    printf(\"Enter your fahrenheit, we\'ll covnvert          


        

Answer 1

Short answer: Operations on integers return integers even if the variable you store the result on is a double. Divisions between integers are truncated.

You should write this instead:

c = 5.0/9.0 * (fahrenheit - 32.0);

Adding a ".0" (or even just a ".") to your constant makes them floating point values.
