system in a very small scale. There are four classes, namely:

blood bank

Description of Classes:

variable named blood group which stores the number

of packets available in each blood group currently.

$5$ The Administrators can see the number of packets of

blood available for each blood group through the

admin class by entering the password.

$6$ Donors can login to enter their details and can donate

one, two or three blood packets.

$7$ Patients can login and borrow $1$ packet at a time.

Patients can borrow any of the compatible blood
