Question

Is it good to send stack allocated object as a pointer parameter to some other function?

Answer 1

Yes, but the more common C++ idiom for this situation is to use a reference (and probably a const rreference) instead of a pointer. So instead of

void foo( sometype * p ) {    p->func(); } 

you write:

void foo( sometype & p ) {    p.func(); } 

This has the advantage that you don’t need to dereference the object in the caller:

void afunc() {    sometype t;    foo( t ); } 

and also gives a subliminal hint to the reader that you do not intend the function to take ownership of the object.
