1. (a) What is the difference between Global Variable and Local Variable? 

(b) Write the names of the header files to which the following belong: 

(i) strcmp() (ii) fabs()

(c) Rewrite the following program after removing the syntactical errors (if any). Underline each correction. 

     #include [iostream.h]

    class PAYITNOW

     {

       int Charge;

       PUBLIC:

       void Raise(){cin>>Charge;}

       void Show{cout<<Charge;}

      };

          void main()

         {

             PAYITNOW P;

             P.Raise();

              Show();

          }

(d) Find the output of the following program: 

         #include <iostream.h>

        struct PLAY

          { int Score, Bonus;};

             void Calculate(PLAY &P, int N=10)

          {

               P.Score++;P.Bonus+=N;

           }

               void main()

             {

                   PLAY PL={10,15};

                   Calculate(PL,5);

                   cout<<PL.Score<<”:”<<PL.Bonus<<endl;

                   Calculate(PL);

                   cout<<PL.Score<<”:”<<PL.Bonus<<endl;

                   Calculate(PL,15);

                   cout<<PL.Score<<”:”<<PL.Bonus<<endl;

              }

2.(a) Write a function in C++ to merge the contents of two sorted arrays A & B into third array C. Assuming array A is sorted in ascending order, B is sorted in descending order, the resultant array is required to be in ascending order.

(b) An array S[40][30] is stored in the memory along the row with each of the element occupying 2 bytes, find out the memory location for the element S[20][10], if an element S[15][5] is stored at the memory location 5500. 

(c) Write a function in C++ to perform Insert operation in a dynamically allocated Queue containing names of students. 

(d) Write a function in C++ to find the sum of both left and right diagonal elements from a two dimensional array (matrix). 

(e) Evaluate the following postfix notation of expression:  20,30,+,50,40,-,*
