To print the data members of an object along with a proper heading calls for writing considerable code. This can be made more efficient by overloading the extraction operator (<<). Following code shows how to overload the << operator:
#include <iostream.h>
#include <string.h>
class emp
{
private :
char name[25] ;
int age ;
char phone[15] ;
public:
emp ( char *n, int a, char *p )
{
strcpy ( name, n ) ;
age = a ;
strcpy ( phone, p ) ;
}
friend ostream& operator << ( ostream &cout, emp e ) ;
} ;
ostream& operator << ( ostream &cout, emp e )
{
cout << “\nName : ” << e.name << “\tAge : ” << e.age << “\tPhone : ” << e.phone ;
}
main( )
{
emp e1 ( “Prakash”, 24, “911-65289″ ) ;
cout << e1 ;
}
