Following is the a simple diagram for a class hierarchy of an employee, you are required to map the
diagram to C++ Code , Each class should have a default and an overloaded constructor and a function
named as SalaryCalculator() which calculates the pay according to the employee the employer have.
Parent class :Employee
Employee child classes:
1)SalariedEmployee
2)CommissionEmployee
3)HourlyEmployee
Employee and CommissionEmployee child class:
1)Base plus Commission Employee
Implement:
Inheritance
Dynamic Polymorphism
A main( ) which can test all the classes
Design a software system for FESCO-WAPDA for 2014 from which they calculate the monthly bill of
Electricity.
Write a class Bill having the following attributes and behavior
Int Units
Int per_unit_cost
Float bill
Pure virtual functions:
Monthly_bill()
Bill_display()
Derived the following classes from the base class Bill:
January_bill
February_bill
March_bill
April_bill
Perform the functionality:-
Calculate the monthly bills for every month.
Show the results on the console using Display () function.
Write destructor when you realize that this is the end of program.
Use virtual destructor concept in the above hierarchy.
Note:
Use virtual Member functions for derived classes.
Use appropriate values for per unit cost of monthly bills.
User appropriate data types.
Write a function that takes three int parameters a, b, c and returns the median of
the three numbers..
Why we study numerical method?
Design a class Cube which has following data members.
Length
Width
Height
A) Define a Member function of class
Set record () which sets record.
B) Also define following functions
Volume () (friend function) which calculates volume of cube.
Display () (friend function) which displays the data members and volume.
C) execute friend functions in main to execute different functionality
What are the states representing the following links:
a link
b visited
c hover
d active
Select the option that creates a sorted list. Where all Java program files are stored, in the folder
a <list>
b <dl>
c <ol>
d <ul>
Choose the correct option. Where all Java program files are stored, in the folder:
A.) bin
B.) scr
Find mistakes:
import java.applet.*;
import java. .*
public class Main extends JApplet
public paint (Graphics g) {
g.drawString ("Welcome in Java Applet!" , 40, 20);
}
}
(Abstract class, Interface, Method Overriding)Write a java program with proper
illustration to implement the following instructions:
e) Create a class Cat that extends Feline, then override the callSound() method and print
“meow” , also override the run() method and return 30.
f) Create a class Wolf that extends Canine, then override the callSound() method and
refer immediate parent class callSound() method , also override the run() method and
return 20.
g) Create a class Dog that extends Canine, then override the callSound() method, print
“woof” and refer immediate parent class callSound() method , also override the run()
method and return 10.
h) Create a class Main and write the main() method, then create object as-
Animals[] animals = new Animals[4];
animals[0] = new Cat();
animals[1] = new Dog();
animals[2] = new Wolf();
animals[3] = new Lion();
for i=0→animals.length: call animals[i].callSound() and analysis the outputs.
