🌟 Features at a Glance

🟢 Park	🔴 Unpark	🔍 Find	⚡ Smart Park
Park by block / row / slot	Remove by exact location	Search by license plate	Auto-finds nearest empty slot

📈 Grow Slots	📉 Shrink Slots	👁️ View Lot	🔔 Toasts
Expand any row dynamically	Shrink if trailing slots empty	Full visual board with bars	Live feedback notifications

🖥️ UI Panels

The application opens at 1280 × 780 with a dark navy theme and a 7-button sidebar. Each button switches the right panel:

#	Panel	Colour	Description
1	View Lot	🔵 Cyan	Scrollable visual board — all blocks, rows, slots
2	Park Vehicle	🟢 Green	Enter block / row / slot + license plate
3	Unpark	🔴 Red	Remove vehicle by exact location
4	Find Vehicle	🔵 Cyan	Search the entire lot by license plate
5	Smart Park	🟡 Yellow	Auto-allocate nearest empty slot to a block
6	Grow Slots	🔵 Cyan	Increase slot count for any row
7	Shrink Slots	🔴 Red	Decrease slot count (only if trailing slots empty)

🎨 Visual Design

Element	Detail
Background	Deep navy #05080A — zero eye strain
Accent colour	Cyan #00D4FF — active inputs, labels, borders
Empty slot	Dark green background + green border + P icon
Occupied slot	Dark red background + red border + CAR + plate text
Highlighted slot	Gold border + gold background — result of Find / Smart Park
Occupancy bar	Green → Yellow → Red as the block fills up
Toast notifications	Slide-in top-right messages with 3-second fade timer

⚙️ Core Architecture

Data Structure

The entire lot is stored as a 4-dimensional dynamic char array:

char**** ptr
  └── ptr[block][row][slot] → "EMPTY" or "ABC-123" (license plate)

Supporting arrays:

int*  rpb     // rows per block
int** spb     // slots per block per row

Key Functions

void allocateLot(ParkingLot& lot, ...)    // Build full 4D structure at setup
void freeLot(ParkingLot& lot)             // Recursively deallocate everything

bool isSlotEmpty(...)                     // Check if a slot holds "EMPTY"
void emptySlot(...)                       // Write "EMPTY" into a slot

vector<int> findCar(lot, plate)           // Scan all slots → return {b, r, s}
vector<int> smartFind(lot, block)         // Nearest empty slot by Euclidean distance

void growRow(lot, block, row, newSlots)   // Reallocate row with more slots
bool shrinkRow(lot, block, row, newSlots) // Shrink only if trailing slots are empty

void getStats(lot, total, occupied, free) // Aggregate counts across all blocks

Smart Allocation Formula

// Each slot's position relative to block entrance:
double x = slot_index  * 8.0;   // 8 ft per slot width
double y = row_index   * 16.0;  // 16 ft per row depth

double distance = sqrt(x*x + y*y);
// → picks the slot with minimum distance

🚀 Setup Flow

1. Enter number of blocks
2. Click GENERATE STRUCTURE
3. For each block → enter number of rows + slots per row
4. Click CREATE LOT
5. Full parking dashboard opens

🛠️ How to Build & Run

🐧 Linux / 🍎 macOS

# Clone
git clone https://github.com/Abd-Abdullah83/Parking-System.git
cd Parking-System

# Compile
g++ -std=c++17 CarPark.cpp ParkingClass.cpp -o parking \
    -lsfml-graphics -lsfml-window -lsfml-system

# Run
./parking

🪟 Windows (MinGW)

g++ -std=c++17 CarPark.cpp ParkingClass.cpp -o parking.exe ^
    -lsfml-graphics -lsfml-window -lsfml-system

parking.exe

Note

SFML 2.x must be installed.

• Ubuntu → sudo apt install libsfml-dev
• macOS → brew install sfml
• Windows → sfml-dev.org

Warning

The app searches for a font at startup in this order: arial.ttf → fonts/arial.ttf → C:/Windows/Fonts/arial.ttf → system fonts. If none are found the program exits with an error. Place arial.ttf next to the executable to be safe.

🕹️ How to Use

Parking a Vehicle

1. Click PARK VEHICLE in the sidebar
2. Enter Block number, Row number, Slot number
3. Enter License plate  e.g. ABC-123
4. Click PARK VEHICLE — green toast confirms success

Smart Parking

1. Click SMART PARK
2. Enter the desired Block number + License plate
3. Click FIND + PARK
4. System calculates nearest empty slot automatically
5. Slot highlights in gold on the board

Finding a Vehicle

1. Click FIND VEHICLE
2. Enter the license plate
3. Click SEARCH
4. Result shows Block / Row / Slot — highlighted gold on board

Growing / Shrinking a Row

GROW   → Enter block, row, new slot count → always succeeds
SHRINK → Enter block, row, new slot count → fails if occupied slots would be removed

📐 Technical Highlights

Concept	Implementation
4D dynamic array	char**** — blocks → rows → slots → plate string
Manual memory management	new / delete[] with full recursive cleanup in freeLot()
Dynamic resize	growRow() and shrinkRow() reallocate in-place with data preservation
Euclidean smart search	Minimises √(x²+y²) over all empty slots per block
Toast system	Timed overlay messages with per-operation colour coding
Input validation	Numbers-only fields enforced at TextInput level
Occupancy bar	Per-block fill bar changes Green → Yellow → Red
