classes in dev c++

[mandm911]

I need to write a program that tells the user to input one fraction(numerator and denominator), along with two other fractions that are given. The program must +,-,/,*,reduce,reciprocate, and find if the given fractions are greater less than or equal to one another. I have no clue of even where to start for the main program. heres what i got

If possible, please post a reasonable compilable length of code using code tags. You will likely get many more responses if people can look at your code directly in the browser versus having to download and open it.

Please use code tags. That is

[ code ]
your code
[ /code ]

(but remove the spaces between the brackets and the word "code")
