Absolutely not. A C compiler in a relaxed diagnostics mode might allow
something like this, since C compilers by default are traditionally very
forgiving when it comes to pointer casts. However, such a conversion is
illegal from the language point of view. Any half-decent C compiler will
normally issue at least a warning about broken assignment.

Eh? Perhaps I didn't state that correctly.

char a[10];
char * b;

....

b = a; // compiles just fine
