#include "stdio.h"
#include "fstream.h"
class CText{
public:
int x;
int y;
int z;
int r;
int g;
int b;
char text[8];
};
void main ()
{
fstream FioObject;
char buf[256];
cout << "Enter some text\n";
cin >> buf;
cout << "Text Saved\n";
FioObject.open("text.txt", ios::out);
FioObject << buf;
CText sometext;
sometext.x=1;
sometext.y=7;
sometext.z=5;
sometext.r=032;
sometext.g=120;
sometext.b=022;
FioObject << sometext.x << sometext.y << sometext.z << sometext.r << sometext.z << sometext.g << sometext.b;
FioObject << "Hello everybody";
};
So I know how to do text output with fstream, but what about with stdio? and how do I input?
Thanks in advance.

Is there any place I can get a good tutorial on file I/O?? I''m intrested in both binary and text. I have been able to ouput single characters to a file:
C++''s iostream library is mostly text oriented, and quite flexible. Binary file I/O is supported, but more limited than text. It can be a bit daunting as well 
stdin and stdout are represented by the cin and cout objects, resp.
For reading from a file you can create a ifstream object. It''s opened as text as default. To read from it, use the >> operator.
If you want to read/write classes, overload the << and >> operator for the specific class. For example, for <<:
ostream& operator<<(ostream&, const Class&)
{ ... }
This function should be declared as a friend of the class you want to use it for. You can then write the class to an output stream like this:
Class c;
ofstream f("test.txt");
f << c;
cout << c;
The subject is really too large to discuss here in detail, so I suggest you get a good book on C++ that discusses the IOstream library. Maybe your IDE comes with help about the IOstream library.

Thanks for the help. I read the section on IO streams on Sams Teach Yourself.. c++..24 days on Informit.com
Its been a great help, and your direct writeing of classes is cool. Ill try it all out
