Sequence Sum
A sequence of integers such as 1, 3, 5, 7,... can be represented by a function that takes a non-negative integer as parameter and returns the corresponding term of the sequence. For example, the sequence of odd numbers just cited can be represented by the function
int odd(int k) {return 2 * k + 1;}
Write an abstract class AbstractSeq that has a pure virtual member function
virtual int fun(int k) = 0;
as a stand-in for an actual sequence, and two member functions
void printSeq(int k, int m);
int sumSeq(int k, int m)
that are passed two integer parameters k and m, where k < m. The function printSeq will print all the terms fun(k) through fun(m) of the sequence, and likewise, the function sumSeq will return the sum of those terms. Demonstrate your AbstractSeq class by creating subclasses that you use to sum the terms of at least two different sequences. Determine what kind of output best shows off the operation of these classes, and write a

- in c++ write aprogram to Create a class Rectangle with length and breadth as private data members and also provide the following member functions: getdata(): gets the length and breadth of rectangle. calarea(): return the area of the rectangle. calperi(): return the perimeter of the rectangle. issquare(): return true if the rectangle is squarearrow_forward(Enhanced Employee Class) Modify class Employee inFigs. 12.9–12.10 by adding a private utility function calledisValidSocialSecurityNumber . This member function shouldvalidate the format of a social security number (e.g., ###-##-#### , where # is a digit). If the format is valid, return true ;otherwise return false .arrow_forwardAn abstract class a. Cannot be used to declare pointers and references b. Has at least one pure virtual function c. Can be instantiated d. Cannot have any constructorsarrow_forward
- Assume the definition of class foodType as given in Exercise 6. Answer the following questions? (1, 2, 3, 5, 6) Write the definition of the member function set so that private members are set according to the parameters. The values of the int and double instance variables must be nonnegative. Write the definition of the member function print that prints the values of the data members. Write the definitions of the member functions getName, getcalories, getFat, getSugar, getCarbohydrate, getPotassium to return the values of the instance variable. Write the definition of the default constructor of the class foodType so that the private member variables are initialized to 0, 0. 0, 0, 0. 0, 0. 0, respectively. Write the definition of the constructor with parameters of the class foodType so that the private member variables are initialized according to the parameters. The values of the int and double instance variables must be nonnegative. Write a C + + statement that prints the value of the object fruit 2. Write a C++ statement that declares an object my Fruit of type foodType, and initializes the member variables of myFruit to Apple, 52, 0. 2, 10,13.8, and 148.0, respectively.arrow_forwardComputer Science Create an inheritance hierarchy of Rodent: Mouse, Gerbil, Hamster, etc. In the base class, provide methods that are common to all Rodents, and redefine these in the derived classes to perform different behaviors depending on the specific type of Rodent. Create an array of pointers to Rodent, fill it with different specific types of Rodents, and call your base-class methods to see what happens. Write a small program to show the difference between calling a virtual function inside a normal member function and calling a virtual function inside a constructor. The program should prove that the two calls produce different results.arrow_forwardimplement all approprate member functions of a classarrow_forward
- Declaring a class virtual transforms it into an abstract class. T/Farrow_forwardObject Oriented Programing Consider the following details of all classes: Person Student Employee Administration Dean/HOD A person can be an employee or a student. An employee may have rights of admin officer or of academic officer. These class hierarchies represent multi-level inheritance. However, a Dean or Head of Department(HOD) may have rights to modify the status already defined by an administrator academic officer. Implement all these classes with appropriate data members and proper suitable functions and within the main function, create instances of all classes and test the described working of all these classesarrow_forward(HugeInteger Class) Create a class HugeInteger that uses a 40-element array of digits tostore integers as large as 40 digits each. Provide member functions input, output, add and subtract.For comparing HugeInteger objects, provide functions isEqualTo, isNotEqualTo, isGreaterThan,isLessThan, isGreaterThanOrEqualTo and isLessThanOrEqualTo—each of these is a “predicate”function that simply returns true if the relationship holds between the two HugeIntegers and returns false if the relationship does not hold. Also, provide a predicate function isZero. If you feelambitious, provide member functions multiply, divide and modulus.arrow_forward
- Define access private member of a classarrow_forwardUsing the scenario of Object oriented programming oop Q 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…arrow_forwardWe discussed in the class that during the design, you may need a class that serves as an interface for its derived classes, but you would not create any instance of that class. Such a class is called an abstract class. The UML class diagram shown below shows a class hierarchy starting from the Vehicle class which is an abstract class. Write a program to implement this class hierarchy such that the given code in the main function runs without error. Vehicle Bus Car Truck IntraCityBus InterCityBus int main() { Vehicle* V[] = { new Bus, new Car, new Truck, new IntraCityBus, new InterCityBus }; for (int i = 0; i < 5; i++) { cout<< V[i]->move() <<endl; } return 0; } Your program should produce an output as the following: Bus: Moves to carry a large number of people Car: Moves to carry a small number of people Truck: Moves to transport goods Intra-City Bus: Intra-City Bus: Moves to carry a large number of people between two areas of a city Inter-City Bus:…arrow_forward
