Enter 2 to convert from Celsius to Fahrenheit.
        			Your choice is: 
.	After the menu is displayed, the user enters his/her choice. If 
the user enters a character different than 1 or 2, then the program does 
not do anything. 
.	If the user enters 1, then the program displays:
Enter a Fahrenheit temperature to convert to Celsius: 
.	Then the user enters a Fahrenheit temperature and the program 
displays the corresponding Celsius temperature.
.	If the user enters 2, then the program displays:
Enter a Celsius temperature to convert to Fahrenheit: 
.	Then the user enters a Celsius temperature and the program 
displays the corresponding Fahrenheit temperature.
