 1. (a) What is the difference between Object Oriented Programming and Procedural Programming? 

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

(i) frexp() (ii) isalnum()

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

       #include <iostream.h>

         struct Pixels

        { int Color,Style;}

        void ShowPoint(Pixels P)

         { cout<<P.Color,P.Style<<endl;}

            void main()

       {

              Pixels Point1=(5,3);

              ShowPoint(Point1);

              Pixels Point2=Point1;

             Color.Point1+=2;

              ShowPoint(Point2);

          }

(d) Find the output of the following program: 

     #include <iostream.h>

     void Changethecontent(int Arr[], int Count)

       {

            for (int C=1;C<Count;C++)

            Arr[C-1]+=Arr[C];

       }

            void main()

          {

                int A[]={3,4,5},B[]={10,20,30,40},C[]={900,1200};

                Changethecontent(A,3);

                Changethecontent(B,4);

                Changethecontent(C,2);

                 for (int L=0;L<3;L++) cout<<A[L]<<’#’;

                cout<<endl;

                 for (L=0;L<4;L++) cout<<B[L] <<’#’;

                 cout<<endl;

                 for (L=0;L<2;L++) cout<<C[L] <<’#’;

            }

2. (a) Write a function in C++ to combine the contents of two equi-sized arrays A and B by computing their corresponding elements with the formula 2*A[i]+3*B[i]; where value i varies from 0 to N-1 and transfer the resultant content in the third same sized array. 

(b) An array P[20][30] is stored in the memory along the column with each of the element occupying 4 bytes, find out the memory location for the element P[5][15], if an element P[2][20] is stored at the memory location 5000. 

(c) Write a function in C++ to perform Push operation on a dynamically allocated Stack containing real numbers. 

(d) Write a function in C++ to find sum of rows from a two dimensional array. 

(e) Evaluate the following postfix notation of expression:  True, False, AND, True, True, NOT, OR, AND
