NextDate函数黑盒测试

NextDate函数黑盒测试
1测试程序源代码
#include <iostream>
using namespace std;
void NextDate(int year,int month,int day);
void main()
{
int year=0,month=0,day=0;
NextDate(year,month,day);
}
void NextDate(int year,int month,int day)
{
cout<<"请输入年份："<<endl;
cin>>year;
while(!(year>=1811 && year<=2013))
{
cout<<"年份超过界限，请重新输入"<<endl;
cin>>year;
}
cout<<"请输入月份："<<endl;
cin>>month;
while (month>12||month<1)
{
cout<<"月份输入有误，请重新输入"<<endl;
cin>>month;
}
cout<<"请输入日期："<<endl;
cin>>day;
while (day>31||day<1)
{
cout<<"日期输入有误，请重新输入"<<endl;
cin>>day;
}
if((year%4==0 && year%100!=0) || (year%400==0)) //检查闰年；
{
int i=0;
i=day-29;
while(month==2&&i>0)
{
cout<<"本月是闰月，请在1-29之间从新输入日期"<<endl;
cin>>day;
}
if(month==2&&day==29)
{
month=3;
day=1;
}
else day++;
}
else day++;
//月底计算；
switch(month)
{
case 1:
case 3:
case 5:
case 7:
case 8:
case 10:
if (day==32)
{
