Parameterized Constructor (Overloaded Constructor):- Parameterized constructor accepts parameters and is
used to assign these parameters to the data members of the class. There may be many definitions of the
parameterized constructor depending upon the type and number of parameters passed to the constructor and
so it is also called overloaded constructor.

For example.

#include<iostream.h>
class student
{
int rollno;
float percentage;
public:
student() // default constructor
{
rollno=0;
percentage=0.0;
}
student(int rno,float p) //parameterized constructor
{
rollno=rno;
percentage=p;
}
void display()
{
cout<<"RNo. "<<rollno;
cout<<"\n per "<<percentage;
}
};
void main()
{
student s; //call for the default constructor
student s1(5,88.5); //call for the parametrized constructor
s.display();
s1.display();
}
(c) Define a class RESORT in C++ with following description: (4)

Private Members:

Rno // Data member to store Room No

Name // Data member to store customer name

Charges // Data member to store per day charges

Days // Data member to store number of days of stay

COMPUTE( ) // A function to calculate and return Amount as Days* Charges and if the value of Days *
