一、日期类

#include<iostream>using namespace std;class date{    int year;    int month;    int day;public:    date(int a=1, int b=1, int c=1)    {        if(b<0||b>12||c<0||c>31)        {            cout<<"您输入的参数有误，请重新输入月日:"<<endl;            cin>>b>>c;        }        year=a;        month=b;        day=c;    }    ~date()    {    }    void display();};void date::display(){    cout<<year<<"-"<<month<<"-"<<day<<endl;}void main(){    date a;    a.display();    date b(2017,13,28);    b.display();}

二、集合类

#include<iostream>using namespace std;class atest{    int a[10];public:    atest(int *b)    {        for(int i=0;i<10;i++)        *(a+i)=*(b+i);    }    void display();    int checkele(int b);};void atest::display(){    for(int i=0;i<10;i++)        cout<<*(a+i)<<(i%5==4?'\n':'\t');}int atest::checkele(int b){    for(int i=0;i<10;i++)        if(*(a+i)==b)            return i+1;    return -1;}void main(){    int b[10]={1,2,3,4,5,6,7,8,9,10};    atest a(b);    a.display();    int n;    cout<<"请输入要查找的元素：\n";    cin>>n;    cout<<"您要查找的元素位于："<<a.checkele(n)<<endl;}

三、职工类

#include<iostream>using namespace std;#include<string.h>class staff{    int idnum;    char *name;    int gender;    float basicin;    float bouns;public:    staff(int a=0,char *b=0,int c=3, float d=0, float e=0)    {        idnum=a;        if(b==0)            name=0;        else        {            name=new char[strlen(b)+1];            strcpy(name,b);        }        gender=c;        basicin=d;        bouns=e;    }    ~staff()    {        delete []name;    }    void changetotal(float a,float b);    void display()    {        cout<<"ID number"<<'\t'<<"Name"<<'\t'<<"Gender"<<'\t'<<"Basic income"<<'\t'<<"Bouns"<<'\t'<<"Total"<<endl;        cout<<idnum<<'\t'<<name<<'\t';        if(gender==1)            cout<<"man";        else if(gender==2)            cout<<"woman";        else            cout<<"unknow";        cout<<'\t'<<basicin<<'\t'<<bouns<<'\t'<<basicin+bouns<<endl;    }};void staff::changetotal(float a,float b){    basicin=a;    bouns=b;}void main(){    char a[20]="张三";    staff b(100,a,1,1782.3,2000);    b.display();    b.changetotal(1000,1000);    b.display();}
