🌡️ Temperature Converter (C for practice)

A simple and efficient command-line application written in C that converts temperatures between Celsius and Fahrenheit.

---

📌 Features

• Convert Celsius → Fahrenheit
• Convert Fahrenheit → Celsius
• User-friendly input via terminal
• Handles invalid input gracefully
• Uses switch-case and standard C functions

---

🛠️ Technologies Used

• C Programming Language

• Standard Libraries:

  • stdio.h
  • ctype.h

---

🚀 How It Works

1. User selects the unit type:

   • C for Celsius
   • F for Fahrenheit

2. User enters the temperature value

3. Program performs the conversion

4. Result is displayed instantly

---

🔄 Conversion Formulas

• Celsius to Fahrenheit: F = (C × 9/5) + 32

• Fahrenheit to Celsius: C = (F − 32) × 5/9

---

💻 Sample Run

Is the temperature in (F) or (C)?: C
Enter the temperature in Celsius: 25
Temperature in Fahrenheit: 77.0

Is the temperature in (F) or (C)?: F
Enter the temperature in Fahrenheit: 77
Temperature in Celsius: 25.0

⚠️ Error Handling

• If the user enters an invalid unit:

X is not a valid unit.
