FILE HANDLING (patient file system)

[nunii07]

Please help!! The program doesn't run and i've tried to compare it to some forums i've searched here but still doesn't seem to fix the problem...

here is the complete code of the program:

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

struct file{
	int fnum;
	char fname[50], lname[50];
	char cnum[50];
	int balance, total;
};

file f;
//int i, list,ans, searchnum, delnum, x, y;
int ans, list, i, searchnum;
int cons, es, minsur, majsur;
char others[50], name[50], yon, noy;
int pay, oprice, balpaid;

void newLine();
void line(char, int);
void procedure2();
void procedure();
void addfile();



int main()
{
	ofstream fout;
	fout.open("d:\\hayamieyecenter.txt");
	int choice, list=1;
	f.total=0;
	while(1){

You are attempting to change an unmodifiable l-value.

It's an l-value, but you cannot assign anything to it.

"==" would not work for this either. "==" is an equivalency statement. It checks whether the values it's equating are equal or not, it does not set values.
