闰年是指能被4整除但不能被100整除的年份,或者能被400整除的年份,编写一个程序,判断输入的年份是否为闰年

C++ 如下:

//---------------------------------------------------------------------------

#include <vcl.h>
#pragma hdrstop
#include <iostream.h>

//---------------------------------------------------------------------------

#pragma argsused
int main(int argc, char* argv[])
{
int year;
cout<<"请输入一个年份(判断是否为闰年): ";
cin>>year;
if (((year%4==0) && (year%400==0)) || ((year%4==0) && (year%100!=0)))
cout<<year<<"年是闰年! "<<endl;
else cout<<year<<"年不是闰年! "<<endl;
cin.get();
cin.get();

return 0;
}
//---------------------------------------------------------------------------

#include<stdio.h>
void main()
{
int years;
printf("\n请输入年份:\n");
scanf("%d",&years);
if((years%4==0)&&(years%100!=0)||(years%400
