To fully adapt this topic and report, we would like to express our sincere thanks to 
lecturer, associate professor Hoang Van Dung, who directly supported us throughout the 
process of working on the topic. We appreciate you for guiding us to complete this topic, 
always answer questions and provide timely comments and corrections, help us overcome 
our shortcomings and complete it on time. 
We finished the topic and report in a short period of time, with lack of knowledge 
and experience in implementing a software project. Therefore, there will be some 
unpredictable mising from us, so we look forward to receive comments from you so that 
we can do better for our next projects. 
Finally, we respectfully wish all teachers good health and success in the career of 
cultivating people. Once again we sincerely thank you.      lOMoAR cPSD| 58605085

1. Reason for choosing topic: 
Technology plays a huge role in our everyday lives. It has also become integrated into 
the daily operations of hotel management. By leveraging the latest technologies, 
businesses can streamline operations, increase efficiency, and improve customer service. 
This helps to reduce costs, increase revenue, and ensure long-term profitability. Therefore, 
our group decided to choose the topic which to design data structures, algorithms and 
build a hotel management software. Applying technology to hotel management help user 
to optimize the amount of manual management on paper that waste lots of time, narrow 
storage space, avoid losing data, reduce costs and human resources, so that improve work 
efficiency and product quality.  2. Software feature: 
- To login as a staff in a hotel 
- Can manage the hotel as a manager 
- Update information (ID, Name, Password, Address, Age, Gender, Day Joined)      lOMoAR cPSD| 58605085 - Update room ( ) 
 Decide to let the guest rent, book or return the room or not  - Caculate income  3. Expected interface: 
- Menu to choose which position to login as (manager, accountant, security…) 
- Login console (Type ID, Pasword)  - Manager interface 
+ Can hire or fired the staff, can search for other staff ìnormation  - Receptionist interface 
+ Can see the room status (rented/booked/empty) so that decide to let the guest rent or  book the room  - Accountant interface 
+ To caculate revenue and expenditure  - Service staff interface 
+ Guest can use the service so that the income will increase

1.2. Task division table  B. CONTENT 
1. Project descriptions: 
A hotel need to manage and control the people who work in the hotel and arrange all 
the rooms in the hotel, so that it needs to have a software to manage the manager, the 
accountant, the receptionist, the service staff and rooms including these information: 
- All the staffs and managers at login console such as account, password,  information, salary 
- The manager such as edit manager list, edit every staff list and check the hotel  income 
- The receptionist such as rent room, book room, reserve room, show all room 
- The service staff such as using the service 
- Rooms such as ID, type, status, day begin, day end, money 
2. Background knowledge: 
2.1. Programming method: 
Data Structures and Algorithmsin introduce abstract concepts for data organization 
and manipulation, to show how these concepts are useful in problem solving. 
- Basic – used data structures: Lists, Stacks, Queues, Trees, Hash tables. 
- Algorithms in data structures: Sorting, searching, inserting, deleting. 
- Apply data structures to solve practical problems -  Programming language:  C++  2.2. Linked list:      lOMoAR cPSD| 58605085
Linked list is using a structure which allows to store elements in a list 
A linked list is made of nodes that are pointing to each other 
- Link: each link of linked list can store data called an element 
- Next: every link of linked list store a link to the next element called Next 
- Head: a linked list such as links link to first element called Head   
2.1. Linked list presentation 
Linked list’s basic functions: 
- Insertion: insert an item at the beginning, at the end, after a node 
- Removing: delete an item at the beginning, at the end, after a node - Searching:  Search a node in a list 
2.3. Multi-Linked list: 
- Inserting into this structure is very much like inserting the same node into two 
separate lists. In multi-linked lists it is quite common to have back-pointers
