c ++ realize address book management system (console version)

This program is suitable for beginners c ++, for c ++ basics, related to the variable structure is defined using the definition of an array using pointer definitions used and so on.

Run after the results are as follows:

Code:

#include <the iostream> 
#include < String >
 the using  namespace STD;
 #define MAX 1000 // define a maximum capacity of 1000 contacts 
@ contact structure 
struct Person
{
    string name;
    int sex;
    int age;
    string address;  
};
// contacts structure 
struct Business Card
{
    struct person p[MAX];
    int size;
};

// operation menu
