Question

(vc++)定义一日期类，计算某年某月某日是今年的第几天

Answer 1

#include <iostream>
using namespace std;
class date
{
private:
int y;
int m;
int d;
public:
void setdate()
{
cout<<"请输入时间日期：xxxx xx xx"<<endl;
cin>>y>>m>>d;
}
void getdate()
{
int i,count,mon[13]={0,31,28,31,30,31,30,31,31,30,31,30,31};
count=d;
for(i=0;i<m;i++)
count+=mon[i];
if(m>2&&(y%4==0&&y%100!=0||y%400==0))
count+=1;
cout<<y<<":"<<m<<":"<<d<<"是这一年的第"<<count<<"天\n";
}
};
int main()
{
date test;
test.setdate();
test.getdate();
return 0;
}

Answer 2

#include <stdio.h>
struct date
{
int y;
int m;
int d;
}dt;
void main()
{
int i,count,mon[13]={0,31,28,31,30,31,30,31,31,30,31,30,31};
printf("请输入日期（年 月 日）:");
scanf("%d",&dt.y);
scanf("%d",&dt.m);
scanf("%d",&dt.d);
count=dt.d;
for(i=0;i<dt.m;i++)
count+=mon[i];
if(dt.m>2&&(dt.y%4==0&&dt.y%100!=0||dt.y%400==0))
count+=1;
printf("这一日是这一年的%d天\n",count++);

追问

我要VC++的，并且要用类做
