Person class each person object contains id, name, phone, and vplate (implemented as a vector or set). vplate is a collection holding the person's vehicle plate numbers. this collection could include zero or more plate numbers. as an example, consider the following sample. person(222, "name222", "555-2222", { "ca222a", "ca222b" }) the object above represents a person whose id number is 222; her name and phone are "name222" and "555- 2222" respectively. in addition, this person owns two vehicles and their plate numbers are "ca222a" and "ca222b". from figure 1, we observe that the person class consists of private data members (pid, pname, pphone, and vplate), as well as public accessors, mutators, constructor(s) and objstring() function (used to represent as a string the contents of the object). the person class methods addplate(string platevalue) and deleteplate(string platevalue) are us
