Q 1 © Will the following program execute
successfully? If not, state the reason(s).

{
if(x%y==0) return ++x; else return y–;
} void main()

Q 2©Consider the following and answer the following
questions given below:
class School
{
int A;
protected:
int B,C;
public:
void INPUT(int);
void OUTPUT( );
} ;
class Dept:protected School
{
int X,Y;
protected:
void IN(int, int);
public:
void OUT( );
};
class Teacher:public Dept
{
int P;
void DISPLAY(void);
public:
void ENTER( );
};
(i)Name the base class and derived class of the class Dept.
(ii) Name the data member(s) that can be accessed from function OUT( ).
(iii) Name the private member function(s) of class Teacher.
(iv) Is the member function OUT( ) accessible by the objects of Dept?
Q 3. (a)Suppose A, B, C are arrays of integers of size M, N
and M+N respectively. The members in array A appear in ascending order
while the members in array B appear in descending order. Write a user
defined function in C++ to produce third array C by merging arrays A and B
in ascending order. Use A, B and C as arguments in the function.
Q 3 (b) An array VAL[1……15][1……10] is stored in the
memory with each element requiring 4 bytes of storage. If the base address
of array VAL is 1500, determine the location of VAL[12][9] when the array
VAL is stored (i) Row wise (ii) Column wise.
Q 3 © Write a user-defined function in C++ to find and
display the sum of both the diagonal elements of a two dimensional array
MATRIX[6][6] containing integers.
Q 3 (d) Evaluate the following postfix expression using a
stack. Show the contents of stack after execution of each operation:
20, 8, 4, /, 2, 3, +, *, -
(e) Give necessary declaration for a queue containing float type numbers;
also write a user defined function in C++ to insert a float type number in
the queue. You should use linked representation of queue.
Q 4 (a)Name two member functions of ofstream class.
Q 4 (b) Assuming the class DRINKS defined below, write
functions in C++ to perform the following:
(i)Write the objects of DRINKS to a binary file.
(ii) Read the objects of DRINKS from binary file and display them on
screen when DNAME has value “INDY COLA".
class DRINKS
{
int DCODE;
char DNAME[13]; //Name of the drink
int DSIZE; //Size in liters float DPRICE;public:
void getdrinks( ) {cin>>DCODE>>DNAME>>DSIZE>>DPRICE;}
void showdrinks( )
{cout<
char *getname( ){return DNAME;} };
Q 5. (a) What is the need for normalistion? Define third
normal form.
Write SQL commands for (b) to (e) and write the outputs for
(g) on the basis of table CLUB.
