Singly Inheritance program in C++

Example:

#include<iostream.h>

#include<conio.h>

class teacher

               {

                              private :

int id;

char name[20];

public:

void get();

void put();           

};

void teacher::get()

{

               cout<<”Enter teacher Info = ”;

               cin>>id>>name;

}

void teacher::put()

{

               cout<<” teacher Info = ”;

               cout<<id<<name;

}

class principle: public teacher

{

double salary;

public:

void getdata();

void putdara();

};

void principle :: getdata()

{

               cout<<”Entry Salary = ”;

               cin>>salary;

}

void principle :: putdata()

{

               cout<<salary;

}

void main()

{

clrscr();

principle p;

p.get();

p.getdata();

p.put();

p.putdata();

getch();

}
