I think this should work....tell me if this works...
void longest_0_1_substring(char *str)
{
int size=0,count=0,max=0,pos=0,prev=0,prev_pos=0,ptr=0,i=0,j=0;
while(*str++)
size++;
str -= (size + 1);
while(i<size)
{
for(j=i;(j < size) && (str[j]==str[j+1]);++j)
count++;
count++;
if(ptr > 1)
{
if(count >= prev)
{
if(prev > max)
{
max = prev;
pos = prev_pos;
}
}
else
{
if(count > max)
{
max = count;
pos = i - prev;
}
}
}
prev = count;
prev_pos = i;
i += count;
++ptr;
count = 0;
}
printf("substring starts at position %d and is of size %d .",pos,max);
}
