If the letter is f, the program should treat the number entered as temperature in degrees Celsius and convert it into the temperature in degree Fahrenheit and print a suitable message. If the letter is c, the program should consider the number as Fahrenheit temperature and convert it to Celsius temperature and print a suitable message. The program should display error message and then exit if the user enters any other letter. Use c++ language to implement this program. [Marks = 10] Formulas: Celsius to Fahrenheit: 9.0/5.0 * value + 32 Fahrenheit to Celsius: 5.0/9.0 * (value-32) Note: Do this using Switch statement.
