Homework 5 — Design and Implementation of a Simple Tinder
In this assignment you will develop a simple online dating application which mimics some of the features provided by Tinder. Please read the entire handout before starting to code the assignment.
Learning Objectives
- Get familiar with a commonly used data structure - linked lists.
- Practice creating and manipulating linked lists without using the std::list library.
Background
Tinder allows users to view other users' profiles, and users can swipe right or swipe left. Swipe right means like or accept someone, whereas swipe left means reject them. When two users both express interest by swiping right, the app establishes a match between them, allowing them to initiate conversations and interact further.
In addition, users will only see nearby users, and they can filter whom they want to see, based on age, height, and distance.
In this assignment you will be implementing these two features.

The above is the first 4 lines of the users.txt file. It has 14 fields, separated by a space. And these 14 fields are:
- User's name
- User's age
- User's gender
- User's phone number
- User's profession
- User's school
- User's current latitude
- User's current longitude
- Is Premium User or not
- User's preference on age: minimum age
- User's preference on age: maximum age
- User's setting on max distance
- User's setting on interested gender
In case you are not familiar with these dating apps or have not used Tinder, following are two randomly selected Tinder pictures (downloaded from the Internet, sorry Samantha!).
The last 3 fields will only be meaningful if a ride request is assigned to this driver. In this assignment, we assume that drivers will accept the request whenever it is assigned to this driver.
Specification
Your program will support four commands.
- show profiles match with a user's preference.
- show all matches to a user.
- show all users who swiped right on this user - this feature is only available to premium users.
More details about each of these four commands are given below.
Show Profiles
When the user (here, phoneNumber is this user's phone number) runs this command:
nydate.exe input.txt output.txt phoneNumber show
your program should show all profiles which match with this user's preference on age, gender, and distance. All these profiles should be printed into the output file.
Show Matches
When the user (here, phoneNumber is this user's phone number) runs this command:
nydate.exe input.txt output.txt phoneNumber match
your program should show profiles of all users who match with this user. All these profiles should be printed into the output file. The definition of match is when two users both express interest by swiping right on each other.
Show All Users Who Swiped Right on This User
When the user (here, phoneNumber is this user's phone number) runs this command:
nydate.exe input.txt output.txt phoneNumber like
your program should show profiles of all users who likes this user. All these profiles should be printed into the output file. The definition of like is when a user swipes right on another user. Just like on Tinder, this feature is only available to premium users who pays a monthly membership fee. Thus, if this user is not a premium user, your program should just print this message to the output file:
Only premium users can view who liked you.
Program Requirements & Submission Details
Use good coding style when you design and implement your program. Organize your program into functions: don’t put all the code in main! Be sure to read the Homework Policies as you put the finishing touches on your solution. Be sure to make up new test cases to fully debug your program and don’t forget to comment your code! Use the provided template README.txt file for notes you want the grader to read. You must do this assignment on your own, as described in the Collaboration Policy & Academic Integrity page. If you did discuss the problem or error messages, etc. with anyone, please list their names in your README.txt file.
