Assignment Examples Final 07 Oct

  1. 1. The server where corresponding programs have been put is 10.203.161.7 under ~/CPP/ directory. Session 1 - 2: 1> Write a library class having public and private data members and functions. The class should allow basic operations like entering book details, displaying book details. Instantiate objects of this library class and perform operations on them. 2> Write a Intgr class to imitate the behavior of an int object. Define add, subtract and multiply class members for this class. Instantiate objects of this class and perform addition, subtraction and multiplication operations on them. 3> Implement a resource allocator using the concept of static data member and static member function. A Resource class should have a static data member to keep track of resource allocation (Boolean variable). Instances of this class will be allocated resource only if no other instance is holding the resource. Session 3 - 4: MEMORY OPERATIONS USING NEW DELETE 1> Write a program to copy data from one int array to another. Use the concept of new and delete to allocate and deallocate memory for the arrays. PASS BY REFERENCE 1> Passing by reference is also an effective way to allow a function to return more than one value. Write a program that returns the previous and next numbers of the first parameter passed using the concept of pass by reference. 2> Write a program to sort two numbers using call by reference. Smallest number should be output first. CONSTRUCTOR & DESTRUCTOR - DYNAMIC MEMORY – COPY CONSTRUCTOR
  2. 2. 1> Write a box class with class members length, breadth, height and a function to calculate the volume of the box. Constructor should be passed arguments for length, breadth, height. Also define a second constructor which takes default height value of 10. 2> Write a class with a “int *” member function whose constructor takes a int argument and allocates memory using “new” and destructor frees that memory. Note : Copy constructor should also be defined for this class. 3> Write a class with a simple integer as class member and a member function that returns that value. There should be two overloaded constructors one which takes an integer as argument and the other taking a “char *” as argument. Note : Can use atoi function to convert “char *” to int. Session 5 - 6 - 7: 1> Write a base class with protected class members length and breadth. Derived class should have a function to calculate the area using length and breadth of base class. inheritance/inheritProtectedCalcArea.cpp 2> Write a base and derived class with simple integer class members. Implement concept of base class constructor initialisation in the derived class constructor. Both the classes should have member function to display their class member values. This method should be protected in the base class and invoked from the base class. inheritance/inheritBaseMemInit.cpp 3> Implement multiple and multi-level inheritance. Derived class derived should have protected and private inheritance from base classes base1 and base2, where base1 and base2 have protected data members. Derived class derivedL2 should in turn publicly inherit from class derived. Try and access protected data members of base1 and base2 classes in derivedL2. Write destructor functions to see the sequence of destructor calls. inheritance/multiInherit.cpp
  3. 3. 4> Implement concept of virtual function using base class named Window and derived class named CommandButton. Base class will have a virtual member function named Create which should be over ridden in derived class. In the main function, declare two base class pointers, one should invoke the base class Create function and the other should invoke derived class’s Create function. Inheritance/virtualGeneral.cpp 5> Write a friend function for a class A to access it’s private data and compute addition on it’s private data. Similarly, write a friend class for this class A which accesses it’s private data and computes some subtraction on it’s data. Inheritance/friendFunction.cpp , friendClass.cpp Session 8 -9 - 10: 1> Write an overloaded volume function to calculate the volume of a cube (side*side*side), a cuboid (l*b*h) and a circle. 2> Overload the ‘+’ operator to add two user defined objects. 3> Define a person class with class members as name and age. Define a member function “greater” which takes one parameter (object of class person) as function argument. The function should compare the ages of two persons and return the object whose age is greater. Achieve the above using “this” pointer. 4> Define a class shape with 2 data members to store length and height. Define member functions get_data() and display_area(). Display_area() should be virtual function. Define 2 derived classes from shape, triangle and rectangle which redefine display_area() for their own specific area calculation. 5> Extend the above program to calculate are of a circle by introducing a new derived class called circle. The get_data() function in the shape class can be modified by taking default value for the second parameter.
