1,2,& 3 D arrays
	Declare
	initialize
	passing to functoins
	use nested for loops with them

	Find the address of a given element in an array
	
Pointers - a variable that holds an address
	declare - char* p = NULL;
	p = strchr(string, 'A');
	NULL - the address zero - 
		used to mean that the pointer is not pointing
		at anyting useful

	if(p != NULL)

Text Files
	define
	diferentiate with Binary Files
	Examples (.txt, .cpp, .html)

Binary Files
	Examples (images, sound files, .exe)

C++ File IO
	#include<fstream>
	ofstream fout;
	ifstream fin;

	file handle - the variable used to access a file
	
	handle.open("c:\directory\junk.txt");
	handle.close();
	
	ofstream fout ("c:\directory\junk.txt");	
	fout.close();

	fout << 234;
	fout << variable;

	fin >> variable;
	fin.getline(string,100);
	fin.get(string, 100);

	Read to the end of a file 
	fin.eof();

CGI - Common Gateway Interface

	HTML - HyperText Markup Language
	URL - Uniform Resource Locator
	HTTP - HyperText Transfer Protocol

	POST
		Environment variable - CONTENT_LENGTH
		char* cl = getenv("CONTENT_LENGTH");
		when cl is NULL it must be a GET
		when cl is not NULL it must be a POST

		int i = atoi(cl);
		Read parameters from standard input
		cin.get(postData, i + 1);
		
		Format of the post Data
		name=value&OtherName=value&name3=value
	
	GET
		Environment variable - QUERY_STRING
		char* queryString = getenv("QUERY_STRING);

		Query string is passed from the web browser
		to the webServer as part of the URL.  
		After a ?


		Format of the query String
		name=value&OtherName=value&name3=value
