Let’s assume we have a class ‘Arithmetic’ with two member functions Add() and Subtract(). Suppose Add() function is defined within class then how will the subtract() function be defined out of the class boundary. Explain it with the help of some suitable program. 

Q.No.4 Sony TV Manufacturer want you to design a program that will help their customers to check the price along with the dimensions for their products to be purchased. For this Carefully read all the instructions and follow the requirements. o Create a class called SONY_TV along with two constructors as follows: o A Default constructor to set the length of TV. o A parameterized constructor that will receive the width in float. o By using a friend function calculate the area of the SonyTV o Create a member function to calculate the price of the sony TV by multiplying the area with Rs 100. o Create a show( ) function to show the details of the purchased sony TV. In the main you will construct three objects that will show the use of the two constructors. After calling the constructor it will call the area function, and then the price calculation function.

A designer in 3D graphics company wants to design a matrix as a two-dimensional array. The size of 2D array could be the last two digit of arid number. Initially he creates a class matrix that provides the member function to check that no array index is out of bounds. Make the member data in the matrix class a 10-by-10 array. A constructor should allow the programmer to specify the actual dimensions of the matrix (provided they’re less than 10 by 10). The member functions that access data in the matrix will now need two index numbers: one for each dimension of the array. Here’s what a fragment of a main() program that operates on such a class might look like:

If my Arid Number is 20-Arid-254 then: // in case of zero consider next digit

matrix m1(5, 4); // define a matrix object

int temp = 12345; // define an int value

m1.putel(7, 4, temp); // insert value of temp into matrix at 7,4

temp = m1.getel(7, 4); // obtain value from matrix at 7,4

Define a class called token number that incorporates a token’s number (could be the last 3 digits of your arid number) and its location. Number each token object as it is created. Use two variables of the angle class to represent the token’s latitude and longitude. A member function of the token class should get a position from the user and store it in the object; another should report the serial number and position. Design a main() program that creates three token, asks the user to input the position of each, and then displays each token’s number and position.

Write a C++ program to announce student’s result. Demonstrate this scenario through three classes: Students, Results and Examination. The Student class has data members {1st is roll number and 2nd is name}. Create the class Examination by inheriting the Student class. The Exam class input three subjects Marks out of 100 (OOP, English,Maths). Derive the child class Result from the Exam class and it has its own fields such as total Marks. Based on the total marks students must be declared pass or Fail if the total marks achieved by students equal or greater than 150/300 then only he be declared as Pass. Write an interactive program to model this relationship. (

Write a program to create Product class name and products are tv Boolean is Smart and mobile Boolean is 5G with

productID > 0,

name > 3,

MFGDate < Today,

ExpDate add 2 years,

price > 0,

Quantity > 0,

Tax > 1 and < 30 ,

Discount > 1 and < 50,

struct price GST -> Basic

Enume GST5 or GST8

override display()

in outpu:-

display

mfgDate,

ExpDate,

price,

ActualPrice = price + Tax - Discount,

TotalCost = ActualPrice * Quantity

Price.Get GSTPrice * Discount * Quantity
