Bit Stuffing Program

/* Write a program for Bit Stuffing*/

#include<stdio.h>

#include<conio.h>

#include<string.h>

void main()

{

int a[20],b[30],i,j,k,count,n;

clrscr();

printf("Enter frame length:");

scanf("%d",&n);

printf("Enter input frame (0's & 1's only):");

for(i=0;i<n;i++)

scanf("%d",&a[i]);

i=0; count=1; j=0;

while(i<n)

{

if(a[i]==1)

{

b[j]=a[i];

for(k=i+1;a[k]==1 && k<n && count<5;k++)

{

j++;

b[j]=a[k];

count++;

if(count==5)

{

j++;

b[j]=0;

 }

i=k;

}}

else

{

b[j]=a[i];

}

i++;

j++;

}

printf("After stuffing the frame is:");

for(i=0;i<j;i++)

printf("%d",b[i]);

getch();

}

OUTPUT:

Enter frame length: 10

Enter input frame (0's & 1's only):

1 0 1 0 1 1 1 1 1 1

After stuffing the frame is:

1 0 1 0 1 1 1 1 1 0 1
