Temperature Data Manager (C)

This project implements a complete temperature data processing system in C, which allows the user to load and manage daily temperature measurements from a file using one of two data structures:

• Binary Search Tree (BST)
• Hash Table with Chaining

The application reads from a file (temp.txt) where each line represents a day's temperature readings in the format:

{"timestamp1": "value1", "timestamp2": "value2", ..., "timestampN": "valueN"}

📦 Features

🔸 Mode Selection

• On launch, the user selects one of the following storage modes:
  • BST by Date
  • BST by Average Temperature
  • Hash Table with Chaining

---

🔹 BST Functionality (Sorted by Date or Avg Temp)

1. In-order traversal display with headers
2. Search for average temperature by date
3. Modify the average temperature of a given date
4. Delete a date's entry
5. Min/Max temperature search (when sorted by temperature)

---

🔹 Hash Table Functionality

1. Search for average temperature by date
2. Modify average temperature for a given date
3. Delete a record by date
4. Exit program

• Hash function: Based on the ASCII sum of the date string modulo m (odd number of buckets)
  • Example:
    Hash("2014-02-13") = (ASCII sum) % 11

▶️ Compilation & Execution

gcc temperature_data_manager.c -o temp_manager

./temp_manager
