葫芦听她说的逗乐，不禁微笑起来。If I were to implement a pizza ordering system, I would definitely write the code like this, because this kind of code can be written subconsciously without consuming our brains. However, take a closer look at this code: the purpose of this method is to order pizza. However, the code for ordering pizza also needs knowledge about the production of pizza. This method must know all pizza. Worse still, if the types of pizza are to be expanded or pizza with poor sales volume are to be deleted in the future, then the code for ordering pizza will be modified. It looks very bad and should be revised. Our first step must be to separate the code for producing Pizza from the code for ordering pizza, because you should not let the code for ordering Pizza know the logic for producing pizza, but should hand over the logic for producing Pizza to a special type. In this way, we can cope with future changes-if we want to add or delete pizza, we can directly modify the producer of pizza without affecting the logic of ordering pizza.Prospects for Deliberate Practice//304Synchronous non-blocking I/0　　参赛家庭住进了电视台特别设计的「悭钱屋」，屋内设备齐全，可是每一个项目都要收费。七天的时限，各人出尽所有悭钱的伎俩，到处试食医肚、到化妆品柜台化妆、到公众浴室洗澡。受尽折腾之下，有人偷偷花钱、有人爱子心切甘愿牺牲、有人年幼无知、有人紧守游戏规则，人性尽现。在游戏中，Diana 认识了韦大汉的另一面；徐少侠与千嬅从识英 雄重英雄进一步有所发展，可是事情却被节目监制利用，最后韦家排除万难，成为「悭钱家族」游戏的优胜家庭，不过司仪却宣布要耻夺他们的参赛资格……Article 6 Safe Speed
