     QUARK  Placement Sample Question Paper 

    There was an online written test

    50 questions = 10 comp. awareness, 10 mathematical (easy), 10 verbal reasoning(difficult, lenghty, you are advised to attempt them at last only ), 20 c++ or c or Java  whichever u opt.
    then three interviews, (2 technical, one hr) are taken.
    quarks people stress on c++, os, dbms, SE(testing, sdlc etc.) in the interview.

    here are some questions that i can recall from the written test.

    one question of c++

    main()
    {
    int x=10,y=20,z=5;
    x=x cout < }
    ans 1


    here quarks was on 12-8-03 and
    recruit 2 mca's and 12
    be's.

    first you should opt test in c++,
    because they have
    only requirements in c++.
    they will ask questions on virtual
    functions,
    destructures etc.

    there are 50 questions and time is
    60 mins.
    1-10 analytical reasoning
    11-20 quant
    21-30 computer awearness
    31-50 c++

    c & c++ questions are diffirent in
    quant and in comp
    awearness.
    the analytical reasoning will take
    time so u should do
    this at last i.e. by seeing the
    length of question.

    quant was easy

    1. 165^2-164^2
    a 329 ans
    b 325

    2. there is one question onloan
    from father of 240
    rupees the answer of that question
    is 21.

    1. can there be a static class


    2. dynamic binding is
    options


    3 o/p of following prog

    main()
    {
    int i,j=9999;
    char buff[5];
    i=sprintf(buff,"%d",j);

    cout< }

    a. 9999, 4
    b 9999,5 ans
    c 4,9999
    d 9999,1



    4. class ab{};
    main()
    {
    cout< }

    a 1
    b 0 ans
    c 2
    d 4


    5.

    class ab
    {
    int i;
    public:
    virtual void fun(){}
    }
    main()
    {
    cout< }

    a. 4 ans




    6. when new fails it
    a. send _set_new_handler
    b. send excection
    c.
    d. both a and b



    7. #define f(a,b) a+b
    #define g(x,y) x*y
    main()
    {
    int i;
    i=f(4,g(5,6));
    cout< }

    a. 34 ans


    8 #define x(a) ++a + a++ +a++
    like this I do not
    remember this question ans was 4.

    {
    cout<<?Quark?;
    }
    else
    {
    cout<<?express?;
    }
    Ans. express

    Q8. int func(int I)
    {

    {
    cout << func(1);
    }

    Ans. 1



    Q9. class base
    {
    public:
    virtual func()
    {
    cout <<?BASE?;
    }
