#include <iostream>
#include <stdlib.h>

class t
{
public:
t()
{
printf("in constr");
}

private: // note that constructor is private here
~t()
{
printf("in destr");
}
};


int main()
{
t *t1 = new t; // create a new obj
delete t1; // delete the obj, which calls destructor
return 0;
}

Try to compile the above code.
following error results...

[root@localhost Desktop]# g++ test.cpp
test.cpp: In function ‘int main()’:
test.cpp:13: error: ‘t::~t()’ is private
tt.cpp:: error: within this context
[root@localhost Desktop]#

....implies, we can't have destructor private.

What is the difference between public, private, and protected access?
