3. Do you play football or basketball?
4. Suppose there are 64 cricket teams and there is knock out match. So how many matches they need to play to decide the final winner?
5. What strategy did you apply?
6. Can you write a C function for this? (as I mentioned my area of interest is C)
7. Today is 26 August, Tuesday. What was the day 4 months ago? Tell me only the strategy and also   write C function for this.
8. Suppose a program is given, which language you will prefer between C and C# and why?    (I mentioned both languages in my CV)
9. Can a Statistical model be developed by C?
10. Why should we hire you?
11. I am done from my  side, if you have any question you can ask.

Suggestions: - Here are some suggestions what I experienced-
1. They are mainly focus on your logical thinking to solve problems. That’s why they are asking 1 or 2 puzzles to everyone. So focus on solving the puzzles.
2. They are also asking question from your area of interest as you said during your interview. So be careful what you    are going to mentioned and make sure you are strong enough.
3. They also asked about the final year M.Tech project. So have some idea what is your project is all about and how will you go further in your project.

cavium networks sample question

Q1) 

Define the enum ABC having attributes POSITIVE, NEGATIVE, and ZERO such that the 'fun()' function prints Postive for a positive number, Negative for a negative number and Zero for 0.

#include<stdio.h>

enum ABC

{

__________      //First Line

__________      //Second Line

__________      //Third Line

};

void fun(int num)

{

      if(num<=NEGATIVE)

           printf("Its a negative number\n");

      else

      {

           if(num>=POSITIVE)

                  printf("Its a positive number\n");

           else

                  printf("Zero\n");

      }

}

int main()

{

     int i;

     scanf("%d",&i);

     fun(i);

     return 0;

}

Answer: 

(a)

enum{

ZERO;

POSITIVE;

NEGATIVE=-1;

};

(b)

enum{

POSITIVE=1;

ZERO=0;

NEGATIVE=-1;

};

Q2)

#define Y 10

#define X 1-(Y)

int main()

{

    int val;

    val=200*X

    printf("Value of val is %d\n",val);

    return 0;

}

Answer: 190

Q3)

struct ABC

{

      int a;

      char b;

      void *c;

};

int main()

{

     struct ABC *obj=NULL;

     printf("%d: %d: %d: %d: %d\n",sizeof(obj->a),sizeof(obj->b),sizeof(obj->c),sizeof(obj),sizeof(struct ABC));

     return 0;

}

Answer:

4: 1: 4: 4: 12

Q4)

Design a data structure which can add 2 numbers in the range of 2127 to 2127-1

Answer:

struct my128int

{

     int a[4];

};

Q5) Using the data structure define above write a program which can add two numbers.

Q6) Using System Calls define printf function. Assume only one argument can be passed to this function.

Q7) Suppose you are having an instruction

sbn A,B,C

defined as

Memory[A]=Memory[A]-Memory[B]

if(Memory[A]<0)

    ProgramCounter=C.

Now, you are asked to write a code for moving the content of X to Y.

Answer:

sbn Y,Y,C     // setting Y=0

sbn T,T,C      // T is a temporary variable

sbn T,X,ProgramCounter+4      // T=-X

sbn T,X,ProgramCounter+4      // T=-2X

sbn Y,X,ProgramCounter+4      //  Y=-X

sbn Y,T,C                                  //  Y=X

sbn X,X,C                                  //  X=0

Q8)

#include<stdlib.h>

#include<stdio.h>

int main()

{

     int *p,*q,*r;

     p=malloc(sizeof(int));

     free(p);

     q=malloc(sizeof(int));

     free(q);

     r=malloc(sizeof(int));

     return 0;

}

Does p,q and r point to the same location?

Answer: Yes

Q9)

void fun(x)

{

    lock();

    IO_intensive();

    CPU_Intensive();

    unlock();

}

int main()

{

    fun(a);

    fun(b);

    fun(c);

    fun(d);

}

Choose the best answer:

(a) Uniporcessor System will give optimal performance for this situation.

(b) Dual Core will give optimal performance for this situation.

(c) Quad Core will give optimal performance for this situation.

(d) Multicore with altered code will give optimal performance for this situation..

Q10)

typedef struct tree* NODE

struct tree

{

    int info;

    struct tree *leftMostSibling,*rightSibling;

};

int fun(NODE root)

{

    int value=0;

    if(root)

    {

        value=1;

        value=value+fun(root->leftMostSibling);

        value=value+fun(root->rightSibling);

    }

    return(value);

}

What does function 'fun' returns?

Answer: Numbers of node in a tree.

Q11)

What is the output of the program given below?

#include<stdio.h>

void fun(int *p)

{

     p=malloc(sizeof(int));

}

int main()

{

     int *p=NULL;

     fun(p);

     if(p)

         printf("p is not null");

     else

         printf("null");

    return 0;

}

Answer: null

Q12)

int main()

{

    int a=0xabcdef;

    char *p;

    p=&a;

    printf("%x\n",*p);

    return 0;

}

What is the output?

Answer: Using the concept of big endian and little endian. It will be either '00' or 'ef'

Basic needs to get placement

Hi guys, the main things that every company is concentrating while they are coming for campus drive are
For Dream companies:

• C programming in detail    book to follow
• Data structures                   book to follow
• Operating Systems             videos   &  pdfs 

For Non-Dream companies:

• Arithmetic                          R.S agarwal books highly enough
• Reasoning                          R.S agarwal books highly enough
• English                               R.S agarwal books highly enough
• C programming                  The C Programming Language (Ansi C Version)  dennis ritchie c
• Little bit OS concepts        

for OS, CN gate material is also highly enough..
these  are  only a suggestion you can choose your own book to follw.
