1、一般而言,没有任何erase()、clear()、pop_back() 、pop_front()或swap()函数会抛出异常。也没有任何被返回的迭代器的copy构造函数assignment操作符会抛出异常。 2、对于所有以节点为构造基础(node-based)的容器如list、set 、multiset、map、multimap,以及无序容器,如果

C把文件看做是一系列连续的字节,每个字节都被单独读取,这与UNIX环境的文件结构相对应。由于其他环境中可能无法完全对应这个模型,C提供两种文件模式:文本模式和二进制模式。 所有文件的内容都以二进制形式(0或1)存储。但是,如果文件最初使用二进制编码的字符(例如ASCII或Unicode)表示文本(就像C字符串一样),该文件就...
