动态实现通讯录

动态实现，借用之前以及写好的通讯录代码，在结构体内添加柔性数组

主要是柔性数组的使用

	int i = 0;
	List *p = (List*)malloc(sizeof(List)+100 * sizeof(int));
	p->i = 100;
	for (i = 0; i < 100; i++){
		p->a[i] = i;
		addinfor(p);
	}

#include<stdio.h>
#include<Windows.h>
#include<string.h>
#include<stdlib.h>
#pragma warning(disable:4996)

typedef struct address{
	char Name[10];
	int Sex;
	int Age;
	char Num[12];
	char Address[32];
	int i;
	int a[];

}List;

void addinfor(List *l){  //添加联系人
	//int s , age, num, add;
	printf("请输入用户姓名:");
	scanf("%s", l->Name);
	printf("\n请输入用户性别（1.男 ， 2.女）：");
	scanf("%d", &(l->Sex));
	printf("\n请输入用户年龄:");
	scanf("%d", &(l->Age));
	printf("\n请输入用户的电话号码：");
	scanf("%s", l->Num);
	printf("\n请输入用户的地址:");
	scanf("%s", l->Address);

}

void showlist(List l){  //show函数
	if (strcmp(l.Name, "NULL") == 0) {
		return;
	}
	printf("\n姓名：%s", l.Name);
	if (l.Sex == 1){
		printf("\n性别: 男");
	}
	else{
		printf("\n性别: 女");
	}

	printf("\n电话号码：%s", l.Num);

	if (strcmp(l.Name, s) == 0){
		return 1;
	}
	else{
		return 0;

}

void changeList(List *l){  //修改联系人
	printf("输入你要修改的联系人:");
	char s[10];

			strcpy(l[i].Name, "NULL");
			printf("删除成功\n");
			return;
		}
	}
	printf("查无此人\n");
}

	int i = 0;
	List *p = (List*)malloc(sizeof(List)+100 * sizeof(int));

后续更新修改后代码
