C program to Implement Character Count in Data Link Layer

#include<stdio.h>
#include<conio.h>
#include<string.h>
void main()
{
int x[20],y[30],i,j,k,count,n;
printf("Enter the frame length: ");
scanf("%d",&n);
printf("Enter the input frame (0's & 1's only): ");
for(i=0;i<n;i++)
scanf("%d",&x[i]);
i=0; count=1; j=0;
while(i<n)
{
if(x[i]==1)
{
y[j]=x[i];
for(k=i+1;x[k]==1 && k {
j++;
y[j]=x[k];
count++;
if(count==5)
{
j++;
y[j]=0;
}
i=k;
}}
else

}
i++;
j++;
}
printf("After stuffing the frame is: ");
