The difference between 7.vector and list (this is often asked)Vectors and arrays are similar, have a contiguous memory space, and the starting address is constant, so that the random read is very efficient (that is, all of our [] operators), because

Original articles, without the permission of bloggers to prohibit reprint.C + + classes can make forward declarations. However, classes that simply do not define a forward declaration are incomplete, and such classes can only be used to define
