Array of Pointers to Objects

We can create an array of objects using pointers. For this we can use following syntax.

classname *pointer_var[size];

WAP to demonstrate array of pointers to objects

#include<conio.h>
#include<iostream.h>
class emp
{
char name[20];
float age;
public:
void getdata( );
void putdata( );
};
void emp::getdata( )
{
cout<<"\n\nEnter name and age of employee";
cin>>name>>age;
}
void emp::putdata( )
{
cout<<"\n\n\t"<<Name is--->"<<name<<"\tAge is--->"<<age;
}
void main( )
{
emp lct[3];
emp *lect[3];
int i;
for(i=0;i<3;i++)
{
lect[i]=&lct[i];
}
for(i=0;i<3;i++)
{
cout<<"\n\tEnter Details of Lecturer"<<(i+1);
lect[i]->getdata( );
}
cout<<"\n\tInformation about of employee";
for(i=0;i<3;i++)
{
lect[i]->putdata( );
}
getch( );
}


Output:-
Enter Details of Lecturer 1
Enter name and age of employee Irawen 101
Enter Details of Lecturer 2
Enter name and age of employee Pirawen 102
Enter Details of Lecturer3
Enter name and age of employee Ntirawen 103
Information about of employee
Name is---> Irawen        Age is--->101
Name is--->Pirawen       Age--->102 
Name is--->Ntirawen     Age--->103
