Using fstreams to write and read data #1

	fout.open("output.txt"); //opening a new file in which we will save the data
 
	int num = 1500; //a number to save
	char name[] = "John Doe"; //we could use a 'string' instead of 'char'
 
        //using the ''<<' operator we save the data we want
	fout << "Here is a number: " << num << "n";
	fout << "Now here is a string: " << name << "n";

         * In essense all data in the stream buffer that have not been written yet in the file
         * are now written. This a good way to update the file without using the 'close()' function.
