    SUBEX  Placement Question Paper 2 2005

    Written test:one hour
    There are 2 parts.
    Part 1 : 20 C Qs (corect=+1, wrong= -1)
    Part 2 : 2 Programming problems, out of which you need to answer 1(have to write C
    code)


    Here are samples
    1.
    #include <stdio.h>
    int main()
    {
    char *str = "Hello, world" ;
    printf("%5s" , str);
    }
    Output :

    2.
    int *ptr[10];
    what is the above?
    a) declaration of 10 pointers
    b) declaration and defn of 10 pointers
    c) declaration and defn of an array of 10 pointers
    d) none

    3.
    #include <stdio.h>
    int main()
    {
    extern int i;
    printf("%d" , i);
    }
    a) garbage
    b) 0
    c) compiler error
    d) linker error

    4.
    #include <stdio.h>
    void temp();
    void temp(void);
    int main()
    {
    temp();
    }
    void temp()
    {
    printf("C is exciting!");
    }
    Output :

    5.
    #include <stdio.h>
    void temp(int i)
    {
    if(i == 10) return;
    i++ ;
    temp(i);
    printf("%d" , i);
    }
    int main()
    {
    temp(1);
    }
    Output :

    6.
    int func (int (*)(int) , int);
    int c
    ube(int n)
    {
    return (n*n*n);
    }
    int main()
    {
    prinf("%d" , func(cube , 4));
    }
    int func(int (*tmp)(int in) , int n)
    {
    int res , i;
    for(i = 1 ; i <= n ; i++)
    res += *(tmp)(i);
    return res;
    }
    Output :

    7.
    Some question on "strtok" function

    8.
    #include <stdio.h>
    int main()
    {
    char *str = "Hello, world";
    int i = sizeof(str);
    for( ; i >= 0 ; i--)
    printf("%c" , str[i]);
    }

    9.
    Some question on recursion

    10.
    #define MAX(A , B) ( A < B ? B : A )
    #include <stdio.h>
    int main()
    {
    int a = MAX( 4+2 , 3*2) ;
    printf(" %d " , a);
    }

    11.
    Question involving sizes of structure and unions


    Part 2 :
    1) program that recognizes date of any format
    even formats like "feb-2-2003" , "02-february-2003" , mm/dd/yy ,
    dd/mm/yy, etc and display it as mm/dd/yy

    2) a text filename is given as a command line argument followed by a
    character as the
    next argument. store all sentences NOT beginning with that
    character(ignore case)
    in a seperate file.
    NOTE THAT ITS SETENCES YOU'VE TO CONSIDER AND NOT LINES!!!!


    INTERVIEW


    There will be 3 rounds interviews,2 tech and 1 hr

    1st round


    1) full c and c++;
    2)something about project.
    (6 sem dbms and main);
    3)prog on linked list (reverse of singly link list)
    ie. u have contents like (eg:xebus) in l list how will u print
    it as subex
    ans(using stack or recursion);
    4)printf and scanf return values
    5)v.functs
    6)const funct(why)
    7)why static is defined outside the class


    2nd round


    1)single link list prog (using c++ insert front inser rear ins
    at position delete at position)
    base class contains 2 functs
    derived class 2 functions
    3)osi model; tcp/ip model
    4)vertual memory concepts;
    5)buble sort ,insert sort(with time complexity);
    6)ipc s in unix;


    3rd round


    It is taken by COO of Subex and will be Tech cum HR.
    They also try to give u some stress so be prepared.
