Explanation
- Temperature Conversion Functions:
celsiusToFahrenheit(double celsius): This function converts a temperature from Celsius to FahrenheitfahrenheitToCelsius(double fahrenheit): This function converts a temperature from Fahrenheit to Celsius
- Main Function:
- The
main()function starts by presenting the user with two options: converting from Celsius to Fahrenheit or from Fahrenheit to Celsius. - The user is prompted to enter their choice (
1or2). - Depending on the choice, the program asks for the input temperature, performs the conversion using the appropriate function, and then displays the converted temperature.
- If the user enters an invalid option, an error message is displayed.
