Apartment Evaluator

A C++ decision-support tool that ranks apartments using a weighted multi-criteria score of price, living space and noise level. It has an interactive command-line app and a small web interface built on cpp-httplib.

=== Ranked Apartments (Best to Worst) ===
----------------------------------------
1. Suburban House
2. Quiet Apartment
3. Downtown Studio
4. City Loft
5. Luxury Penthouse

Weights Used:
  Price:  40%
  Space:  35%
  Noise:  25%

Features

• Weighted scoring: price (lower is better), space (higher is better), noise (lower is better)
• Adjustable weights: customize what matters to you; weights are normalized to 100%
• Weight profiles: save and load your preferences to and from a file
• CSV import: load a list of apartments in one go
• Interactive CLI: add, view, rank and clear apartments from a menu
• Web interface: add apartments, tweak weights and see rankings in the browser

Build & run

Requires a C++17 compiler (g++ or clang) and make.

make          # build both the CLI and the web server into build/
make run      # start the CLI
make web      # start the web server on http://localhost:8080
make clean    # remove build output

How the score works

Each apartment gets a weighted cost score, and the lowest score ranks first:

score = price × w_price + (1000 − space) × w_space + noise × w_noise

Criterion	Default weight	Better when
Price	40%	lower
Space	35%	higher (sq ft, measured against 1000)
Noise	25%	lower (0–100 scale)

CLI menu

1. Add apartment
2. View all apartments
3. Rank apartments
4. Customize weights
5. Load apartments from file
6. Save weights profile
7. Load weights profile
8. Clear all apartments
9. Exit

CSV format

ID,Price,Space,Noise
Downtown Studio,1800,650,45
Suburban House,1200,1100,25
City Loft,2200,800,60

A sample file is included as apartments.csv, and weights_profile.txt is an example saved weight profile.

Roadmap

• CSV upload in the web interface (currently CLI only)
• Location and commute-time criteria
• Amenities scoring
• Normalize criteria to a common scale (raw price currently outweighs noise)
• Unit tests
