[prog] Re: C++

Okay last attempt from staying up all night, it still doesn't quite 
work and I can't figure
out what the error messages mean precisely, so once more if anyone can 
see a way to
get this to work I'll be eternally grateful, right now I'm just 
somewhere past complete
exhaustion : ) one problem I know is I have no idea how to get this to 
write to a file.
anyone? bueller? : )

here are the error messages:
Compiling...

this is line 20:

      21     // create a new cd object

      23     title = stitle;
      24     genre = sgenre;
      25     year = iyear;


this is line 29:

here's the current version of the program:
#include <iostream>
using namespace std;

class cd {

     string title;
     int year;
     string genre;
	
	
private:
     cd(string artist, string title, string genre, int year);
     void showCD();
	void saveCDLibrary();
	void printCDLibrary();


	void cd (string sartist, string stitle, string sgenre, int iyear) {
     // create a new cd object
     artist = sartist;
     title = stitle;
     genre = sgenre;
     year = iyear;

};

	void showCD() {
     // print a cd object
     cout << artist << " " << genre << " " << title << " " << year << 
endl;
}

void saveCDLibrary(cd cdLibrary[], int length) {
     // need a fileIO stream of some sort.
     for (int i; i < length; i++) {
         cin << cdLibrary[i].showCD();
     }
}

void printCDLibrary(cd cdLibrary[], int length) {
     // This maybe needs sorted...
	
     for (int i; i < length; i++) {
         cout << cdLibrary[i].showCD();
     }
}

void readCDLibrary(cd cdLibrary, int length) {
     string input, artist, title, genre;
     int year;
	
     // Open the file ?	
     for (int i = 0; i < length; i++) {
         inputstream >> input;
		
         // artist, title, genre, year
		
         cdLibrary[i] = new cd(artist, title, genre, year);
     }
}


int main()
{
     int CDcount = 0;
     const int LIBRARY_SIZE = 10;
     string artist, title, genre;
     int year;
     cd cdLibrary[LIBRARY_SIZE];
	
     // Ask if they want to read the CDs from a file or enter new
     // data:
	
     cout << "Read from file (1) or Enter new data (0)? ";
     cin >> ans;
	
     if (ans) {
         // read from the file?
		
         readCDLibrary(cdLibrary, LIBRARY_SIZE);
		
     } else {
         // read in information about CDs
         while (cdCount < LIBRARY_SIZE) {
             cout << "Enter CD Information:" << endl;
             cout << "Enter year: (0 to quit)";
             cin >> year;
             if (year == 0) { break; }
             cout << "Enter artist: ";
             cin >> artist;
             cout << "Enter title: ";
             cin >> title;
             cout << "Enter genre: ";
             cin >> genre;
			
             cdLibrary[cdCount] = new cd(artist, title, genre, year);
             cdCount++;
         }
     }
	
     saveCDLibrary(cdLibrary, LIBRARY_SIZE);
     printCDLibrary(cdLibrary, LIBRARY_SIZE);
	
	
     return 0;
}
