Write a program that gives the user a menu to choose from $$

$1.$ Convert temperature input from the user in degrees Fahrenheit to degrees Celsius

$2.$ Convert temperature input from the user in degrees Celsius to degrees Fahrenheit

$3.$ Quit.

Formulae you will need:$$C $=(5/9)*($F$-32)$ and F $=(9/5)*$ C $+32$

$1.$ Use functions to accomplish $1$ and $2$ above.

$2.$ Use at least one function for each scenario $($i$.$e$.$ converting temperature from degrees Fahrenheit to degrees Celsius and from degrees Celsius to degrees Fahrenheit$).$ You must$$call them from the main$$function$.$ You can use more functions if you see fit to do so$.$

Test the program with the following values:

$68$ degree F $=20$ degree C

$20$ degree C $=68$ degree F

$-22$ degree F $=-30$ degree C

$0$ degree C $=32$ degree F
