of "ABC" everywhere.

This is on those implementations that don't put ABC into readonly memory 
(eg. tcc, bcc, DMC, lcc, msvc). Ones like gcc and clang will crash.

You can't compare that with this:

   char t[] = "ABC";
   puts(t)
   t[0] = 'Z';

Here, "ABC" is left unmolested. But the reason is because the 
initialisation /copies/ the literal string to the array. So it modifies 
a copy. The declaration of s directly points it to the literal.
