1 a. What do you understand about a member function? How does a member function differ from an ordinary function. Explain with example ?
1 b. Define a class Student for the following specifications.
Private members of the Student are:
roll_no integer
name array of characters of size 20
class_st array of characters of size 8
marks array of integers of size 5,
Percentage float
Calculate( ) that calculates overall percentage marks and returns the percentage
Public Members of the Student are:
Readmarks reads mark and invoke thecalculate function
Displaymarks prints the data.
2.a) Differentiate between Constructor and Destructor function in context of Classes
and Objects Using C++? Explain with example
2.b) Answer the questions (i) and (ii) after going through the following program:
#include <iostream.h>
#include<string.h>
class bazaar
{ char Type[20] ;
char product [20];
int qty ;
float price ;
bazaar() //function 1
{ strcpy (type , “Electronic”) ;
strcpy (product , “calculator”);
qty=10;
price=225;
}
public :
void Disp() //function 2
{ cout<< type <<”-”<<product<<”:” <<qty<< “@” << price << endl ;
}
};
void main ()
{ Bazaar B ; //statement 1
B. disp() ; //statement 2
}
(i) Will statement 1 initialize all the data members for object B with the values given in the function 1 ? (YES OR NO). Justify your answer suggesting thecorrection(s) to be made in the above code.
(ii) What shall be the possible output when the program gets executed ? (Assuming, if required _ the suggested correction(s) are made in the program).
2.c) Define a class Tour in C++ with the description given below.
Private Members:
TCode of type string
No of Adults of type integer
No of Kids of type integer
Kilometers of type integer
TotalFare of type float
Public Members:
• A constructor to assign initial values as follows:
TCode with the word “NULL”
No of Adults as 0
No of Kids as 0
Kilometers as 0
TotalFare as 0
• A function AssignFare() whichcalculates and assigns the value of the data member Totalfare as follows For each Adult
Fare(Rs) For Kilometers
500 >=1000
300 <1000 & >=500
200 <500
For each Kid the above Fare will be 50% of the Fare mentioned in the above table
For Example: If Kilometers is 850, Noofadults =2 and NoofKids =3 Then TotalFare should be calculated as Numof Adults *300+ NoofKids *150 i.e., 2*300+ 3 *150 =1050
• A function EnterTour() to input the values of the data members TCode, NoofAdults, NoofKids and Kilometers ; and invoke the AssignFare() function.
• A function ShowTour() which displays the content of all the data members for a Tour.
