CBSE CLASS XII

Computer Science (C++ and Data Structure)

50. Define a class Taxpayer, whose class description is given below:- 
    Private Members:-
    int pan - to store the personal account no.
    char name[20] - to store the name
    float taxableinc - to store the total annual taxable income.
    float tax - to store the tax that is calculated.
    computetax ( )- A function to compute tax from the following rule:-
    

    Total Annual Taxable Income	Rate of Taxation
    Up to 60000	0%
    Greater than 60000, less than = 150000	5%
    Above 150000, upto 500000	10%
    Above 500000	15%

    Public Members :-
    inputdata ( ) - A function to enter the data and call the compute tax( ) function.
    display( ) - To display the data.

    1. Write the names of data members which are accessible from objects belonging to class cloth.
    2. Write the names of all members which are accessible from objects belonging to class design.
    3. Write the names of all the data members which are accessible from member functions of class costing.
    4. How many bytes will be required by an object belonging to class design?
51. Write a function in C++ which accepts an integer array and its size as arguments / parameters and arrange all the odd numbers in the first row and even numbers in the second row of a two dimensional array as follows. The unused cells of two dimensional array must be filled with 0.
    If the array is   1, 2, 3, 4, 5, 6 
    The resultant 2-D array is given below           
    1          3          5          0          0          0 
    0    0    0          6          4          2
52. A 2-d array defined as A[4..7, -1..3] requires 2 words of storage space for each element stored in  row major order. Calculate the address of A[7,0] and base address if the location of A[6,2]  as 126.
53. Consider the following portion of a program, which is implemented as linked list of library. Write the definition of function PUSH( ), to insert a new node in the stack and definitions of function POP(), to delete a node from the stack
    struct Library
    {
    int id;
    char name[20];
    Library *Link;
    };
54. What is the purpose of seekp() and seekg( )
55. Write a function in C++ to read a text file “SPACE.TXT” . Using this file create another file “ OUT.TXT”  by  replacing more than one space by single space.
    Example:
    If the file “SPACE .TXT” contains the  following
    I like ice cream.

    The function should create another file OUT.TXT with the text
     I like ice cream.

56. Write a function in C++ to transfer a particular type of stock from the file “inventory.dat” to another file “backinvent.dat”. Assuming that the binary file is containing the records of following structure :
    struct Products
    {
    int id;
    char Iname[30];
    int type;
    };
    Remember that transfer means deletion from the “inventory.dat” file and addition in the “backinvent.dat” file.
