I know goto's are evil, but I tend to write such as:

int i;
for (i=0; i<10; i++)
{
   Lretry:
     if (string.substr(i,1) == something)
     {
         i += some_other_function();
         goto Lretry;
     }
     else if (string.substr(i,1) == something_else)
     {
         i += some_other_function2();
         goto Lretry;
     }
     // Otherwise, simply execute the "i++" and re-test
}
