For this assignment you will be building on your Fraction class. However, the changes will be significant, so I would recommend starting from scratch and using your previous version as a resource when appropriate. For this assignment, we will correctly handle Fractions that are negative, improper (larger numerator than denominator), or whole numbers (denominator of 1). Your class should support the following operations on Fraction objects: Construction of a Fraction from two, one, or zero integer arguments. If two arguments, they are assumed to be the numerator and denominator, just one is assumed to be a whole number, and zero arguments creates a zero Fraction. Use default parameters so that you only need a single function to implement all three of these constructors. You should check to make sure that the denominator is not set to 0. The easiest way to do this is to use an assert statement: assert(inDenominator != 0); You can put this statement at the top of your constructor. Note that the variable in the assert() is the incoming parameter, not the data member. In order to use assert(), you must #include Printing a Fraction to a stream with an overloaded insertion (<<) operator. The Fraction should be printed in reduced form (not 3/6 but 1/2). Whole numbers should print without a denominator (e.g. not 3/1 but just 3). Improper Fractions should be printed as a mixed number with a + sign between the two parts (2+1/2). Negative Fractions should be printed with a leading minus sign. Reading a Fraction from a stream using an overloaded extraction (>>) operator. You should be able to read any of the formats described above (mixed number, negative, whole numbers). You may assume that there are no spaces or formatting errors in the Fractions that you read. This means, for example, that in a mixed number only the whole number (not the numerator or denominator) may be negative, and that in a fraction with no whole number part only the numerator (not the denominator) may be negative. Note: You may need to exceed 15 lines for this function. My solution is about 20 lines long. All six of the relational operators (<, <=, >, >=, ==, !=) should be supported. They should be able to compare Fractions to other Fractions as well as Fractions to integers. Either Fractions or integers can appear on either side of the binary comparison operator. You should only use one function for each operator. The four basic arithmetic operations (+, -, *, /) should be supported. Again, they should allow Fractions to be combined with other Fractions, as well as with integers. Either Fractions or integers can appear on either side of the binary operator. Only use one function for each operator. Note that no special handling is needed to handle the case of dividing by a Fraction that is equal to 0. If the client attempts to do this, they will get a runtime error, which is the same behavior they would expect if they tried to divide by an int or double that was equal to 0. The shorthand arithmetic assignment operators (+=, -=, *=, /=) should also be implemented. Fractions can appear on the left-hand side, and Fractions or integers on the right-hand side. Only use one function for each operator. The increment and decrement (++, --) operators should be supported in both prefix and postfix form for Fractions. To increment or decrement a Fraction means to add or subtract (respectively) one (1).
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

For this assignment, we will correctly handle Fractions that are negative, improper (larger numerator than denominator), or whole numbers (denominator of 1).
Your class should support the following operations on Fraction objects:

If two arguments, they are assumed to be the numerator and denominator, just one is assumed to be a whole number, and zero arguments creates a zero Fraction. Use default parameters so that you only need a single function to implement all three of these constructors.
You should check to make sure that the denominator is not set to 0. The easiest way to do this is to use an assert statement: assert(inDenominator != 0); You can put this statement at the top of your constructor. Note that the variable in the assert() is the incoming parameter, not the data member. In order to use assert(), you must #include <cassert> - Printing a Fraction to a stream with an overloaded insertion (<<) operator. The Fraction should be printed in reduced form (not 3/6 but 1/2).
