(1) findMax.cc: finding the maximum value in an array

(2) findMax2.cc: use a function to print values in an array
      and to find the maximum value in an array

(3) findMax3.cc: use a character array (i.e. a C string)
    to pass in the name of the array we want to print.

    To do that, we'll need this const stuff...

Talk about
   const char * const name

And about
   const char * const a  for arrays in general...


char *arrayname; // no protection 

   if (arrayname = NULL)  // this would be a logic error, not compiler error
   ...

   if (arrayname[0] = 'x') // logic error, not compiler error
   ...

const char * arrayname;
   if (arrayname = NULL)  // this would be a logic error, not compiler error
   ...

   if (arrayname[0] = 'x') // compiler error
   ...

char * const arrayname;  // constant pointer to char 

   if (arrayname = NULL)  // compiler error
   ...

   if (arrayname[0] = 'x') // this would be a logic error, not compiler error
   ...

const char * const arrayname;  // constant pointer to char constant

   if (arrayname = NULL)  // compiler error
   ...

   if (arrayname[0] = 'x') // compiler error
   ...
