This method encapsulates data as the functions using this method does not need to bother or handle the infromation being displayed or the format in which it will display, all the function need to know is that the method returns a string value.

Constructors
Employee Class Constructor
Employee::Employee( $oid){ empID 5 4>4; name 5 4>4; IC 5 4>4; gender 5 4>4; designation 5 4>4; department 5 4>4; dateJoined 5 4>4; DO 5 4>4; nationality 5 4>4; religion 5 4>4; maritial!tat"s 5 4>4; 0
The constructor for the parent class &mployee that takes in no values.
Admin Class Constructor
*dmin::*dmin($oid):Employee() {0
-ince the +dmin has no new fields all the fields that it has is from the pa rent &mployee class which already has its own constuctor, therefor the +dmin class constructor just needs to call one of the parent class constructor, where in this example its the &mployee() constructor.
"# Class Constructor
'::'($oid):Employee() {0
-ince the $% has no new fields all the fields that it has is from the parent & mployee class which already has its own constuctor, therefor the $% class constructor just needs to call one of the parent class constructor, where in this example its the &mployee() constructor.

class Employee
class *dmin:p"#lic Employee class ':p"#lic Employee
rom the example above we can see that the class +dmin and $% inherits the &mployee class and since the the fields are set under the access modifier of protected and the method are under the the access modifier of public the two child classes has every field and method in them.

The since the &mployee class methods are inherited into +dmin class the gui'enu() method of &mployee class is overridden with the gui'enu() method in the +dmin class.
first need to download it.
*for &mployee class constructors Employee::Employee( $oid){ empID 5 4>4; name 5 4>4; IC 5 4>4; gender 5 4>4; designation 5 4>4; department 5 4>4; dateJoined 5 4>4; DO 5 4>4; nationality 5 4>4; religion 5 4>4; maritial!tat"s 5 4>4; 0
Employee::Employee(string empID3, string name3, string IC3, string gender3, string designation3, string department3, string dateJoined3, string DO3, string nationality3, string religion3, string maritial!tat"s3){
empID 5 empID3; name 5 name3; IC 5 IC3; gender 5 gender3; designation 5 designation3; department 5 department3; dateJoined 5 dateJoined3; DO 5 DO3; nationality 5 nationality3; religion 5 religion3; maritial!tat"s 5 maritial!tat"s3; 0
rom the example above we can see the constructors are for the same &mployee class but there are two of them, this is made possible by to overloading the constructors with different
parameters and different amounts of parameters to take in.

The designation can be specified in the designation.txt file and the designation’s access can be specify 8,9 or @ in front of the designation name without space and each 8, 9 and @ represents the +dmin account access, $% account access and :ormal staff account access.

The search just takes in one string but it has the ability to search all the fields for

Conclusion
Through out the assignment I have realiAed that even though "## is not as modern as Bava but "## has the ability to create large and complex systems due to the fact that it is an object oriented programming language. "## also has certain features other programming languages don’t have like pointers and operator overloading, these features have proved to be very useful over course of the assignment’s program development. I believe "## could be better if its library functions are more well developed like Bava’s +!I. ue to current growth of internet technologies I believe that "## as the most demanded programming language is soon to change, even so the use of "## to create a system has made me more knowledgeable on the field of software development
