Overloading binary and unary operators in C++ programs

We are working on overloading of operators in C++ programs. In the following program both unary and binary operators are overloaded . I think this C++ program would help students. 

#include< iostream.h >

#include< conio.h >

#include< stdio.h >

#include< string.h >

class Count

{

private:

char str[40];

char address[40];

int age;

public:

Count()

{

strcpy(str,"***");

strcpy(address,"!!!!");

age=0;

}

void operator ++ ()

{

cout<< "\nEnter Your name:-";

gets(str);

}

void operator--()

{

cout<< "\nEnter your address( Town/City):-";

cin>>address;

}

void operator +()

{

cout<< "\nEnter your age:-";

cin>>age;

}

void operator -()

{

cout<< "\nName="<< str;

cout<< "\nAddress="<< address;

cout<< "\nAge="<< age;

}

};

void main ()

{

clrscr ();

Count c1;

char ch;

cout<< "\nWant to enter name (y/n):-";

cin>>ch;

if(ch=='y')

++c1;

cout<<"\nWant to enter address (y/n):-";

cin>>ch;

if(ch=='y')

--c1;

cout<< "\nWant to enter age (y/n):-";

cin>>ch;

if(ch=='y')

+c1;

-c1;

getch ();

}
