Member Functions
• A constructor function to initialize Type as ‘O’ and Fare(Freight) as 500
• A function to calculate Fare as per the following criteria:

Type Fare
‘O’ 15 * Distance
‘E’ 20 * Distance
‘L’ 24 * Distance
• A function Allocate( ) to allow user to enter values for Busno, From, To, Type and Distance. Also this
function should call CalcFare( ) to calculate Fare.
• A function Show( ) to display the content of all the data members on screen. [4]

(d) Consider the following C++ code and answer the questions from (i) to (iv): [4]
class Personal
{
int Class, Rno;
char * Section;
protected :
char * Name;
public :
personal( );
void pentry( );
void Pdisplay( );
};
class Marks : private Personal
{
float M[5];
protected :
char Grade[5];
public :
Marks( );
void Mentry( );
void Mdisplay( );
};
class Result : public Marks
{
float Total, Agg;
public :
char FinalGrade, comments[20];
Result( );
void Rcalculate( );
void Rdisplay( );
};
(i) Which type of inheritance is shown in the above example?
(ii) Write the names of those data members, which can be directly accessed from the objects of class Result.
(iii) Write the names of those member functions which can be directly accessed from the objects of class Result.
(iv) Write the names of those data members, which can be directly accessed from the Mentry( ) function of
class Marks.

Q.3(a)Write a finction TRANSFER(int A[ ] , int B[ ] , int size) in C++ to copy the elements of array A into array B in such a
way that all the negative elements of A appear in the beginning of B , followed by all the positive elements , followed by
all the zeroes maintaining their respective orders in array A . For example :
If the contents of array A are :- 7 , -23 , 3 , 0 , -8 , -3 , 4 , 0
The contents of array B should be -23 , -8 , -3 , 7 , 3 , 4 , 0 , 0 [3]
(b) Each element of the array A[8][6] is stored along the column using 4 bytes of memory . If the element A[2][4] is stored
at location 936 , find the address of A[5][1] . [3]
