Object Oriented programming language about Constructors (Part 2)

Constructors Part 2: 

3. Overloaded Constructor: The process of using 2 different types of constructor in a single program is called as overloaded constructor.

Program to understand Overloaded Constructor:

 #include<iostream>

 using namespace std;

   class simple

    {

   private :

   float p,n,r,s;

 public :

simple( )

    {

   p = 2000;

   n = 2.5;

   r = 3.2;

}

simple(float x,float y,float z)

   {

   p = x;

   n = y;

    r = z;

     }

   void show( )

    {

    cout<<"p : "<<p<<endl;

   cout<<"n : "<<n<<endl;

   cout<<"r : "<<r<<endl;

    }

   void process( )

    {

    s = (p * n * r)/100;

    }

   void output( )

    {

   cout<<"Simple Interest : "<<s<<endl;

    }

    };

int main( )

{

simple s,x(3000,2,5);

s.show( );

s.process( );

s.output( );

x.show( );

x.process( );

x.output( );

return 0;

}

4.Copy constructor:  It is used to declare and initialise the object from another object.

Program to understand Copy Constructor:

  #include<iostream.h>

  using namespace std;

  class copy

  {

  private :

  int a;

  public :

 copy(int x)

  {

  a = x;

  }

  void show( )

   {

   cout<<"The value of a : "<<a<<endl;

   }

   };

   int main( )

      {

   copy c(10);

    copy y(c);

    c.show( );

  y.show( );

  return 0;

}
