C++ Program to Implement the Concept of Copy Constructor

COPY CONSTRUCTORS

AIM:

• To write the C++ program and to implement the concept of copy constructor

ALGORITHM:
1. Start the program
2. Include suitable header file
3. Declare constructor with empty arguments and another ,object as arguments
4. Initialize the value of a variable by calling a constructor in main function
5. Assign the value of one object to another object
6. Execute the program
7. Print the statement
8. Stop the program

CODING:
#include<iostream.h>
#include<conio.h>
class code
{
int id;
public:
code(){}
code(int a)
{
id=a;
}
code(code&x)
{
id=x.id;
}
void display(void)
{
cout<<id;
}
};
int main()
{
clrscr();
code a(100);
code b(a);
code c=a;
code d;
d=a;
cout<<"\nid of a:"; a.display();
cout<<"\nid of b:"; b.display();
cout<<"\nid of c:"; c.display();
cout<<"\nid of d:"; d.display();
getch();
return 0; }

OUTPUT:
id of A:100
id of B:100
id of C:100
id of D:100

RESULT:

• Thus to write the c++ program and implement the concept of copy constructor was successfully completed.
