Destructors in C++ with example

A destructor is a function that automatically executes when an object is destroyed. The prime usage of the destructor function is to release space on the heap. A destructor function may be invoked explicitly.

Example:

#include<iostream.h>

#include<conio.h>

class student

{

int id;

char name[20];

public:

void get();

void put();

~ student()                                        

               {

               cout<<”Object Destroyed”;

               }

};

void student::get()

{

               cout<<”Enter Student Info = ”;

               cin>>id>>name;

}

void student::put()

{

               cout<<”Student Info = ”;

               cout<<id<<name;

}

void main()

{

clrscr();

               student st;

               st.get();

               st.put();

               getch();

}
