	// Enter the main program here

//*** 1. opening a file in the same directory as the code using a fixed name

//       In is the file variable; "circledata.txt" is the name of the file on disk

//		 Look at the file. Each line has 6 integers intended to be x, y, radius, R, G, B

	ifstream In("circledata.txt");  // input file stream

	int x, y, radius, R, G, B;

	while(In){

		In >> x >> y >> radius >> R >> G >> B; // works just like cin

		SetForeColor(R, G, B);

		PaintCircle(x, y, radius);

	}



//*** 2. You can also type in a file name

//       The function GetInputFile shows you how to do that.

//       Look at the code and explain it.

//       Here is some code that calls GetInputFile

	ifstream myFile;

	GetInputFile(myFile);

	// Read the file one char at a time and write it to cout

	// Run this program 3 times and try entering:

	// twinkle.txt

	// circledata.txt

	// Shell.cpp	(Yes, the program can read itself!)

	char ch;

	while (myFile.get(ch))

		cout << ch;

// How do you count the number of characters in the file?



//*** 3. Write to a file

	ofstream outFile;

	ifstream inFile;

	GetOutputFile(outFile); // Create an output file

	GetInputFile(inFile);   // Open Input file, myFile

	// copy input file to output file

	while (inFile.get(ch))

		outFile << ch;

//*** 4. Change this code so that the new file will have a * wherever the old file had a blank	



//////////



	// The lines below make sure that the graphics windows remain open just

	// before the program terminates



	PressReturn("\nThe main program is about to terminate\n");



	return 0;
