Price, TotalPrice, Discount, Netprice float
Member Functions: Public members:
• A constructer to assign initial values of Customer_no as 111, Customer_name as
“N.A.”, Quantity as 0 and Price, TotalPrice, Discount and Netprice as 0.
• Input( ) – to read data members(Customer_no, Customer_name, Quantity and Price)
and invoke Caldiscount().
• Caldiscount ( ) – To calculate TotalPrice, Discount and NetPrice
Where : TotalPrice = Price*Qty
TotalPrice >=50000 : Discount 25% of TotalPrice
TotalPrice >=25000 and <50000 : Discount 15% of TotalPrice
TotalPrice <250000 : Discount 10% of TotalPrice
Netprice= TotalPrice-Discount
• Show( ) – to display Customer details.

d. Give the following class definition answer the question that is follow: 4

class University class College : class Department :
{ private University protected College
char name [20]; { int regno; char name[20];
protected : protected: char HOD[20];
char vc[20]; char principal[25]; public :
public : public : void fetchdata(int);
void estd(); long no_of_students; void displaydata( );
void inputdata(); void readdata(); };
void outputdata(); void dispdata ( );
} ; };
i. Name the base class and derived class of college.
ii. What will be the size of an object (in bytes) of class Department? What type of
inheritance is depicted in the above class definition?
iii. Name the private data members of class College.
iv. Name the members accessible from objects of class Department.

3 a. Write a function int SUM_ALL (int ARR [ ], int size) that returns the sum of all even 2
elements of the array that are not between 101 and 200.

b. Write a function REV_COL (int A [ ][ ], int r, int c) that accepts a two digit array and 3
reverses the contents of all columns. For eg:
Original Array: Array after Reversed Columns:
64 52 5 81 74 16 42 14
32 18 29 72 56 34 7 90
56 34 7 90 32 18 29 72
74 16 42 14 64 52 5 81

c. Given an array A[10][12] whose base address is 10000. Calculate the memory location 3
of A[2][5] if each element occupies 4 bytes and array is stored
i. Column wise.
ii. Row wise

d. Evaluate the following postfix expression: (show status of Stack after each operation) 2
i) 6, 40, 8,/,20,10,–,+,*
ii) True, False, True, NOT, True, OR, AND, AND

e Define member function delque( ) to perform delete operation on a linked queue where 2
