Binary Files
	Text vs. binary
	Direct access files
	fin.seekg(n);
	fout.seekp(n);
	fin.read((char*)&i,4);
		& - the address of a variable 

	Describe the format of a bitmap file
		The three major categories 
		How the pixels are laid out (BGR)
		Each row has an even multiple of 4 bytes
		
		Know your bitmap math

5 pixles wide by 10 pixles tall
how may bytes are in each row?	16
how may bytes are in the image data?160
how may bytes are in the file header? 14
how may bytes are in the info header? 40
how may bytes are in the whole file? 214

	Be able to tell if a file exists for reading. 
		if(fin.fail())

string
	declare
	assign a value to a string  s = “asdf”;
	compare
	length	- s.length();
	find a string in a string   - s.find(s2); - returns the index where s2 is found in s
string:: npos if it is not found
	get a string from the user that has white-space  
			getline(cin,s);

Structs
	Define
	struct FileHeader
{
	char bfType[3];
	unsigned int bfSize;
	unsigned short bfReserved1;
	unsigned short bfReserved2;
	unsigned int bfOffBits;
};

	User defined data type
	Object
	FileHeader variableName;
	Pass an object to a function
		By reference for efficiency sake
		If you do not need to change it make it a const reference

	Be able to access member variables of an object (be able use the .)
	
	Constructor 
	Destructor

Dynamic Memory Allocation
	new
	delete
	declare a pointer to any datatype
