C++ 中常用函数：类似数组，向量使用连续的存储位置来存储元素，这意味着可以通过对其元素的正向指针偏移来访问这些元素，访问效率与数组相同。
c++ vector 常用函数
Just like arrays, vectors use contiguous storage locations for their elements, which means that their elements can also be accessed using offsets on regular pointers to its elements, and just as efficiently as in arrays. But unlike arrays, their size can change dynamically, with their storage being handled automatically by the container.
vector也是一个数组但是它的占用的内存大小是动态变化的。当vector占用的内存满了之后，就要重新分配内存，并且赋值原来的所有元素，为了避免频繁的重新分配内存，迁移数据。vector实际分配的内存比你需要的内存多。
