 1. (a) Differentiate between a Run Time Error and Syntax Error. Also give suitable examples of each in C++. 

    (b) Name the header file(s) that shall be needed for successful compilation of the following C++ code 1

         void main ( )

          {

             char String [20];

             gets (String);

             strcat (String, “CBSE”);

             puts (String);

           }

(c) Differentiate between Constructor and Destructor function in context of Classes and Objects using C++

2. (a) Write a function in C++ which accepts an integer array and its size as arguments and replaces elements having odd values with thrice its value and elements having even values with twice its value.

          Example : if an array of five elements initially contains the elements as

                          3, 4, 5, 16, 9

            then the function should rearrange the content of the array as

                            9, 8, 15, 32, 27 4

(b) An array Array[20][15] is stored in the memory along the column with each element occupying 8 bytes. Find out the Base Address and address of the element Array[2][3] if the element Array [4] [5] is stored at the address 1000. 

(c) Write a function in C++ to delete a node containing Book’s information, from a dynamically allocated Stack of Books implemented with the help of the following structure. 

            struct Book

              }

            int BNo;

            char BName[20];

            Book *Next;

              };

(d) Write a function in C++ which accepts a 2D array of integers and its size as arguments and displays the elements which lie on diagonals. 2 [Assuming the 2D Array to be a square matrix with odd dimension i.e. 3×3, 5×5, 7×7 etc.]

Example, if the array content is

5 4 3

6 7 8

1 2 9

Output through the function should be :

Diagonal One : 5 7 9

Diagonal Two : 3 7 1

(e) Evaluate the following postfix notation of expression : 

25 8 3 - / 6 * 10 +

3. (a) What is the significance of Cyber law ? 

    (b) Expand the following terms with respect to Networking : 

          (i) CDMA (iii) FTP

          (ii) WLL (iv) HTML

     (c) Which of the following unit measures the speed with which data can be transmitted from one node to another node of a network? Also, give the expansion of the suggested unit. 

         (i) Mbps

         (ii) KMph

         (iii) MGps

(d) Differentiate between primary key and alternate key.
