Solved in 3 steps with 1 images
- Create parent class Shapes with protected parameters width and height and function printarea() and a virtual function cal_area(). Create two sub classes Rectangle and Sqaure. In main() create 2 pointers of Shapes and assign Rectangle and Square to it. Call printarea function with the pointers. Note: Use C++ language with well explaination. After performing this program. Implement this program using an abstract class.In C++, create a class student with member int ID and string name, and a default constructor that prints "Object created". Inside main create an object of student class.7. Write a program in the C++ language to create a class Rectangle with two member integer variables length and breadth. Write the parameterized constructor for the Rectangle class and also add a member function that displays the area of the rectangle in the output.
- c++ Write a C++ program to overload unary (++) operator. More specifically, create a class Increment with member variables a and b of type int. Create a function input() to take values of a and b from user. Make operator function to increment a and b by 1.Create a class in C++ called ADDITION has one integer and one float data member. Use pointer to data member to find their sum and print it from main method and also use the concept of dynamic constructor.(Using C++) Define a base class vehicle and its two derived classes :Car and Scooter. Write a program to ask the user for the type of vehicle and then using the concept of runtime polymorphism, display the message "It is a two-wheeler" for scooter and "It is a four-wheeler" for car.
- Write a program in the C++ language to create a class Rectangle with two member integer variables length and breadth. Write the parameterized constructor for the class and also add a member function that displays the area of the rectangle in the output.In C++, write a Number class that holds a double, and add overloaded operators for +, –, *, /, and assignment. Choose the return values for these functions so that expressions can be chained together, and for efficiency. Write an automatic type conversion operator intdouble( ).C++ a) Implement a class Animal.data members:type – an automatic variable (mammal, fish etc.)functions:accessor - an accessor for the type variableoutput() - output the type of animal b) Implement a class Human which is derived from Animal. data members:name - a dynamic variable (name of human)functions:accessor - an accessor for the name variableoutput() - redefined to output name and type
- 1. Write a program in the C++ language to create a class Triangle with three member integer variables side1, side2, and side3. Add the parameterized constructor for the class and add a member function findArea that displays the area of the triangle in the output.In C++ The base class Pet has private data members petName, and petAge. The derived class Dog extends the Pet class and includes a private data member for dogBreed. Complete main() to: create a generic pet and print information using PrintInfo(). create a Dog pet, use PrintInfo() to print information, and add a statement to print the dog's breed using the GetBreed() function. Ex. If the input is: Dobby2Kreacher3German Schnauzer the output is: Pet Information: Name: Dobby Age: 2Pet Information: Name: Kreacher Age: 3 Breed: German SchnauzerWrite a program in the C++ language to create a class Triangle with three member integer variables side1, side2, and side3. Write the parameterized constructor for the class and also add a member function that displays the area of the triangle in the output.
