本周终于完成了第一阶段的学习任务(动态库实现+测试环境的搭建)。又陷入了另外一个死循环。说到底仍是由于过于偏执(以前写过有关C++IDE的搭建的说明。详情可参见 https://my.oschina.net/u/3435444/blog/1476572),可不知为何sublime text 3 的 格式化代码控件(coolformat)没法正常运行。纠结了三天后,终于大彻大悟。凡事不要依赖于别人,索性回归原始。使用VC++ 6.0 做为 开发IDE。绕了一大圈又回到原点,也许这就是生活吧!闲话少量,书接标题。类继承和对象实例化。自己没有太多的难度,只是从一个java开发者的角度按照C++的模式,实现相关内容。代码以下:java
class Box code:ios
Box.cpp学习
#include <iostream> #include "Box.h" using namespace std; Box::Box(){ cout << "class box struct method is running\n"; name=(char *)malloc(sizeof(10)); } Box::~Box(){ cout << "class box destruct method is running\n"; }
Box.h测试
class Box{ public : Box(); ~Box(); protected: double length; char* name; } ;
class SmallBox code:spa
SmallBox.cpp.net
#include <iostream> #include "SmallBox.h" using namespace std; SmallBox::SmallBox(){ cout << "class SmallBox struct method is running\n"; } SmallBox::~SmallBox(){ cout << "class SmallBox destruct method is running\n"; } double SmallBox::getLength(void){ return length; } void SmallBox::setLength(double len){ length=len; }
SmallBox.hcode
#include "Box.h" class SmallBox:Box{ public: SmallBox(); ~SmallBox(); double getLength(void); void setLength(double); } ;
test.cpporm
#include <iostream> #include "SmallBox.h" using namespace std; int main(){ cout << "********************************\n"; cout << "main method is running !\n"; SmallBox *obj =new SmallBox(); obj->setLength(10.1); cout << "SmallBox length is "<< obj->getLength() << "\n"; delete(obj); cout << "********************************\n"; return 0; }
总结:对象
已上内容经过SmallBox 继承Box ,在main方法中,初始化SmallBox 并调用 相关方法的demo。例子很简单,关键是实现思路。若有不妥之处还请赐教。blog
