编写一个学生姓名结构类程序

#include<iostream.h>

classStudent

(

private:

charname[8];

intcode;

intsex;

intage;

public:

Student(charn[],intc,intszinta)

for(inli=0;i<8;i++)

name[i]=n[i];

code=c;

sex=s;

age=a;

)

voiddisplayO

cout<<MName:";

for(inti=0;i<8;i++)

cout<<name[i];

cout<<"Code:1*<<code<<"sex:"<<((sex==l)?"Male":"Female")<<

age:"<<age<<endl;

)

);

voidmain()

(

charnl[8]="Tom";

Student$1(01,100,1,18);

sl.displayO;

)

增加静态量

#include<iostream.h>

classStudent

voiddisplayO

(

cout<<"Name:w;

for(inti=0;i<8;i++)

cout<<name[i];

cout<<"Code:"<<code<<"sex:"<<((sex==l)?"Male":"Femalen)<<

age:"<<age<<endl;

)

staticintgetNumQ

(

returnnumber;

)

staticvoiddisp2(Students)

cout<<^'Name:,,;

for(inti=0;i<8;i++)

cout<<[i];

cout<<"Code:1*<<s.code<<"sex:"<<((s.sex==1)?"Male":"Female")<<

intStudent::number=O;

voidmain()

char*getName(){returnname;}

voiddisplayO

(

cout<<"姓名:"；

for(inti=0;i<8;i++)

cout<<name[i];

cout<<"编号:"<<code<<n性别："<({sex==l)?"男女。<<”年

§$:"<<age<<endl;

)

);

classCEmployee:publicCPerson

)

voiddisplayO

CPerson::display();

cout<<"部门:"；

for(inti=0;i<10;i++)

cout<<department[i];

cout<<"工资”<〈salary<<endl;

)

)；

voidmain()

(

charnamel[8]="张三"；

chardl[10]="贝才务部”;

CEniployee巳1(［间1漳1,88888,1,30,d1,2000);

el.displayO;

)

编写年月日

#include<iostream.h>

classDate

(

intyear;

intmonth;

intday;

public:

Date(inty,intm,intd)

yedr=y;rnonlli=rT);dciy=d;

)

voidsetYear(inty){year=y;}

voidsetMonth(intm){month=m;}

voidsetDay(intd){day=d;}

intgetYear(){returnyear;}

intgetMonth(){returnmonth;}

intgetDay(){returnday;}

voiddisp()

(

cout<<year<<"/"<<month<<7"<<day<<endl;

)

voidaddldayO

if(day==31)

if(month==12){

year++；

month=l;

day=l;

)

else

(

month++;

day=l;

)

return;

)

if(day<30&&month!=2){

day++；

return;

)

if(month==2)

(

if(day==28)

if(year%400==O||year%4==0&&year%100!=0)

day++;

else

rnonlh++;
