将内容分配给正则表达式。
1%29分配other...flags()和mark_count()的值等于other.flags()和other.mark_count()打完电话后。
2%29分配other使用移动语义。flags()和mark_count()的值等于other.flags()和other.mark_count()在任务之前。打完电话后，other处于有效但未指定的状态。
3-7%29给正则表达式分配一个字符序列.。语法标志设置为f...mark_count()返回调用后结果子表达式中标记的子表达式的数目。
3%29指定一个以空结尾的字符串，该字符串由s...
4%29分配一个序列count字符，由s...
5%29分配字符串str...
6%29指定范围内的字符[first, last)...
7%29分配初始化程序列表中的字符。ilist...
