小学生日皮照片

板栗等人回来后，又参加家宴。翘儿握着拳头，也跟着点头，她心理还是有些没底的，可丈夫都铺到这步了，自己不能输。到最后，杨长帆尚留了一分仁义。中原靠西面地方全部被越军占领，东部狭小的一部分又被梁国分走了，可以说汉国现在是国土最为狭小。娘可知这医学院就是这一方百姓捐银建成的？遂把医学院的历史数说了一遍，又历数了方家等官宦人家都捐了多少银子，娘想想，父亲好歹也是朝廷三品官员，娘又叫医学院的人治好了病，却舍不得几个银子，叫旁人看了如何说？前面的话倒还罢了，只这后一句话听得黄夫人动容，当即就要捐四千两——无论如何也不能丢了她家老爷的脸面。Self-imported SFCIn real life, China's income tax is divided into enterprise income tax, foreign-invested enterprises or foreign-invested enterprises income tax and personal income tax. For these three types of income tax, each is calculated in a different way. Personal income tax has a personal income tax calculation method, while enterprise income tax has its corresponding calculation method. If we do not adopt the policy mode to realize such a requirement, we will define an income tax class, which has an attribute to identify the type of income tax and a CalculateTax () method to calculate the tax. In this method, we need to judge the tax type and calculate the income tax for different tax types through if-else statements. Such an implementation can indeed solve this scenario, but such a design is not conducive to expansion. If the system needs to add an income tax in the later period, it has to go back and modify the CalculateTax method to add an additional judgment statement, which clearly violates the principle of "open-closed". At this time, we can consider using the strategic mode to solve this problem. Since the tax method is the changing part of this scenario, we can naturally think of abstracting the tax method at this time, which is also the essence of the implementation of the strategic mode.
