Find the program below to demonstrate the composition.
first define the class called the DataBirth.
class DateOfBirth
{
public:
void UpdateDMY();
void GetDMY();
private:
int date,month,year;
};
define the Employee class.
class Employee
{
public:
void GetDetails();
void UpdateDetails();


private:
DateOfBirth BirthDate;
}
Here the EMployee class is having the object of the
DateOfBirth class as data member. With this the Employee
class is achieving the "has-a" relation with the
DateOfBorth class. In this way the Employee class can have
objects of the many calsses as members.
