之前我们在声明数组的时候,采用的是datatype array[len]的形式,数组在分配之后,不能调整大小,删除和插入数据时操作十分的繁琐,虽然可以采用链表,但是链表的操作更麻烦,我喜欢简单的方法。 与string类一样, 向量vector 同属于STL(Standard Template Library, 标准模板库)中的自定义的类, vector是一个封装了动态数组的...
Vector vs Array Working of both vector and array are mostly similar.. The major difference between vector and array is that we dont have to specify size in vector while in array we have to.. So my question is which of the following should be used and Why?? Which of the following have...

为了克服array必须事先宣告大小的不便,STL和.NET都有解决的方式,在STL的container当中,速度最快的就是std::vector,而.NET当中就是ArrayList,所以我想测试在同样的程序中,若使用unmanaged 的std::vector是否会比managed ArrayList快。 1 /* 2 (C) OOMusou 2006http://oomusou.cnblogs.com ...
