   I use unsigned integers if negative values are not involved, where the   
   extra positive values might be useful. Here’s an example of the kind   
   of loop I might write:   
      
       unsigned int i;   
       bool found;   
       for (i = len(s);;)   
         {   
           if (i == 0)   
             {   
               found = false;   
               break;   
             } /*if*/   
           if (matches(s[i]))   
             {   
               found = true;   
               break;   
             } /*if*/   
           --i;   
         } /*for*/
