    You are missing a closing brace at the end of the function "void hotel::submenu()".
    Code:
    		cin>>continues;
		if(continues=='y'||continues=='Y')
			menu();
	}
}// need a closing brace

void hotel::bill()
{

    Your menu function is kinda ugly in its implementation. It recursively calls itself needlessly either directly or through the functions that it calls. The menu function should be a loop that continuously processes user input and either exits or call the appropriate functions submenu/bill. These functions should not call menu but rather they will return to the menu function once they exit whereupon control should return to the loop displaying the menu options and processing user input.

    Code:
    void hotel::submenu()
{
    information n;
    char choose;
    int number=0;
    int room;
    char continues;
    outfile.open (filename,ios::out|ios::app);
    outfile.close();
    What is the purpose of opening and then immediately closing the file?

    Code:
    class information : public hotel
{
    Why is this information class being derived from the hotel class?

    The indentation/alignment makes looking through your code difficult. Fix the indentation/alignment and repost. Replace tabs with an appropriate number of spaces. Use the "Preview Post" button to your advantage and use the opportunity to keep at it until you post is nicely formatted.

    I noticed something on your code:
    Code:
    #include<iostream>
#include<conio.h>
#include<cctype>
#include<string>
#include<stdlib.h>
#include<fstream>
#include<iomanip>
#include<time.h>
#include<string>
#include<stdio.h>
    Why sometimes use .h (C-way) and sometimes without .h (C++-way)?

    Because conio.h has no 'without .h' version. stdlib.h and stdio.h, on the other hand, should be replaced with <cstdlib> and <cstdio>.
    Just Google It. √

    What about <time.h> replaced with <ctime>?
