问题：如何遍历 “向量”和“数组”？
Vector VS Loop In a way,a vector as a data structure is closely related to a loop as a control structure. Traversing a vector(for the purpose of inspection,search, summation,etc.)is typically carried out with a single iterative construct. Just as the loop is a control structure for describing lengthy processes,so is a vector a data structure for representing lengthy lists of data items

问题：以下两者的区别何在？ 在书架中取一本书 在一桶纸杯中拿一个杯子 In many applications of vectors and arrays,we do not need the full power provided by INDICES Sometimes a list is used just to model a queue. 使用时的随意性：任意存取 使用时的受限性：头存尾取 代价更高的数组才能实现如此的随意性 代价较低的队列就能实现受限的存取
