Program for bit stuffing...?

Answer 1

Answer: Program for bit stuffing in C

#include<stdio.h>

      int main()

    {    

          int i=0,count=0;

          char data[50];

          printf("Enter the Bits: ");

          scanf("%s",data);            //entering the bits ie. 0,1  

          printf("Data Bits Before Bit Stuffing:%s",databits);

          printf("\nData Bits After Bit stuffing :");

          for(i=0; i<strlen(data); i++)

              {

              if(data[i]=='1')

                     count++;

              else

                     count=0;

                printf("%c",data[i]);

             if(count==4)

                {

                          printf("0");

                          count=0;

                 }

             }

    return 0;

 }

Explanation:

bit stuffing is the insertion of non-information bits during transmission of frames between sender and receiver. In the above program we are stuffing 0 bit after 4 consecutive 1's. So to count the number of 1's we have used a count variable. We have used a char array to store the data bits . We use a for loop to iterate through the data bits to stuff a 0 after 4 consecutive 1's.
