C++ Temperature Conversion (C++ Functions)

tempConversion.cpp

/*Write a function named celsius that accepts a Fahrenheit temperature as an argument. The function should return the temperature, 
converted to Celsius.
Demonstrate the function by calling it in a loop that displays a table of the Fahrenheit temperatures 0 through 20 
and their Celsius equivalents.

C = 5/9 * (F-32)
