O2)

03)

Destructor is called when function is out of scope​

Answer 1

Answer:

1-The location of the object, that is, the exact memory location is passed, when the object is passed by reference.

2-Destructors are called when one of the following events occurs: A local (automatic) object with block scope goes out of scope. An object allocated using the new operator is explicitly deallocated using delete .

3-The destructor, and hence statement A, is executed as part of the processing of the return 0 statement B. This is a simple guarantee in C++, that the destructor of a local object with automatic storage, is executed automatically when the execution leaves the object's scope.
