  1. saranjeet singh says:

    mdc project status : master array nd code length done…

  2. Nishant says:

    I have done master array, code length and conversion of integer to character. Now proceeding for data compression……

    • Nishant says:

      I have done 4-bit compression…………..

    • nishant says:

      while(*buff!=”)
      {
      for(i=0;i<strlen(mas_arr);i++)
      {
      if(*(mas_arr+i)==*(buff+j))
      {
      break;
      }
      }
      *(mas_arr+i)=*(buff+j);
      buff++;
      }

      After this the buff will show nothing in it or the size of buff is showing zero.What is the reason.

      while(*buff!=”)

      for(i=0;i<strlen(mas_arr);i++)
      {

      {
      break;
      }
      }
      *(mas_arr+i)=*buff;
      buff++;
      }

      After this the buff will show nothing in it or the size of buff is showing zero.What is the reason.

  3. started mdc project…..
    making master array…………

  4. vikas sharma says:

    i have done master ary and code length

  5. bhupendra.singh says:

    master array created progressing to code length development

  6. ravi.shankar says:

    i have done master array……..

  7. trilok.singh says:

    coding for master array and code length is done……

  8. chhavi garg says:

    done the master array and code length

  9. vaibhav chahal says:

    Made the master array and looking forward to the rest of the steps……

  10. RAHUL SRIVASTAVA says:

    while(*buff!=”)
    {

  11. while(*buff=”)
    {
    for(i=0;i<5;i++)
    {
    if(*(mastarray+i)==*buff)
    { goto here;
    }
    *(mastarray+i)=*buff
    }
    it is showing segmentation fault.

  12. Ankit Bhasin says:

    Done Master Array successfully,and now move to further steps..

  13. deepak kumar says:

    created master array….

    • deepak kumar says:

      if(*(ch+0)!=*(r+0))
      {
      *(r+0)=*(ch+0));
      }
      am getting d correct output only if d last charecter is same.if d same charecter is repeated after 2 or 3 charectr den again its typing d charecter bcoz d last charecter in d result had changed…

  14. shrey nagpal says:

    master array done
    proceeding further

  15. ashish sharma says:

    completed master array
    going further

  16. ravi soam says:

    completed master array successfully….
    doing code length coding….

  17. Abhishek Bist says:

    done till compression of 4 bits.

  18. deepak garg says:

    4-bit compression is done
    But I was confuse about my output for string given in class is

    { and its interger value is 123
    n ————————-110
    g————————–103
    w————————–119
    y————————–121

    Is this is write answer

  19. vikas says:

    90% of 4bit compression competed

  20. willy.jacob says:

    4-bit compression done..

    • willy.jacob says:

      getting an error when ndc greater than 8

      here is d code for compression
      for(i=0;i<ndc;i=i+2)
      {

      b=(char)i;
      c=(char)(i+1);
      b<<=4;
      c<>=4;
      *(res+k)=b|c;

      printf(“%d\t%p\n”,k,*(res+k));
      k++;
      }

  21. er.mohit says:

    done master array.working on code length.

  22. sunil110 says:

    i hv done 4bit and 2bit compression….

  23. willy.jacob says:

    getting an error when ndc is greater than 8

    here is d code for compression
    for(i=0;i<ndc;i=i+2)
    {

    b=(char)i;
    c=(char)(i+1);
    b<<=4;

    printf(“%d\t%p\n”,k,*(res+k));
    k++;
    }

  24. willy.jacob says:

    4 bit compression and decompression completed….

  25. shrey nagpal says:

    done 4 bit n 2 bit compression

  26. vaibhav chahal says:

    4bit n 2bit compression done

  27. pravin bhalerao says:

    I had completed 3 bit compression and now implementing decompression of it.

  28. pravin bhalerao says:

    i had also completed 4bit & 2bit compression/decompression.

  29. Pravin Bhalerao says:

    I had implemented 3bit decompression.

  30. Pravin Bhalerao says:

    I had done 2,3,4,5,6,7 bit com/decompression
    now i am trying to implement generlised code.
