设计模式：模板方法

#include class Abstract_Sport {
public:void template_method() {start();end();start();end();}virtual void start() = 0;virtual void end() = 0;
};class Concrete_BasketBall : public Abstract_Sport {void start() {std::cout << "BasketBall start" << std::endl;}void end() {std::cout << "BasketBall end" << std::endl;}
};class Concrete_FootBall : public Abstract_Sport {void start() {std::cout << "FootBall start" << std::endl;}void end() {std::cout << "FootBall end" << std::endl;}
};int main(int argc, char* argv[]) {std::cout << "---------" << std::endl;Abstract_Sport* p = new Concrete_BasketBall();p->template_method();p->start();p->end();delete p;p = NULL;std::cout << "---------" << std::endl;p = new Concrete_FootBall();p->template_method();p->start();p->end();delete p;p = NULL;return 0;
}

输出：

BasketBall start
BasketBall end
BasketBall start
BasketBall end
BasketBall start
BasketBall end

FootBall start
FootBall end
FootBall start
FootBall end
FootBall start
FootBall end
