We know that the virtual function in C + + can be used to implement polymorphism. Inheriting classes can implement their own functionality to override the base class. For example, the following code#include #includestring>using

#include #include using namespace std;class person{string name; bool gender; int age; Person *lover;public:person (const char *n= "nameless", bool g=true); void growup (int years); void Show ();}; Person::P Erson (const char *n,bool g/*=

#include //void Show (char *p[]);voidShowChars[][Ten]);intMain () {Chars[3][Ten]={"123","ABC","XYZ"}; Char*p[Ten]; //array of pointers to iterate overp[1] = s[1]; Char(*PS) []; PS=s;}#include #includestring.h>#defineSIZE 80#defineLMT
