Question

I only need the "functions" NOT the header file nor the main implementation file JUST the implementations for the functions

Please help, if its difficult to do the complete program I would appreciate if you could do as much functions as you can especially for the derived class.
I am a beginer so I am only using classes and pointers while implementing everything using simple c++ commands
thank you in advanced

Design and implement two C++ classes to provide matrix operations (addition, subtraction, multiplication) as Many mathematical functions and simple games use a two-dimensional grid that can be Source: www.xkcd.com implemented with a two-dimensional array Create a grid class to provide a basic grid functionality grid - rows: int -cols: int -**intGrid: int MAX ROW 5000: static constexpr int MAX COL 5000: static constexpr int +grid(int-0, int-0) +grid() +setCell(int, int, int): void +getCell(int, int) const: int +printGrid() const: void +setSize(int, int): void +getRows () const: int +getCols() const: int The following are more detailed descriptions of the required functions The grid0 function is the constructor. The constructor should set the rows and cols class variables and dynamically create the two-dimensional array based on the provided input (row, cols). The arguments are the number of rows and columns in the grid. The constructor should ensure that the provided grid size is within the defined parameters (0 MAX_ROW, 0-MAX COL) inclusive. If not, an error message should be displayed and no board created and the class variables initialized appropriately. The constructor should dynamically create the board and initialize all cells to 0. Note, since a 1 by 1 grid is a scaler, a 1 by 1 grid is an error. The "grid() function is the destructor that should delete the dynamically allocated array. The setCell(int, int, int) should set the given cell, row and column, to the provided value. The arguments are the row, column, and new value (in that order). If an invalid location is provided, the function should display an error message. The getCell(int, int) should return the given content of the given row and column. The arguments are the row, column (in that order). If an invalid location is provided, the function should display an error message. The printGrid) function should print the contents of the grid including a leading and trailing '". Refer to the example output for a formatting example. The setSize(int, int) function should set the size matrix to the passed size (rows, columns). The function should ensure that the provided grid size is within the defined parameters (MAX_ROW and MAX_COL) inclusive. Note, while the constructor should allow a (0,0) matrix, the set size should not allow both rows and columns to be 0. If the size is incorrect, an error message should be displayed and the class variables not altered e size is correct, and a matrix already exists, it must be dynamically deleted before the new sized matrix is dynamically created. After the new matrix is created, the function should set the rows and cols class variables and initialize all cells to 0. Note, since a 1 by 1 grid is a scaler, a 1 by 1 grid is an error. The getRows0 and getCols) functions should return the applicable class variables. The matrix type class, based on grid class, should provide the matrix operations.

Question: Implement C++ Code to do multiple matrix operation (like us addition, subtraction, multiplication)

Answer:

(a) Implement two C++ class to do addition of two multi-dimensional Matrix

-- Need to introduce a 'source file' cpp file to do these operations.

Below is the sample simple C++ cpp code

create file 'add_two_matrix.cpp' and write the below code

$vim add_two_matrix.cpp

/*-- START OF CODE --*/

#include<iostream.h> //include needed header files

//declare 2nd matrix class

class matrix_2;

//define 1st matrix class

class matrix_1

{

//define member variables

//define two dimensional matrix with size of 10*10

int a[10][10];

//define m.n as the range - until which matrix to be loaded

int m,n;

//define member functions

public:

//define member function to get values from user

void getValuesForMatrix1();

//define memeber function to load selected values from user

void putValuesIntoMatrix1();

//friend function to do matrix add,matrix substract,matrix multiply

friend void add_matrix(matrix_1,matrix_2);

friend void substract_matrix(matrix_1,matrix_2);

friend void multiply_matrix(matrix_1,matrix_2);  

};

void matrix_1::getValuesForMatrix1()

{

int i,j;

cout<<"Matrix 1 :\n"

}

void matrix_1::putValuesIntoMatrix1()

{

int i,j;

cout<<"Matrix 1 :\n"

for(i=0:i<m;i++)

{

for(j=0;j<n;j++)

{

cout<<a[i][j]<<" ";

}

cout<<endl;

}

//define 2nd matrix class

class matrix_2

{

//define member variables

//define two dimensional matrix with size of 10*10

int b[10][10];

//define m.n as the range - until which matrix to be loaded

//define member function to get values from user
