Temperature Conversion Program

Overview

This program allows users to convert temperatures between Celsius, Fahrenheit, and Kelvin. It provides a user-friendly menu-driven interface to select the input temperature scale, enter a temperature value, and choose the desired output scale. The program also includes data validation and advanced features like multi-step conversions.

Features

1. Conversion Options:
   • Celsius to Fahrenheit and Kelvin.
   • Fahrenheit to Celsius and Kelvin.
   • Kelvin to Celsius and Fahrenheit.
2. Advanced Features:
   • Multi-step conversion (e.g., Celsius to Fahrenheit to Kelvin).
   • Continuous mode to allow multiple conversions without restarting the program.
3. Input Validation:
   • Ensures valid temperature values are provided.
   • Displays warnings for physically impossible temperatures in certain scales (e.g., temperatures below absolute zero in Kelvin).

How to Use

1. Menu Options:

   • Choose the input scale.
   • Enter the temperature value.
   • Select the output scale(s) for conversion.

2. Example Usage:

   • Input: Convert 25°C to Fahrenheit and Kelvin.
   • Output:

     25°C = 77°F
     25°C = 298.15K

Compilation and Execution

1. Save the program code in a file named temperature_conversion.c.
2. Open a terminal and compile the program:

   gcc temperature_conversion.c -o temp_converter

3. Run the program:

   ./temp_converter

Code Walkthrough

1. Main Functionality:

   • Displays a menu with input and output options.
   • Reads user input and validates it.
   • Calls the appropriate conversion function(s).

2. Conversion Functions:

   • celsiusToFahrenheit()
   • celsiusToKelvin()
   • fahrenheitToCelsius()
   • fahrenheitToKelvin()
   • kelvinToCelsius()
   • kelvinToFahrenheit()

3. Modular Design:

   • Each conversion operation is handled by a separate function for clarity and maintainability.
   • User input handling and temperature validation are centralized for better error management.

Future Enhancements

1. Add graphical interface for easier interaction.
2. Include unit testing for robust validation.
3. Support for additional temperature scales (e.g., Rankine).
