B$.$ Create a new class called Term to represent a term in a polynomial such as $2x^4$ or $9x^2.$

The Term class should have the following capabilities:

It should have two private data members of type int called coefficient and exponent.

It should have exactly one constructor with $2$ parameters $($the first parameter for a coefficient value and the

second parameter for an exponent value$)$ that enables an object of Term class to be initialized when it is

declared. The constructor should contain default values which would initialize coefficient and exponent to $0s$ if

no values are provided in a constructor call.

The class should have getter and setter methods for coefficient and exponent: setCoefficiend, setExponent,

getCoefficient, getExponent.

Overload the addition, subtraction, and multiplication operators for this class: operatort, operator$-,$

operator$*.$ The overloaded operators should be implemented as member functions of the class.

For the purpose of this assignment:

Adding Terms can only be done if the exponents are the same: $a{x}^n+b{x}^a=(a+b)x^n$

Subtracting Terms can only be done if the exponents are the same: $a{x}^n-b{x}^n=(a-b)x^n$

If the exponents aren't the same, the addition and subtraction operators should return a Term with $0$

as the coefficient and $0$ as the exponent.

Multiplication: $a{x}^n**b{x}^n=(a^{**}b)x^{(n+a)}$

Overload the binary stream extraction and stream insertion operators $($see how to do it in section $18\mathrm{.}5$ of the

textbook$).$ Declare stream extraction and stream insertion operators as friends of the class. Stream extraction

operator should allow to input Term objects in the following customary format:

$2x^{4}or9x^2$

where ${?}^{?}$ is used to indicate the exponent $($instead of a superscript$).$

Stream insertion operator should allow to output Term object in the same customary format, e$.$g$.$

$2x^{4}or9x^2$

$($coefficient followed by $x^{?},$ followed by exponent$).$

C$.$ Separate interface and implementation for Term class. Create two files: Term.h $($class definition containing

function prototypes$)$ and Term.cpp $($implementations of member functions and overloaded stream insertion and

stream extraction operators$).$ Make sure to use include guard in Term.h$.$

D$.$ Write a test program named Labl$0.$cpp that will test all the functions of Term class and overloaded stream

insertion and stream extraction operators.

Your test program should contain statements such as:

Note that for the addition and subtraction operators you need to have at least $2$ tests for each: one test for the

terms with the same exponents and one test for the terms with different exponents.
