class - Where C++ calls destructors? -


assuming member , mylist 2 user defined classes. in following code:

void filllist(mylist &list1) {     member m1("aaa");     member m2("bbb");     list1.insert(m1);     list1.insert(m2);    }  void func1() {     mylist lst;     filllist(lst);     lst.printall(); }  int main() {     func1();     return 0; }

at point c++ call destructor of each m1, m2 , lst?

is safe assume c++ not remove object used again?

at point c++ call destructor of each m1, m2 , lst?

the destructors called @ end of scope, in reverse order of objects definitions. in case, func1() first called, defines lst, calls filllist(), defines m1 , m2. next filllist() ends, m2 m1 destructors called (in reverse order of declaration). func1() ends, lst destructor called.

is safe assume c++ not remove object used again?

i don't understand mean. destructed object gone, cannot use anymore. trying access (via dangling pointer/reference) undefined behaviour.
