Finding consecutive bit string of 1 or 0

Question

How to find the length of the longest consecutive bit string(either 1 or 0)?

00000000 11110000 00000000 00000000 -> If it is 0 then length will be 20

11111

Answer 1

Since you didn't wrote what is bit string (regular int, byte array or char string I've assumed that it's char array

int maxConsBits(char *pStr,char cChar)
{
    char curChar;
    int curMax = 0;
    int max = 0;
    while (pStr)
    {
       if (*pStr == cChar)
       {
          curMax++;
          if (curMax > max)
          {
             max = curMax;
          }
       }
       else
       {        
           curMax = 0;
       }
       pStr++;
   }
   return max;
}
