What happens when an object is destroyed that doesn't have an explicit destructor?

Question

explain with example in c++..

Answer 1

Destructor synthesizing is done by a compiler of an object’s class.
For instance, if an object of a class Sample is destroyed without invoking the destructor explicitly, the compiler synthesizes the destructor which destroys the object of the class Sample.

This process is done by invoking

Sample::~Sample().
