This is what the program needs to do:
Enter a temperature: 32.4
Enter 'C' for Celsius or 'F' for Fahrenheit: C
Choose a conversion ('C' for Celsius or 'F' for Fahrenheit): F
The temperature is: 90.3 F.
How would I store the input when it asks for C or F, then use it to activate the correct equation to convert the inputted temp to C or F?
