CONSTRUCTORS
CONSTRUCTORS :
A member function with the same as its class is called Constructor and it is used to initialize the object of that class with a legal initial value.
Example :
class Student
{
int rollno;
float marks;
public:
student( ) //Constructor
{
rollno=0;
marks=0.0;
}
//other public members
};
TYPES OF CONSRUCTORS:
1. Default Constructor: A constructor that accepts no parameter is called the Default Constructor. If you don't declare a constructor or a destructor, the compiler makes one for you. The default constructor and destructor take no arguments and do nothing.
2. Parameterized Constructors: A constructor that accepts parameters for its invocation is known as parameterized Constructors , also called as Regular Constructors.
Copy Constructor
• A copy constructor is a special constructor in the C++ programming language used to create a new object as a copy of an existing object.
• A copy constructor is a constructor of the form classname(classname &).The compiler will use the copy constructors whenever you initialize an instance using values of another instance of the same type.
• Copying of objects is achieved by the use of a copy constructor and a assignment operator.
Example :
class Sample{ int i, j;}
public:
Sample(int a, int b) // constructor
{ i=a;j=b;}
Sample (Sample & s) //copy constructor
{ j=s.j ; i=s.j;
Cout <<”\n Copy constructor working \n”;
}
void print (void)
{cout <<i<< j<< ”\n”;}
:
