在类中使用一维数组进行矩阵乘法

Question

在乘法函数中，有两个矩阵将数据存储在一个指针索引中，但是问题是这不会显示相同的结果，请检查我的代码，如果您使用的是主函数，则Matrix Matrix::Multiply(Matrix b)在代码中发现一些错误，请告诉我

#include <iostream>
using namespace std;
#include <stdlib.h>

// implement the functions : add, sub, mult, transpose
class Matrix {
public:
    Matrix(int row, int col);
    int GetData();
    Matrix Transpose();
    int Display();
    Matrix DisplayA(Matrix c);
    Matrix Add(Matrix b);
    Matrix Sub();
    Matrix Multiply(Matrix b);
    int CompareRowCol(Matrix b);

private:
    int rows, cols;
    //int Term[rows][cols];
    int *Term;//the add 2.6ress of a[i][j] = 0 + i * cols + j => Fig2.6
};

Matrix::Matrix(int row, int col) : rows(row), cols(col)
{
    Term = new int[rows * cols];
}

int Matrix::GetData() {
    int input_value;
    cout << "rows = " << rows << "  cols = " << cols << endl;
    for (int j = 0; j < rows * cols; j++)
    {
        cout << "term value = ";
        cin >> input_value;
        cout << " " << endl;
        Term[j] = input_value;
    }
    return 0;
}

Matrix Matrix::Transpose() {
    Matrix b(cols, rows);

    for (int i = 0; i < cols; i++)
    {
        for (int j = i; j < rows*cols; j=j+cols)
        {
            cout << Term[j]<<" ";
        }
        cout << endl;
    }
    return b;
}

Matrix Matrix::Multiply(Matrix b) {
    if (cols != b.rows) cout << "Incompatible matrices" << endl;

    Matrix c(rows, b.cols);
    for (int i = 0; i < rows; i++)

            {
                sum = sum + Term[i*cols+k] * Term[k*b.cols + j];
                c.Term[i*b.cols + j] = sum;
            }
        }
    }

    for (int i = 0; i < rows*b.cols; i++)
    {
        cout << c.Term[i] << "\t";
    }

    return c;
}

int Matrix::CompareRowCol(Matrix b) {
    if (cols != b.rows) return 1;
    else return 0;
}

int Matrix::Display() {
    int n;

    n = rows * cols;
    for (int i = 0; i < rows; i++)
    {
        cout << endl;

        for (int j = 0; j < cols; j++)
            cout << Term[i*cols + j] << " ";
    }
    cout << endl;

            cout << c.Term[i*cols + j] << " ";
    }
    cout << endl;

    return c;
}

int main()
{
    Matrix a(2, 3);
    Matrix b(3, 4);
    Matrix c(2, 4);

    cout << "Enter first matrix: " << endl;
