c++的通讯录管理系统

纯纯c++入门，学过C语言的就知道了，用数组写的

#include 
#include 
#define MAX 100//后期方便修改通讯录大小
using namespace std;
struct Person//定义结构体数组，应该是这个名字
{
	int num;
	string name;
	string m_sex;
	int m_age;
	string phone;
	string address;
};
struct addressbooks//结构体数组
{
	struct Person personarray[MAX];
	int m_size;
};
void showmenu()//通讯录可以进行的操作
{
	cout<<"****************************"<m_size==1000)
	{
		cout<<"通讯录已满！！!"<>name;
		per->personarray[per->m_size].name=name;

		cout<<"请输入性别"<>sex;
			if(sex==1||sex==2)
			{
				if(sex==1)
					per->personarray[per->m_size].m_sex=str1;
				else if(sex==2)
					per->personarray[per->m_size].m_sex=str2;
				break;
			}

		per->personarray[per->m_size].phone=phone;

		cout<<"请输入地址"<>address;
		per->personarray[per->m_size].address=address;

		per->m_size++;
	}
		
}
void showperson(struct addressbooks *per)//遍历函数，把数组的拉出来遛一下

	if (per->m_size==0)

	return false;//这个别上在for循环里了，刚开始写进去，找了好久才发现
}
int exist(struct addressbooks *per,int num)//该函数主要是为了返回一个i，方便对指定的数据进行处理

 应该是没什么大问题
