将std::map移植到C语言中,需要了解C语言中没有与std::map相同的容器。但是,可以使用结构体和链表等数据结构来实现类似的功能。 首先,需要定义一个键值对的结构体,如下所示: ```c ...
6.5.1 Insert Iterator (安插型迭代器) 迭代器适配器的第一个例子是insert iterator ,或称insertor 。它可以使算法以安插(insert)方式而非覆写(overwrite)方式运作。使用它可以解决算法的“目标空间不足”问题。是的,它会使目标区间的大写需要成长。 如果你对某个元素赋值(assign),会引发“对其所属集合的安插...

STLstd::mapwill not be implemented in CTL because maps only provide slight syntactic improvements over sets. STL variants of multi-sets and multi-maps will not be implemented because similar behaviour can be implemented as an amalgamation of asetandlst. ...
