C/C++ Source Codes

a programme for starting knowledge about The COPY CONSTRUCTOR

#include<iostream.h>
#include <string.h>
class person
{
public:
char *name;
int age;
person (char *n = "no name", int a = 0)
{
name = new char[100];
strcpy (name, n);
age = a;
}
person (person &s) // The COPY CONSTRUCTOR
{
strcpy (name, s.name);
age = s.age;
}
~person ()
{
delete (name);
}
};

void main ()
{
person p;
cout << p.name << ", age " << p.age << endl << endl;
person k ("John", 56);
cout << k.name << ", age " << k.age << endl << endl;
p = k;
cout << p.name << ", age " << p.age << endl << endl;
p = person ("Bob", 10);
cout << p.name << ", age " << p.age << endl << endl;
}
