Define a class for rational numbers. A rational number is a number that can be represented as the quotient of two integers. For example, 1/2, 3/4, 64/2, and so forth are all rational numbers. Represent rational numbers as two pointers to integers, one for the numerator and one for the denominator. Call the class Rational. Include a constructor with two arguments that can be used to set the member variables of an object to any legitimate values. Also, include a constructor that has only a single parameter of type int; call this single parameter whole_number and define the constructor so that the object will be initialized to the rational number whole_number/l. Also, include a default constructor that initializes an object to 0 (that is, to 0/1). Write input and output functions. Numbers are to be output in the form 1/2, 15/32, 300/401, and so forth. Note that the numerator, the denominator, or both may contain a minus sign, so -1/2, 15/- 32, and - 300/- 401 are also possible inputs. Overload all of the following operators so that they correctly apply to the type Rational: =, , >=, +, -, *, and/
