C++vector比较大小 C++vector⽐较⼤⼩ 写在前：vector 是可以直接进⾏⽐较。vector 默认提供的 operator< 内使⽤了std::lexicographical_compare 进⾏⽐较，operator> 则⾮operator<，依赖operator<实现。简单说，即⽐较两个vector上的，每个位置上的字母，当发现不同的且字典序⼩的，拥有该...

A const random-access iterator addressing the first element in the vector Class or to the location succeeding an empty vector. You should always compare the value returned with vector::cend or vector::end to ensure it is valid.Remarks
vector是种容器,类似数组一样,但它的size可以动态改变。 vector的元素在内存中连续排列,这一点跟数组一样。这意味着我们元素的索引将非常快,而且也可以通过指针的偏移来获取vector中的元素。 但连续排列也带来了弊端,当我们向vector中间插入一个数据时,整个vector的size变大,在内存中就需要重...
