C语言实现通讯录—动态顺序表

之前我有一篇博客写的是静态顺序表实现通讯录，但是静态顺序表有一个很大的缺陷就是，如果存满了，就不能在继续存储了。

为了改进之前的版本，本次将实现动态顺序表的通讯录，可以动态开辟空间，不用担心空间存储满的问题。环境和之前的一样，是：VS2008；

此次为了规范，建立的是.c文件

	People* _a;

	size_t _capacity;	// 容量

void AddPeople(PeopleBook* PB);//添加联系人
void DeletePeople(PeopleBook* PB);//删除联系人
void FindPeople(PeopleBook* PB);//查找联系人并返回联系人信息
void ChangePeople(PeopleBook* PB);//修改联系人信息
void PrintPeopleBook(PeopleBook* PB);//打印所有联系人信息
void DestroyPeople(PeopleBook* PB);//销毁所有联系人信息
void Swap(People* a,People* b);//交换两个联系人信息，
