//
// Program:  capitalize.
//
// Purpose:  test recursive function to convert all characters in
//   a string to uppercase.
//
// Input:
//   a line of text from standard input.
// Output:
//   the same text, converted to uppercase.
//   to standard output.
#include <iostream.h>
#include <stdlib.h>
#include <ctype.h>

// Function to convert string to uppercase.
// Pre: "s" contains a null-terminated string; n >= 0 and < length of s.
// Post:  all characters in s at position n through the end of "s"
//          have been converted to uppercase.
// ADD YOUR FUNCTION HERE.  
// The prototype should be of the form
//   ?? capitalize(?? s, ?? n);
// (Replace "??" with appropriate types.)
