Tri-Temp — Temperature Conversion Module

This is a module I am creating, debuted at 2:49 AM on 8/29/2025.

Project Intent

This project is intended to do the following:

• Take user input
• Accept a specified temperature unit
• Convert the temperature to the remaining units

This project is coded in Python and C++ as a programming exercise.
Once released, there is no planned long-term afterwork.

Program Restrictions & Running

Python

• Handles numeric input validation internally.

Python (Running)

• Run the program from the repository folder:

python tri_temp.py

C++

• Only receives numeric input for temperature values.
• Non-numeric input will result in a looping prompt.
• This behavior is left as user integrity by design, as numeric stream validation has not yet been covered.

C++ (Running)

• Compile with your preferred C++ toolchain/IDE (example commands vary by system).

Timeline of Work

• 12/15/25 – 12/20/25
  (Delayed due to sickness)

• 12/31/25 – 01/03/26 + 01/04/26
  C++ implementation completed. Python Code completed and tested. Said I wanted it Public ASAP early 01/04/26.

Program Logic

The program follows this logic:

1. Takes user input for temperature and unit.
2. Unit options:
   • C → Celsius
   • K → Kelvin
   • F → Fahrenheit
3. Mathematical formulas remain untouched.
4. Output displays:
   • The base temperature
   • The two converted temperatures
     (rounded to two decimal places)
5. User is prompted to enter a new value or quit.
6. Program exits if the user selects N.

Unit Test List (Manual Verification)

Use these inputs and confirm the expected outputs match (rounded to two decimals). Note: Small floating-point rounding differences may occur depending on runtime; expected values are shown to two decimals.

Test 1 — Freezing Point of Water

Input: 0 C
Expected:

• Base: 0.00 C
• Fahrenheit: 32.00 F
• Kelvin: 273.15 K

Test 2 — Boiling Point of Water

Input: 212 F
Expected:

• Base: 212.00 F
• Celsius: 100.00 C
• Kelvin: 373.15 K

Test 3 — Absolute Zero

Input: 0 K
Expected:

• Base: 0.00 K
• Celsius: -273.15 C
• Fahrenheit: -459.67 F

Test 4 — Room Temperature Sanity Check

Input: 25 C
Expected:

• Base: 25.00 C
• Fahrenheit: 77.00 F
• Kelvin: 298.15 K
