C++实现通讯录小功能

第C++实现通讯录小功能cout"——————————————————"endl;

cout"***********1.添加联系人***********"endl;

cout"***********2.删除联系人***********"endl;

cout"***********3.修改联系人***********"endl;

cout"***********4.查找联系人***********"endl;

cout"***********5.显示通讯录***********"endl;

cout"***********6.清空联系人***********"endl;

cout"***********0.退出通讯录***********"endl;

cout"——————————————————"endl;

}

2.退出

intmain(){

intselect=0;

cinselect;

switch(select){

case0://退出通讯录

cout"欢迎下次使用"endl;

system("pause");

return0;

break;

}

system("pause");

return0;

}

3.创建结构体

3.1创建联系人结构体

3.2创建通讯录结构体

//定义联系人结构体

//姓名、电话号码、邮箱、地址

structperson{

stringname;

stringnumber;

stringEmail;

stringaddress;

//定义通讯录结构体

structcontacts{

intpeople_num;

structpersonpersonarr[MAX];//子结构体:联系人信息

};

4.添加联系人

voidaddperson(structcontacts*p){

if(p-people_num==MAX){

cout"通讯录已满"endl;

}

else{//添加联系人信息

stringname,number,Email,address;

cout"请输入姓名："endl;

cinname;

cout"请输入电话："endl;

cinnumber;

cout"请输入邮箱："endl;

cinEmail;

cout"请输入地址："endl;

cinaddress;

p-personarr[p-people_num].name=name;

p-personarr[p-people_num].number=number;

p-personarr[p-people_num].Email=Email;

p-personarr[p-people_num].address=address;

p-people_num++;

cout"添加成功！"endl;

}

}

5.删除联系人

判断联系人是否存在

intexistperson(structcontacts*p,stringname){

for(inti=0;ip-people_num;i++){

if(p-personarr[i].name==name){

returni;

}

}

return-1;

}

若存在，获取联系人在通讯录位置，将position后面的都往前移动一个位置，覆盖之前的值

//删除联系人

voiddelperson(structcontacts*p,intposition){

while(position(p-people_num)){

p-personarr[position]=p-personarr[position+1];

position++;

}

p-people_num--;

cout"删除成功！"endl;

}

6.修改

检查要修改联系人是否存在，并获取当前位置

voidmodifyperson(structcontacts*p,intposition){

string

number,Email,address;

cout"请输入修改电话："endl;

cinnumber;

cout"请输入修改邮箱："endl;

cinEmail;

cout"请输入修改地址："endl;

cinaddress;

p-personarr[position].number=number;

p-personarr[position].Email=Email;

p-personarr[position].address=address;

cout"修改成功！"endl;

}

7.查找

voidsearchperson(structcontacts*p,intposition){

cout"姓名："p-personarr[position].name"

"

"电话："p-personarr[position].number"

"

"邮箱："p-personarr[position].Email"

"

"地址："p-personarr[position].address"

";

}

8.显示通讯录

voidshowcontact(structcontacts*p){

for(inti=0;i(p-people_num);i++){

cout"姓名："p-personarr[i].name"

"

"电话："p-personarr[i].number"

"

"邮箱："p-personarr[i].Email"

"

"地址："p-personarr[i].address"

"endl;

}

}

9.清空通讯录

voidcleancontact(structcontacts*p){

p-people_num=0;

cout"已清空！"endl;

}

#includeiostream

usingnamespacestd;

#defineMAX200

//1.菜单栏显示

voidmenu(){

cout"——————————————————"endl;

cout"***********2.删除联系人***********"endl;

cout"***********3.修改联系人***********"endl;

cout"***********5.显示通讯录***********"endl;

cout"***********6.清空联系人***********"endl;

cout"***********0.退出通讯录***********"endl;

//2.定义结构体

//2.1定义联系人结构体

//姓名、电话号码、邮箱、地址

structperson{

stringname;

stringnumber;

stringEmail;

stringaddress;

//2.2定义通讯录结构体

structcontacts{

intpeople_num;

structpersonpersonarr[MAX];//子结构体:联系人信息

//3.添加联系人

voidaddperson(structcontacts*p){

if(p-people_num==MAX){

cout"通讯录已满"endl;

}

else{//添加联系人信息

stringname,number,Email,address;

cout"请输入姓名："endl;

cinname;

cout"请输入电话："endl;

cinnumber;

cout"请输入邮箱："endl;

cinEmail;

cout"请输入地址："endl;

cinaddress;

p-personarr[p-people_num].name=name;

p-personarr[p-people_num].number=number;

p-personarr[p-people_num].Email=Email;

p-personarr[p-people_num].address=address;

p-people_num++;

cout"添加成功！"endl;

}

//4.删除联系人

//4.1检测联系人是否存在

intexistperson(structcontacts*p,stringname){

for(inti=0;ip-people_num;i++){

if(p-personarr[i].name==name){

returni;

}

}

return-1;

//删除联系人

voiddelperson(structcontacts*p,intposition){

while(position(p-people_num)){

p-personarr[position]=p-personarr[position+1];

position++;

}

p-people_num--;

cout"删除成功！"endl;

//5.修改联系人

voidmodifyperson(structcontacts*p,intposition){

string

number,Email,address;

cout"请输入修改电话："endl;

cinnumber;

cout"请输入修改邮箱："endl;

cinEmail;

cout"请输入修改地址："endl;

cinaddress;

p-personarr[position].number=number;

p-personarr[position].Email=Email;

p-personarr[position].address=address;

cout"修改成功！"endl;

//6.查找联系人

voidsearchperson(structcontacts*p,intposition){

cout"姓名："p-personarr[position].name"

"

"电话："p-personarr[position].number"

"

"邮箱："p-personarr[position].Email"

"

"地址："p-personarr[position].address"

";

//7.显示通讯录

voidshowcontact(structcontacts*p){

for(inti=0;i(p-people_num);i++){

cout"姓名："p-personarr[i].name"

"

"电话："p-personarr[i].number"

"

"邮箱："p-personarr[i].Email"

"

"地址："p-personarr[i].address"

"endl;

}

//8.清空联系人

voidcleancontact(structcontacts*p){

p-people_num=0;

cout"已清空！"endl;

intmain(){

//创建通讯录结构体变量

structcontactsc;

//初始化通讯录当前联系人个数

c.people_num=0;

intselect=0;

stringname;

while(1){

menu();

cinselect;

switch(select){

case1://添加联系人

addperson(

system("pause");

break;

case2://删除联系人

cout"请输入删除联系人的姓名：";

cinname;

if(existperson(c,name)==-1){

cout"该联系人不存在！";

}

else{

delperson(c,existperson(c,name));

}

system("pause");

break;
