C++ HW5-2 for WallPower

寫一個C++程式，輸入兩個3X3 A、B矩陣所有元素值後，計算出矩陣AB相乘結果。

參考輸出如下圖。

#include <iostream>
using namespace std;
 
int main()
{
 int A[3][3], B[3][3];
 for (int i = 0; i < 3; i++)
  for (int j = 0; j < 3; j++)
  {
   cout << "請輸入矩陣A第" << i + 1 << "行第" << j + 1 << "列的元素：";
   cin >> A[i][j];
  }
 for (int i = 0; i < 3; i++)
  for (int j = 0; j < 3; j++)
  {
   cout << "請輸入矩陣B第" << i + 1 << "行第" << j + 1 << "列的元素：";
   cin >> B[i][j];
  }
 for (int i = 0; i < 3; i++)
 {
  for (int j = 0; j < 3; j++)
  {
   cout << A[i][0] * B[0][j] + A[i][1] * B[1][j] + A[i][2] * B[2][j] << " ";
  }
  cout << endl;
 }
 system("pause");
 return 0;
}
