This is illegal in both C and C++, and will compile in neither.

To pass an array and preserve its array type, just use a reference:
     void proc(char (&array)[156]);

Into this you can pass only conformant arrays, not arbitrary char *s.
Naturally this would normally be written as a template
     template<typename T, unsigned N> void proc(T (&array)[N]);
in order to have it work for arbitrary array types and sizes.

OK, I will.
