write a C++ program for this,

if it is still not clear, please indicate which part. Thanks

This is what I got so far:

#include #include #include #include using namespace std;

const int MAX_ROWS = 15; const int MAX_COLS = 15; const int Larg_Num = 3;

class Matrix { // Represents a varying-size matrix that can be input from a file public: Matrix() {} Matrix(int, int, int); // Constructor that initializes matrix size and sets all valid elements to given initial value void transpose(Matrix&); // Changes passed matrix to transpose of current object matrix void showDiagonal() const; // Displays diagonal of a square matrix void uppertriangularmatrix(Matrix&); // ZERO out lower traiangilar matrix. void findlarge(int [Larg_Num][3]) const;

private: int rows; int cols; int mat[MAX_ROWS][MAX_COLS]; friend ostream& operator> (istream&, Matrix&); friend Matrix& operator*= (Matrix&, const Matrix&); };

//*this = prod;

//return *this;

int main() { Matrix m; Matrix t; int largest[Larg_Num][3]; ifstream infile("matrix_chap9_5.txt", ios::in); infile >>m; m.transpose(t); t *= m; cout

Matrix::Matrix(int i, int j, int z) { rows = i; cols = j; for (i = 0; i

void Matrix::transpose(Matrix &t) { t.rows = cols t.cols = rows for (int i = 0; i

void Matrix::showDiagonal() const { if (rows == cols) { for (int i = 0; i

void Matrix::findlarge(int large[Larg_Num][3]) const { for (i = 0; i large[0][0]) for (int k = ; mat[i][j] >= large[k][0]; ++k) { large[k][0] = large[k + 1][0]; large[k][1] = large[k + 1][1]; large[k][2] = large[k + 1][2]; } large[--k][0] = mat[i][j]; large[k][1] = i; large[k][2] = j; } } }

ostream & operator

istream & operator >> (istream &is, Matrix &m) { for (int i = 0; i > m.mat[i][j]; } } return is; }

Matrix & operator*=(Matrix &, const Matrix &) { int val, i, j, k;

Matrix prod;

if (cols != m2.rows) {

cout

prod.rows = 0; prod.cols = 0;

} else {

prod.rows = rows; prod.cols = m2.cols;

for (i = 0; i

for (j = 0; j

val = 0;

for (k = 0; k

val += mat[i][k] * m2.mat[k][j];

prod.mat[i][j] = val; }
