Behavior of constructors and destructors in inheritance

 

For Example: Write a program to demonstrate the use of constructors and destructors  in inheritance.

#include<iostream.h>

#include<conio.h>

class base      //base class

{

public:

base()         //constructor

{

cout<<"Base class constructor"<<endl;

}

 

~base()        //destructor

{

cout<<"Base class Desctructor"<<endl;

}

};

 

class derived : public base           //Derived  class/ child class

{

public:

derived()                                                                                             //constructor of derived class

{

cout<<"Derived class constructor"<<endl;

}

 

~ derived()                                                                         //destructor of derived class

{

cout<<"Derived class destructor"<<endl;

}

};

 

int  main()

{

derived d; //Automatically executes both derived class and base class

 

getch();

return 0;

}

output :

Multiple Assignment and Data types

Image
  Multiple Assignment: Python programming language allow, you to declaration of multiple variable and its assign multiple value to the variables.   For Example:             X=y=z=10 Here, an integer object is created with the value 10, and all three variables are assigned to the same memory location. You can also assign multiple objects to multiple variables.             x,y,z = 25,35,”Ramakant” Here, two integer objects with values 1 and 2 are assigned to variables x and y respectively, and one string object with the value "Ramakant" is assigned to the variable z. For Example: Write a program demonstrates the use of variable. a = 55   #here a is variable of integer type b = 35 c = a + b print("Addition of two Number is=",c) welcome = "Welcome"    #here welcome is string variable aryan = " Aryan Computers, Barshi" welcome = welcome + " to " + aryan print(welcome) Output: This is how you cast one variabl

Pointer to the derived class and base class

Image
  For Example: Write a program to declare a pointer to the derived class and access the member variable of base and derived class. #include<iostream.h> #include<conio.h> class A { public: int b; void display() { cout<<"Value B is="<<b<<endl; } };   class B : public A { public: int d; void display() { cout<<"Value of B is ="<<b<<endl<<"Value of D is ="<<d<<endl; } };   void main() { B *cp; // here cp is pointer object derived class B b;    // here b is object of B class cp=&b;   //initialized simple object to pointer object cp->b=200; //Assign value to pointer object cout<<"CP points to the derived object"<<endl; cp->display(); //member function calling with the help of pointer object getch(); } Output:

Virtual Base Classes..

Image
  Virtual Base Classes:  Program: Write a program to demonstrate the use of Virtual Base Class #include<iostream.h> #include<conio.h> class student { protected: int rollno; public: void get_number(int a) { rollno = a; }   void put_number(void) { cout<<"Roll No:"<<rollno<<endl; } };   class test:virtual public student { protected: float part1,part2; public: void get_marks(float x, float y) { part1=x; part2=y; }   void put_marks(void) { cout<<"Marks Obtained:"<<"\n"     <<"Part1="<<part1<<"\n"                  <<"Part2="<<part2<<"\n";                  }     };   class sports:public virtual student { protected: float score; public: void get_score(float s) { score=s; } void put_score(void) { cout<<"Sports Score:"<<score<<endl; } };   class result:public test, public sports { float total; public: void display(void); }
