Create the class Circle with attribute radius to find the area of circle. Assign the values for data member using copy constructor and display the result. Finally free the resources of data objects using destructor member function. (Note: Area of circle = 3.14 * radius * radius

Define the classes using hierarchy inheritance. An organization has two types of employees: Regular and Adhoc are derived class. Regular employees get a salary which is Basic salary + DA + HRA where DA is 10% of basic and HRA is 30% of basic. Adhoc employees are daily wagers who get a salary which is equal to Number oh hours * Wages amount. The employee base class consisting of member variables such as name and empid. When a regular employee is created, basic salary must be a parameter. When Adhoc employee is created wages amount must be a parameter. Define the member functions for each class and the member function days( ) updates number of the Adhoc employee

The postage for ordinary post is Rs. 2.00 for the first 15 grams and Rs. 1.00 for each additional 10 grams. Write a C++ program to calculate the charge of postage for a post weighting N grams. Read the weights of N packets and display the total amount of postage using multiple inheritance.

* Base class-1: Member variables are name, source and destination.

* Base class-2: Member variables are no. of packets and weight.

* Derived class: Member functions display(), displays the name, source, destination, total weight and total amount

Develop a code for the multilevel inheritance diagram given below

·         The person class consisting of data members such as name and age.

·         The salary details class consisting of data members such as salary.

·         The employee class consisting of data members such as degree and experience.

·         The manager class consisting of member function pfund() to find the employee provident fund satisfying the condition total experience to be greater than 10 and salary to be greater than Rs. 20,000 and then calculate net salary = basic pay + pf. The provident fund amount sanctioned is Rs. 1800 for basic pay Rs 20,000 otherwise provident fund amount sanctioned is Rs. 750

Design the class Vowel to find the number of vowels present in the given string. Define the constructor member function to assign the values and destructor member function to destroy the data objects

Define a class Fixed_Deposit with the following specifications, the program uses three overloaded constructors. The parameter values to these constructors are provided at run time. The user can provide input in the following forms.

   1. Amount, period and interest in decimal form.

   2. Amount, period and interest in percent form.

   3. Amount and period.

PRIVATE DATA MEMBERS:

P_Amount long int type Years integer type Rate float type R_value float type

PUBLIC MEMBER FUNCTIONS:

Fixed_Deposit() Null constructor

Fixed_Deposit(p, y, r=0.12) Parameterized constructor with default arguments to accept values for P_Amount, Years and Rate(in Percent e.g., 0.12, 0.09)

Fixed_Deposit(p, y, r) Parameterized constructor with default arguments to accept values for P_Amount, Years and Rate(in Decimal e.g, 12%, 8%)

display() Function to display the P_Amount and R_Value

~Fixed_Deposit() Destructor to destroy the data objects

Create the class Circle with attribute radius to find the area of circle. Assign the values for data member using copy constructor and display the result. Finally free the resources of data objects using destructor member function. (Note: Area of circle = 3.14 * radius * radius

Define a class Batsman with the following specifications:

Private members:

bcode 4 digits code number bname 20 characters innings, notout, runs integer type batavg it is calculated according to the formula – batavg =runs/(innings-notout) calcavg() Function to compute batavg

Public members:

readdata() Function to accept value from bcode, name, innings, notout and invoke the function calcavg(). displaydata() Function to display the data members

Design a class Calendar to calculate number of years, months and days. The member variables are nds, years, months and days. The member functions are d() which accepts number of days and display() to display total number of years, months and days.

Design class Seller to determine whether the seller has made profit or incurred loss. Also determine how much profit he made or loss he incurred. Cost price and selling price of an item is the data member of the class which is input data given by the user. Include the following member function

getItemDetails()- to get item details

dtermineProfitLoss()- to determine whether the seller has made profit or incurred loss

showItemDetails()- to get item details with Profit or loss.
