Create a class, using separate files, named DynamicGrades. (2 points) This class has three data members: an int that represents the student id, an int that stores the number of grades, and a pointer to int that represents a dynamic array the size specified by the previous data member. (2 points) Create at least one constructor that allocates the appropriate dynamic array. Also create a destructor to free the dynamic array. (2 points) Create at a mutator function that takes three parameters: an int that represents the id of the student, an int that represents the index location for the grade, an int that represents the grade for the location specified. (2 points) Create an accessor function that takes two parameters: an int that represents the id of the student, and int that represents th index location for the grade. The function returns the grade for the location specified. (1 point) In main() , create a regular object and a dynamic object. Exercise all constructors and functions. Provide all source code, each file containing a comment with your name, course code and date. Also provide a screenshot with a sample run (1 point). Submit source code and screenshot together in a zip file.

Explanation:

#include <iostream>

using namespace std;

//DynamicGrades.h

class DynamicGrades

{

public:

DynamicGrades(int size);

~DynamicGrades();

void mutate(int studentId, int index, int grade);

int getGrade(int studentId, int index);

private:

int m_studentId;

int m_noofGrades;

int* m_dynamicArr;

};

//DynamicGrades.cpp

#include "DynamicGrades.h"

DynamicGrades::DynamicGrades(int size)

{

m_noofGrades = size;

m_dynamicArr = new int[m_noofGrades] {0};

}

DynamicGrades::~DynamicGrades()

{

if(nullptr != m_dynamicArr)

delete[] m_dynamicArr;

}

void DynamicGrades::mutate(int studentId, int index, int grade)

{

m_studentId = studentId;

if (index < m_noofGrades)

m_dynamicArr[index] = grade;

}

int DynamicGrades::getGrade(int studentId, int index)

{

if (index >= m_noofGrades)

return -1;

return m_dynamicArr[index];

}

//Main.cpp

#include "DynamicGrades.h"

int main()

{

DynamicGrades* grade = new DynamicGrades(5);

DynamicGrades grade2(10);

for (int i = 0;i < 5;++i)

{

grade->mutate(2, i, i + 1);

}

for (int i = 0; i < 10; i++)

{

grade2.mutate(3, i, i + 1);

}

cout << "Grades are " << endl;

for (int i = 0;i < 5;++i)

{

cout << grade->getGrade(2, i) <<" ";

}

cout << endl;

for (int i = 0; i < 10; i++)

{

cout << grade2.getGrade(3, i) << " ";

}

}

the correct answer is "part of speech" if the portion used is "verb, noun" there is another question similar to this with the same question but different portion. the other portion is "hand write" and the correct component for that question is "antonym".

hope this . : )
