ADT: RationalNumber

Define a class for rational numbers. A rational number is “ratio-nal” number, composed of two integers with division indicated.
The division is not carried out; it is only indicated, as in 1/2, 2/3, 15/32, 65/4, 16/5.
You should represent rational numbers by two values.
1. An integer named numerator displayed above a line or before a slash.
2. An integer named denominator displayed below or after that line.
Value should only be assigned to denominator if it is non-zero, 1 otherwise.
1. Provide the implementation of mutators for numerator and denominator data members of the class.
2. Provide the implementation of accessors for numerator and denominator data members of the class.
A principle of abstract data type construction is that constructors must be present to create objects with legal values. You should
provide constructors to make objects out of pairs of integer values;
1. A constructor that accepts Rational Number’s numerator and denominator as arguments and assigns them to the
appropriate member variables.
2. Since every integer is also a rational number, 2/1 or 17/1, you should provide a constructor with single integer parameter
that accept only the value of numerator as argument and assign it to the appropriate member variable.
3. Provide the implementation of following member functions and operators
1. write method to write rational numbers in the form 2/3 or 37/51 on the screen.
2. read method to input rational numbers in the form 2/3 or 37/51 from the keyboard.
3. Overload plus (+) binary operator to perform the addition of two rational numbers.
4. Overload minus (–) binary operator to perform the subtraction of two rational numbers and returns the result.
5. Overload multiply (*) binary operator to perform the multiplication of two rational numbers and returns the result.
6. Overload divide (/) binary operator to perform the division of two rational numbers and returns the result.
7. Overload less than (<) binary operator to perform the comparison of two rational numbers and returns the result.
8. Overload equal (==) binary operator to perform the comparison of two rational numbers and returns the result.
9. Overload minus (–) unary operator to convert a rational number into its negative form, if it is already not and returns the
result.
10. Overload logical not (!) unary operator to return true if the rational number is negative, false otherwise.
4. Once you have written the class, write main function and test its functionality by creating some objects of RationalNumber.
The formulas will be useful in defining functions:
a/b + c/d means (a*d + b*c) / (b*d)
a/b – c/d means (a*d – b*c) / (b*d)
(a/b) * (c/d) means (a*c) / (b*d)
(a/b) / (c/d) means (a*d) / (c*b)
–(a/b) means (–a/b)
(a/b) < (c/d) means (a*d) < (c*b)
(a/b) == (c/d) means (a*d) == (c*d)
Let any sign be carried by the numerator; keep the denominator positive.
