Ans (i) class City
(1 mark for correct answer)

(ii) None
(1 mark for correct answer)

(iii) Data members: Country_Id, Country_Name[25], State_Population,

City_Population

Get_Population(), New_City(), Show_City()
(1 mark for correct answer)

(iv) 90 bytes for object of class Country & 63 bytes for object of class State
(1/2 mark for each correct answer)

Q3 (a) Write the definition of function named Array_Swap() that will accept an integer array & 3

its size as arguments and the function will interchange/swap elements in such a way that
the first element is swapped with the last element, second element is swapped with the

second last element and so on, only if anyone or both the elements are odd.

E.g. if initially array of seven elements is:
5, 16, 4, 7, 19, 8, 2

After execution of the above function, the contents of the array will be:
2,16, 19, 7, 4, 8, 5

Ans

(½ Mark for correct function header)

(½ Mark for correct loop)
(1 Mark for correct checking of odd elements in each pair)

(1 Mark for swapping the elements)

(b) An array A[50][30] is stored along the row in the memory with each element requiring 4 3
bytes of storage. If the element A[10][15] is stored at 21500, then find out the base
