Use C only Please include comments and pre post conditions I

15 object in the class should have two integer values that define the rational number: the numerator and the denominator. For example, the fraction, 5/6 would have a denominator of 5 and a nu- merator of 6. Include a constructor with two argu- ments that can be used to set the numerator and
