cpp面向對象編程

如下圖，先建好文件， 這裡用的是Visual studio 2010

當然也可以用eclipse for cpp,如下圖：

AbstractShape.h

 ABSTRACTSHAPE_H_


    
    AbstractShape(
    
      calcArea()= /* ABSTRACTSHAPE_H_ */

AbstractShape.cpp

#include ->edge = ->

Triangle.h

#include  TRIANGLE_H_


 Triangle: 
    
    Triangle( bottom, 
     /* TRIANGLE_H_ */

Triangle.cpp

#include  bottom, ->bottom =->height = ->bottom * ->height / 

Rectangle.h

#include  RECTANGLE_H_


 Rectangle: 
    
    Rectangle( bottom, 
     /* RECTANGLE_H_ */

Rectangle.cpp

#include  bottom, ->bottom =->height = ->bottom * ->

Main.cpp

#include <iostream>
 = Triangle(, << triangle.getEdge() <<<< triangle.calcArea() <<= Rectangle(, << rectangle.getEdge() <<<< rectangle.calcArea() << 

編譯運行，運行結果：
