scanf("%s", pinfo->_address);
}添加联系人
void AddressBookAdd(AddressBook* pbook, AddressInfo* pinfo)
{
assert(pbook&&pinfo);
if (pbook->_size == pbook->_capacity)
{
pbook->Information = realloc(pbook->Information, sizeof(AddressInfo)*(pbook->_capacity) * 2);

strcpy(pbook->Information[pbook->_size]._phone, pinfo->_phone);
strcpy(pbook->Information[pbook->_size]._address, pinfo->_address);
pbook->_size++;
}
删除联系人
void AddressBookDel(AddressBook* pbook, const char* name)
{
size_t i = 0;
for (i = 0; i < pbook->_size; i++)
{
if (strcmp(pbook->Information[i]._name, name) == 0)
{
break;
}
}
if (i == pbook->_size)
{
printf("未找到联系人%s\n\n", name);
return;
}
for (i = i + 1; i < pbook->_size; i++)
{
AddressInfoCopy(&pbook->Information[i - 1], &pbook->Information[i]);
//联系人的挪移
}
pbook->_size--;
}查找联系人：
AddressInfo* AddressBookFind(AddressBook* pbook, const char* name)
{
AddressInfo* pinfo;
pinfo = (AddressInfo*)malloc(sizeof(AddressInfo));
size_t i = 0;
for (i = 0; i < pbook->_size; i++)
{
if (strcmp(pbook->Information[i]._name, name) == 0)
{
return &pbook->Information[i];
}
}
printf("没有找到联系人%s\n\n", name);
return NULL;
}
修改联系人
void AddressBookChange(AddressBook* pbook, const char* name)
{
AddressInfo* pinfo;
pinfo = (AddressInfo*)malloc(sizeof(AddressInfo));
pinfo = AddressBookFind(pbook, name);
if (pinfo == NULL)
{
return;
}
printf("请输入联系人新的信息\n");
Input(&pinfo);
}联系人的挪移：
void AddressInfoCopy(AddressInfo* tar, AddressInfo* src)
{
strcpy(tar->_name, src->_name);
strcpy(tar->_phone, src->_phone);
strcpy(tar->_address, src->_address);
tar->_age = src->_age;
tar->_sex = src->_sex;
}打印所有联系人信息
void AddressBookShow(AddressBook* pbook)
{
size_t i = 0;
printf("姓名\t电话号码\t年龄\t性别\t住址\n");
for (i = 0; i < pbook->_size; i++)
{
According(&pbook->Information[i]);
}
}单独打印联系人信息
void According(AddressInfo* pinfo)
{
printf("%s\t", pinfo->_name);
printf("%s\t\t", pinfo->_phone);
printf("%d\t", pinfo->_age);
switch (pinfo->_sex)
{
case man:
printf("man\t");
break;
case woman:
printf("woman\t");
break;
default:
printf("无法识别\t");
break;
}
printf("%s\n", pinfo->_address);
}
联系人信息以二进制形式写入文件
void AddressBookSave(AddressBook* pbook, const char* filename)
{
assert(pbook&&filename);
FILE* fp = fopen(filename, "w");
for (size_t i = 0; i < pbook->_size; i++)
{
fwrite(&pbook->Information[i], sizeof(AddressInfo), 1, fp);
}
AddressInfo end;
end._age = -1;
fwrite(&end, sizeof(AddressInfo), 1, fp);
fclose(fp);
}从文件读取联系人信息
void AddressBookLoad(AddressBook* pbook, const char* filename)
{
assert(pbook&&filename);
FILE* fp = fopen(filename, "r");
AddressInfo info;
while (1)
{
fread(&info, sizeof(AddressInfo), 1, fp);
if (info._age == -1)
{
break;
}
AddressBookAdd(pbook, &info);
}
fclose(fp);
}根据联系人姓名进行排序（用冒泡排序简单实现）
void AddressBookSort(AddressBook* pbook)
{
size_t i = 0;
size_t j = 0;
for (i = 0; i < pbook->_size; i++)
{
for (j = 0; j < pbook->_size-i - 1; j++)
{
if (strcmp(pbook->Information[j]._name, pbook->Information[j + 1]._name)>0)
{
AddressBookSwap(&pbook->Information[j], &pbook->Information[j + 1]);
}
}
}
}
两个联系人信息的交换
void AddressBookSwap(AddressInfo* pInfo1, AddressInfo* pInfo2)
{
AddressInfo* tmp;
tmp = (AddressInfo*)malloc(sizeof(AddressInfo));
AddressInfoCopy(tmp, pInfo1);
AddressInfoCopy(pInfo1, pInfo2);
AddressInfoCopy(pInfo2, tmp);
free(tmp);
