Define a class called Rational. A rational number is a number that can be represented as the quotient of two integers (i. e., fractions). For example, 1/2, 3/4, 64/2, and so forth are all rational numbers (By 1/2 and so on we mean the everyday fraction, not the integer division this expression would produce in a C program.) Your class should represent rational numbers as two values of type int, one for the numerator and one for the denominator. The class should include the following three constructors:
