Need help reading in multiple strings from file

sirjames2004 (25)
I have a class composed of three string type data members. I need two functions that will read and write that data directly from that class to file. The output function works just fine. I used it with test data earlier. It's the input function I'm having issues with. Gives me the following syntax errors:

mjccourse.cpp: In function ‘std::ifstream& operator>>(std::ifstream&, const MJCCourse&)’:
mjccourse.cpp:47: error: no match for ‘operator>>’ in ‘lhs >> rhs->MJCCourse::dept’

};

// mjcc1main.cpp
#include <cstdlib> // for exit()

#include "mjccourse.h"

int main()
{
	std::ifstream infile;
	std::ofstream outfile;
	infile.open("cour2331.txt");
	if(!infile.good())
	{
		std::cerr << "Unable to open cour2331.txt file for reading!" << std::endl;
		exit(1);
	}
	outfile.open("mjcclist.txt");
	if(!outfile.good())
	{
		std::cerr << "Unable to open mjcclist.txt file for editing!" << std::endl;
		exit(2);
	}
	
	MJCCourse t1;
	infile >> t1;
	outfile << t1;
	
	infile.close();
	outfile.close();
	return 0;
}


First five lines from input file. Also, I'm just trying to read in one line in main for now, until I know what I'm doing.

Nevermind. I was passing by a constant reference in my '>>' function. Should have been this way:

std::ifstream& operator>>(std::ifstream &lhs, const MJCCourse &rhs)
