Answer:
Step-by-step explanation:
A destructor is called when there is a need to destruct or delete the object that is already created. As a Constructor is used to create an object, similarly a destructor is used to destruct the object. As there will be a default Constructor which is called when creating a new object, the default destructor is called to Destruct the object when the object goes out of scope or the function ends or program ends or a block containing that particular local variable ends or a delete operator is called.Examples for the destructor are (as the destructor contains delete operators )
Examples : delete []s ; In this example when the destructor is called, the delete operator will be called and the object created destructs.
