1. if a 5-stage pipe-line is flushed and then we have to execute 5 and
       12instructions respectively then no. of  cycles will be
    a. 5 and 12
    b. 6 and 13
    c. 9 and 16
    d. none

    2. k-map

    ab
    ----------
    c       1   x  0  0
           1   x  0  x

    solve it

    a. A.B
    B. ~A
    C. ~B
    D. A+B

    3.CHAR  A[10][15] AND INT B[10][15] IS DEFINED
    WHAT'S THE ADDRESS OF A[3][4] AND B[3][4]
    IF ADDRESS OD A IS OX1000 AND B IS 0X2000

    A. 0X1030 AND 0X20C3
    B. OX1031 AND OX20C4
    AND SOME OTHERS..

    4. int f(int *a)
    {
    int b=5;
    a=&b;
    }

    main()
    {
    int i;
    printf("\n %d",i);
    f(&i);
    printf("\n %d",i);
    }

    what's the output .

    1.10,5
    2,10,10
    c.5,5
    d. none

    5. main()
    {
    int i;
    fork();
    fork();
    fork();
    printf("----");
    }

    how many times the printf will be executed .
    a.3
    b. 6
    c.5
    d. 8

    6.
    void f(int i)
    {
    int j;
    for (j=0;j<16;j++)
    {
    if (i & (0x8000>>j))
    printf("1");
    else
    printf("0");
    }
    }
    what's the purpose of the program

    a. its output is hex representation of i
    b. bcd
    c. binary
    d. decimal

    7.#define f(a,b) a+b
    #define g(a,b) a*b

    main()
    {

    int m;
    m=2*f(3,g(4,5));
    printf("\n m is %d",m);
    }

    what's the value of m
    a.70
    b.50
    c.26
    d. 69

    8.
    main()
    {
    char a[10];
    strcpy(a,"\0");
    if (a==NULL)
    printf("\a is null");
    else
    printf("\n a is not null");}

    what happens with it .
    a. compile time error.
    b. run-time error.
    c. a is  null
    d. a is not  null.

    9. char a[5]="hello"

    a. in array we can't do the operation .
    b. size of a is too large
    c. size of a is too small
    d. nothing wrong with it .

    10. local variables can be store by compiler
    a. in register or heap
    b. in register or stack
    c .in stack or heap .
    d. global memory.

    11. average and worst time complexity in a sorted binary tree is

    12. a tree is given and ask to find its meaning (parse-tree)
    (expression tree)
    ans. ((a+b)-(c*d))  ( not confirmed)
    13. convert 40.xxxx into binary .

    14. global variable conflicts due to multiple file occurance
    is resolved during
    a. compile-time
    b. run-time
    c. link-time
    d. load-time

    15.
    two program is given of factorial.
    one  with  recursion and one without recursion .
    question was which program won't run for very big no. input     because
of stack overfow .
    a. i only  (ans.)
    b. ii only
    c. i& ii both .
    c. none

    16.
    struct a
    {
    int a;
    char b;
    int c;
    }

    union b
    {
    char a;
    int b;
    int c;
    };
    which is correct .
    a. size of a is always diff. form size of b. (ans.)
    b. size of a is always same  form size of b.
    c. we can't say anything because of not-homogeneous (not in ordered)
    d. size of a can be same if ...
