c + +繪製矩形位置

Question

我有我的課：

class Rectangle : public TwoDim 
{ 
public: 
    void fun() {}; 
    void printShape(); 
    Rectangle(int x1, int y1, int height1, int width1) 
    { 
     x = x1; 
     y = y1; 
     height = height1; 
     width = width1; 

    } 

}; 

而且功能打印：

void Rectangle::printShape() 
{ 
    { 

     cout << "+"; 
     for (int i = 0; i < width - 2; i++) 
     { 
      cout << "-"; 
     } 
     cout << "+\n"; 

     for (int i = 0; i < height - 2; i++) 
     { 
      cout << "|"; 
      for (int j = 0; j < +width - 2; j++) 
      { 
       cout << " "; 
      } 
      cout << "|\n"; 
     } 

     cout << "+"; 
     for (int i = 0; i < width - 2; i++) 
     { 
      cout << "-"; 
     } 
     cout << "+\n"; 
    } 

} 

如何更改我的功能，這樣我會畫從點開始的矩形(x, y)？

非常感謝

我會用實際印刷之前輸出ystd::endl s，然後有效地打印每一行之前輸出x" "開始。
