adjusting a code for Linuxconio.h

Hi All,

I am using a book to learn C++. Unfortunately the book, sometimes, uses the maddening phrase, #include <conio.h>, which is a M$ related file and not a part of STL, in some of its examples.

My question is: How would you modify the following code so it would compile and run on Linux? Here is the code:

Code:

// chcount.cpp
// counts characters and words typed in
#include <iostream>
using namespace std;
#include <conio.h>             //for getche()
int main()
   {
   int chcount=0;              //counts non-space characters
   int wdcount=1;              //counts spaces between words
   char ch = �a';              //ensure it isn't �\r'
   cout << �Enter a phrase: �;
   while( ch != �\r' )         //loop until Enter typed
      {
      ch = getche();          //read one character
      if( ch==' � )           //if it's a space
      wdcount++;              //count a word
      else                    //otherwise,
      chcount++;              //count a character
      }                       //display results
   cout << �\nWords=� << wdcount << endl
        << �Letters=� << (chcount-1) << endl;
   return 0;
   }

The code is primitive, I know, as I got it from the first couple of chapters of this book.

Thank you so much in advance,

eager

PS.
I am also open to any suggestions for more books, although I find the current one very useful, except this conio.h file!

domdocument.getelementbyid

DOMDOCUMENT.GETELEMENTBYID(3)						 1					     DOMDOCUMENT.GETELEMENTBYID(3)

DOMDocument::getElementById - Searches for an element with a certain id

SYNOPSIS

       public DOMElement DOMDocument::getElementById (string  $elementId)

DESCRIPTION

	This function is similar to "DOMDocument::getElementsByTagName" but searches for an element with a given id.

	For  this  function  to  work,	you will need either to set some ID attributes with "DOMElement::setIdAttribute" or a DTD which defines an
       attribute to be of type ID. In the later case, you will need to validate your document with "DOMDocument::validate" or  DOMDocument::$vali-
       dateOnParse before using this function.

PARAMETERS

	      o $elementId
		- The unique id value for an element.

RETURN VALUES

	Returns the DOMElement or NULL if the element is not found.

EXAMPLES

       Example #1

	      DOMDocument::getElementById() Example

	      The following examples use book.xml which contains the following:

	      <?xml version="1.0" encoding="UTF-8"?>
	      <!DOCTYPE books [
		<!ELEMENT books   (book+)>
		<!ELEMENT book	  (title, author+, xhtml:blurb?)>
		<!ELEMENT title   (#PCDATA)>
		<!ELEMENT blurb   (#PCDATA)>
		<!ELEMENT author  (#PCDATA)>
		<!ATTLIST books   xmlns        CDATA  #IMPLIED>
		<!ATTLIST books   xmlns:xhtml  CDATA  #IMPLIED>
		<!ATTLIST book	  id	       ID     #IMPLIED>
		<!ATTLIST author  email        CDATA  #IMPLIED>
	      ]>
	      <?xml-stylesheet type="text/xsl" href="style.xsl"?>
	      <books xmlns="http://books.php/" xmlns:xhtml="http://www.w3.org/1999/xhtml">
		<book id="php-basics">

		  <author email="jim.smith@basics.php">Jim Smith</author>

		</book>
	      </books>

	      <?php

	      $doc = new DomDocument;

	      // We need to validate our document before refering to the id
	      $doc->validateOnParse = true;
	      $doc->Load('book.xml');

	      echo "The element whose id is 'php-basics' is: " . $doc->getElementById('php-basics')->tagName . "
";

	      ?>

	      The above example will output:

	      The element whose id is 'php-basics' is: book
