What is your name? (if valid name then continue to question 2)

What is your email? (if not valid then ask this question again, if valid then next question)

How old are you? (again, if invalid then ask again, if valid then next.

CPP

Task: You are to write a class called Monomial, using filenames monomial.h and monomial.cpp, that will allow creation and handling of univariate monomials, as described below.

Monomial Description

Each monomial object has following properties:

• Each monomial has a coefficient and a power.
• Monomial power is always positive.
• Monomial power is always integer.
• Monomials cannot be added if they have different powers

Class Details

1. The single constructor for the Monomial class should have 2 parameters: an floating point coefficient value (optional, with a default value of 1.0); and an integer power value (optional, with a default value of 1). If the power value is less then 1, set the power to 1. The class will need to provide internal storage for any member data that must be kept track of.

2. There should be member functions GetCoefficient, and GetPower, which will return the monomial’s coefficient value, and monomial’s power value, respectively. The GetPower method should return integer results. The GetCoefficient function should return its result as a float.

3. There should be member functions SetPower, which will set the monomial’s power to the arbitrary positive value. If the parameter is not positive then set the power to the default value 1.

4. There should be member function Add, which adds the one monomial to the other. The parameter of this member function need to be a constant reference to the other monomial object. The monomials can only be added if they have the same power, otherwise error message must be printed. The result of the addition is saved in the caller object.

5. There should be two member functions Multiply (overrides), which each allow to multiply a monomial to a number and to another monomial. The first member function need to accept floating point parameter that is used to perform multiplication of the real number on the the monomial object. The second member function need to accept a constant reference to the other monomial object. Use monomials to coefficients and powers to perform their multiplication. The result of the multiplication is saved in the caller object.

6. There should be a member function called Exponent that perform exponentiation (raise to power) of the monomial to the specified power value. You only can raise monomial to the positive power, if the power parameter is not positive print error message. The result of the exponentiation is saved in the caller object.

7. A sample driver program (called monomial-driver.cpp) is provided. It uses objects of type Monomial and illustrates sample usage of the member functions.

8. Your class declaration and definition files must work with my main program from the test driver, as-is (do not change my program to make your code work!). You are encouraged to write your own driver routines to further test the functionality of your class, as well. Most questions about the required behavior of the class can be determined by carefully examining my driver program and the sample execution. Keep in mind, this is just a sample. Your class must meet the requirements listed above in the specification - not just satisfy this driver program. (For instance, I haven’t tested every illegal fill character in this driver program - I’ve just shown a sample). Your class will be tested with a larger set of calls than this driver program represents.

General Requirements

• No global variables, other than constants!
• All member data of your class must be private
• You can only use the <iostream> library for output. !!! No other libraries are allowed !!!.
• When you write source code, it should be readable and well-documented.
• Here are some general notes on style guidelines
• Your monomial.h file should contain the class declaration only. The monomial.cpp file should contain the member function definitions.

Test Driver:

//
// driver.cpp -- driver program to demonstrate the behavior of
//               the Monomial class

#include <iostream>
#include "monomial.h"

using namespace std;

int main()
{
    // create some monomial: x, 2x, 12.5x³, -3xâ¶
    Monomial m1, m2( 2.0 ), m3( 12.5, -1 ), m4( -3.0 , 6);
    // display monomial
    cout << "Monomial `m1` has the coefficient " << m1.GetCoefficient()
         << " and power " << m1.GetPower() << ": ";
    m1.Print();
    cout << "Monomial `m2` has the coefficient " << m2.GetCoefficient()
         << " and power " << m2.GetPower() << ": ";
    m2.Print();
    cout << "Monomial `m3` has the coefficient " << m3.GetCoefficient()
         << " and power " << m3.GetPower() << ": ";
    m3.Print();
    cout << "Monomial `m4` has the coefficient " << m4.GetCoefficient()
         << " and power " << m4.GetPower() << ": ";
    m4.Print();

    // Change monomial power
    cout << "Monomial `m3` power wasn't changed: ";
    m3.SetPower(-1);
    m3.Print();
    cout << "Monomial `m3` power was changed: ";
    m3.SetPower(3);
    m3.Print();

    // can add monomials with the same powers
    cout << "Monomial addition" << endl;
    m1.Add(m2);
    cout << "x + 2x = ";
    m1.Print();
    // cannot add monomials with different powers
    cout << "x³ + 12.5x³ = ";
    m2.Add(m3);

    // can multiply monomial to a number
    cout << "Monomial multiplication by a number" << endl;
    m2.Multiply(2.5);
    cout << "2x * 2.5 = ";
    m2.Print();

    // can multiply monomials
    cout << "Monomial multiplication by a monomial" << endl;
    m3.Multiply(m4);
    cout << "12.5x³ * -3xⶠ= ";
    m3.Print();

    // can raise monomial to the power
    cout << "Monomial exponentiation" << endl;
    m4.Exponent(3);
    cout << "(-3xâ¶)³ = "; // -27x^18
    m4.Print();
    cout << "(3x)â° = "; // -27x^18
    m1.Exponent(-10);

    return 0;
}

Test Driver Output

Monomial `m1` has the coefficient 1 and power 1: 1x^1
Monomial `m2` has the coefficient 2 and power 1: 2x^1
Monomial `m3` has the coefficient 12.5 and power 1: 12.5x^1

On Lab 10 you did Chapter 8’s Programming Exercise 13, using the name Lab10TestScores and assuming that the class has ten students and five tests. Now let’s rewrite it to use dynamic arrays so that it will work for any number of students and any number of tests. Call this new program Lab11TestScores. Modify the program so that it asks the user to enter the number of students and the number of tests before it reads the data from the file named Lab11ScoresData.txt. (Two data files, Lab11ScoresData_5_3.txt and Lab11ScoresData_11_6.txt, are provided so you can use to test your program.). Let me know if you have questions. #include #include using namespace std; void readFile(string names[10], int scores[][5]) { ifstream in("Lab10ScoresData.txt"); for (int i = 0; i < 10; i++) { in >> names[i] >> scores[i][0] >> scores[i][1] >> scores[i][2] >> scores[i][3] >> scores[i][4]; } } void average(int scores[][5], float avg[], char grade[]) { int total; for (int i = 0; i < 10; i++) { total = 0; for (int j = 0; j < 5; j++) total += scores[i][j]; avg[i] = (float)total / (float)5; } for (int i = 0; i < 10; i++) { if (avg[i] >= 90) grade[i] = 'A'; if (avg[i] < 90 && avg[i] >= 80) grade[i] = 'B'; if (avg[i] < 80 && avg[i] >= 70) grade[i] = 'C'; if (avg[i] < 70 && avg[i] >= 60) grade[i] = 'D'; if (avg[i] < 60 && avg[i] >= 50) grade[i] = 'E'; if (avg[i] < 50) grade[i] = 'F'; } } void sortByName(string names[], float avg[], char grade[]) { for (int i = 0; i < 9; i++) { for (int j = i + 1; j < 10; j++) { if (names[i] > names[j]) { string n = names[i]; names[i] = names[j]; names[j] = n; float a = avg[i]; avg[i] = avg[j]; avg[j] = a; char g = grade[i]; grade[i] = grade[j]; grade[j] = g; } } } } void output(string names[], float avg[], char grade[]) { cout << "Name\tAverage\tGrade\n"; for (int i = 0; i < 10; i++) { cout << names[i] << "\t" << avg[i] << "\t" << grade[i] << endl; } } void countGrade(char grade[]) { int a = 0, b = 0, c = 0, d = 0, e = 0, f = 0; cout << "\n\nGrade\tCount\n"; for (int i = 0; i < 10; i++) { if (grade[i] == 'A') a++; if (grade[i] == 'B') b++; if (grade[i] == 'C') c++; if (grade[i] == 'D') d++; if (grade[i] == 'E') e++; if (grade[i] == 'F') f++; } cout << "A\t" << a << endl; cout << "B\t" << b << endl; cout << "C\t" << c << endl; cout << "D\t" << d << endl; cout << "E\t" << e << endl; cout << "F\t" << f << endl; } int main() { string names[10]; int scores[10][5]; float avg[10]; char grade[10]; readFile(names, scores); average(scores, avg, grade); sortByName(names, avg, grade); output(names, avg, grade); countGrade(grade); system(" pause "); return 0; }
