Slip 16 - A) Write a C++ program to create a class Machine with data members Machine_Id, Machine_Name,Price. Create and initialize all values of Machine object by using parameterized constructor and copy constructor. Display details of Machine using setw() and setprecision( ).

 Solution:

#include<iostream.h>

#include<conio.h>

#include<iomanip.h>

#include<string.h>

class Machine

{

private:

int Machine_Id, Price;   //data members

char name[10];

public:

Machine(int x1, int y1,char *z1)

{

strcpy(name,z1);

Machine_Id = x1;

Price = y1;

 }

 /* Copy constructor */

Machine (const Machine &sam)

{

strcpy(name,sam.name);

Machine_Id=sam.Machine_Id;

Price=sam.Price;

 }

 void display()

{

cout<<"\n Name:\t"<<name;

cout<<"\n MachineID:\t"<<setprecision(2)<<Machine_Id;

cout<<"\n Price:\t"<<setw(3)<<Price;

 }

};

/* main function */

int main()

{

Machine obj1(123, 1534,"archana");     // Normal constructor

Machine obj2 = obj1;      // Copy constructor

cout<<"Normal constructor : ";

obj1.display();

cout<<"Copy constructor : ";

obj2.display();

return 0;

}
