// Fig. 8.11: fig08_11.cpp
// Printing a string one character at a time using
// a non-constant pointer to constant data.
#include <iostream>
using std::cout;
using std::endl;

void printCharacters( const char * ); // print using pointer to const data

int main()
{
   const char phrase[] = "print characters of a string";

   cout << "The string is:\n";
   printCharacters( phrase ); // print characters in phrase
   cout << endl;
   return 0; // indicates successful termination
} // end main

// sPtr can be modified, but it cannot modify the character to which
// it points, i.e., sPtr is a "read-only" pointer
void printCharacters( const char *sPtr )
{
   for ( ; *sPtr != '\0'; sPtr++ ) // no initialization
      cout << *sPtr; // display character without modification
} // end function printCharacters
