Can't get my bubble sort to work...

[anthonyajax]

I'm needing my program to sort by last name, but I'm not seeming to get that at all. I'm not sure what I'm doing wrong or missing. Any help or pointers?

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

struct Roster 
{
	string lname;
	string fname;
	char cheese;
};

const int MAXSIZE = 80;
char * givemename(char* fn);
int recordcount(const char * filename);

struct Roster* readarray(const int rcount, char *filename);
void readsurvey(const int rcount, const char * filename, struct Roster *);
int countp(const int rcount, struct Roster *MyRoster);
int countc(const int rcount, struct Roster *MyRoster);
void swap(struct Roster *MyRoster1,struct Roster * MyRoster2);
void BubbleSort (const int rcount, struct Roster*MyRoster);
void DrawRecords(const int rcount, struct Roster*MyRoster);
int drawsummary(const int rcount,const int pcount, const int ccount);

int main(void)
{
	char * filename = new char [MAXSIZE] ; 
	struct Roster * MyRoster;
	struct Roster *PassedRoster;
	int rcount=0, pcount=0, ccount=0;
	
	filename=givemename(filename); 
	rcount = recordcount(filename); 
	MyRoster = new struct Roster[rcount]; 
	readsurvey(rcount, filename, MyRoster);
	pcount = countp(rcount,MyRoster);
	ccount = countc(rcount,MyRoster);
	BubbleSort (rcount, MyRoster);
	DrawRecords(rcount,MyRoster);
	drawsummary(rcount,pcount,ccount);
	return 0;
}

{

	while(!myfile.is_open())

{
	int count = 0;
	for (int i = 0; i<=rcount; i++)

				count ++ ;

	return count;
