Hi,
how this two codes work?

Код:

LoadDealerships()
{
	new File:handle, count;
	new filename[64], line[256], s, key[64];
	for(new i=1; i < MAX_DEALERSHIPS; i++)
	{
		format(filename, sizeof(filename), DEALERSHIP_FILE_PATH "d%d.ini", i);
		if(!fexist(filename)) continue;
		handle = fopen(filename, io_read);
		while(fread(handle, line))
		{
			StripNL(line);
			s = strfind(line, "=");
			if(!line[0] || s < 1) continue;
			strmid(key, line, 0, s++);
			if(strcmp(key, "Created") == 0) DealershipCreated[i] = strval(line[s]);
			else if(strcmp(key, "Pos") == 0) sscanf(line[s], "p,fff", DealershipPos[i][0],
				DealershipPos[i][1], DealershipPos[i][2]);
		}
		fclose(handle);
		if(DealershipCreated[i]) count++;
	}
	printf("  Loaded %d dealerships", count);
}

SaveDealership(dealerid)
{
	new filename[64], line[256];
	format(filename, sizeof(filename), DEALERSHIP_FILE_PATH "d%d.ini", dealerid);
	new File:handle = fopen(filename, io_write);
	format(line, sizeof(line), "Created=%d\r\n", DealershipCreated[dealerid]); fwrite(handle, line);
	format(line, sizeof(line), "Pos=%.3f,%.3f,%.3f\r\n", DealershipPos[dealerid][0],
		DealershipPos[dealerid][1], DealershipPos[dealerid][2]);
	fwrite(handle, line);
	fclose(handle);
}
