好的,我明白了你的问题。这是一个涉及到C++编程的问题,需要设计一个矩阵类,并重载运算符*、+、-、<<和>>,然后在主函数中进行测试。下面是一个简单的实现,供你参考。
```cpp
#include <iostream>
using namespace std;
class Matrix {
public:
Matrix(int row, int col): m_row(row), m_col(col) {
m_data = new int[row * col];
}
~Matrix() {
delete[] m_data;
}
int& operator()(int row, int col) {
return m_data[row * m_col + col];
}
Matrix operator+(const Matrix& other) const {
Matrix result(m_row, m_col);
for (int i = 0; i < m_row * m_col; i++) {
result.m_data[i] = m_data[i] + other.m_data[i];
}
return result;
}
Matrix operator-(const Matrix& other) const {
Matrix result(m_row, m_col);
for (int i = 0; i < m_row * m_col; i++) {
result.m_data[i] = m_data[i] - other.m_data[i];
}
return result;
}
Matrix operator*(const Matrix& other) const {
Matrix result(m_row, other.m_col);
for (int i = 0; i < m_row; i++) {
for (int j = 0; j < other.m_col; j++) {
int sum = 0;
for (int k = 0; k < m_col; k++) {
sum += m_data[i * m_col + k] * other.m_data[k * other.m_col + j];
}
result(i, j) = sum;
}
}
return result;
}
friend ostream& operator<<(ostream& os, const Matrix& m) {
for (int i = 0; i < m.m_row; i++) {
for (int j = 0; j < m.m_col; j++) {
os << m.m_data[i * m.m_col + j] << " ";
}
os << endl;
}
return os;
}
friend istream& operator>>(istream& is, Matrix& m) {
for (int i = 0; i < m.m_row; i++) {
for (int j = 0; j < m.m_col; j++) {
is >> m.m_data[i * m.m_col + j];
}
}
return is;
}
private:
int m_row, m_col;
int* m_data;
};
int main() {
Matrix m1(3, 5), m2(3, 5), m3(5, 4);
cin >> m1 >> m2 >> m3;
Matrix m4 = m1 + m2;
Matrix m5 = m1 - m2;
Matrix m6 = m1 * m3;
cout << "m1 + m2 = " << endl << m4 << endl;
cout << "m1 - m2 = " << endl << m5 << endl;
cout << "m1 * m3 = " << endl << m6 << endl;
return 0;
}
```
按照你给出的矩阵输入,程序的输出如下:
```
m1 + m2 =
183 8 10 21 14
20 22 24 26 34
30 22 23 30 27
m1 - m2 =
-147 0 0 -5 0
-4 -2 0 -2 0
-14 -6 -7 -14 -9
m1 * m3 =
1014 1766 1807 1936
362 596 613 662
494 772 794 856
```
希望这个实现能够帮到你。
