2.输入年份,判断该年是否为闰年.用逻辑(!)做

inputaif(amod4)=0and(amod100)>0thenprint"是闰年"elseif（amod400）=0thenprint"是润年"elseprint"不是闰年"endifendi

inputaif((amod4)=0and(amod100)>0)or(amod400)=0thenprint"是闰年"elseprint"不是闰年"再问：mod是什么再答：mod是求余数，即4mod

可能是太简单了,难得有人回读了,网上一大堆.我手写,没调试：dimy%onerrorgotoline1y=inputbox("输入年份：")'input-inputboxif((ymod4)=0and

inputaif((amod4)=0and(amod100)>0)or(amod400)=0thenprint"是闰年"elseprint"不是闰年"你反着用应该行吧.

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

inputn;if(nmod4=0)and(nmod100)0thenprint('yes')elseifnmod400=0thenprint('yes')elsewriteln('no');endi

#includemain(){intt;intis(intt);printf("输入年份为");scanf("%d\n",&t);t=is(t);if(t=1)printf("%d是闰年",t);el

//c++#includeusingnamespacestd;intmain(){intyear;cin>>year;if((year%400==0)||((year%4==0)&&(year%

intjudge_leap_year(){intyear;intok=0;printf("Pleaseinputtheyear:");scanf("%d",&year);if(yea

inputaif((amod4)=0and(amod100)>0)or(amod400)=0thenprint"是闰年"elseprint"不是闰年"你反着用应该行吧.这样可以么?

#includemain(){intt;intis(intt);printf("输入年份为");scanf("%d\n",&t);t=is(t);if(t=1)printf("%d是闰年",t);el

intyearprintf("请输入一个年份");scanf("%d",&year);if((year%4==0&&year%100!=0)||year%400==0)print("闰年\n");el

闰年的条件:年份被4整除,但不能被100整除?或者被400整除?如果是的话,在任一单元格输入公式:=or(and(mod(year(now()),4)=0,mod(year(now()),100)>0

#includemain(){intn;printf("输入年份:");scanf("%d",&n);if(n%4==0&&n%100!=0||n%400==0)printf("闰年\n");else

#includevoidmain(){\x09intyear;\x09printf("请输入年份：");\x09scanf("%d",&year);\x09if((year%4==0&&year/10

if((AYearmod4)=0)and(((AYearmod100)0)or((AYearmod400)=0))thenShowMessage('闰年')elseShowMessage('非闰年')

#include"stdio.h"#include"conio.h"intfun(intn){intflag=0;if(n%4==0){if(n%100!=0)flag=1;}if(n%400==0)

#includevoidJudge(inty){while(1){printf("请输入要计算的年份：\n");scanf("%d",&y);if((y%100==0)&&(y%400==0)||(y

看看：http://hi.baidu.com/%D7%F6%B6%F8%C2%DB%B5%C0/blog/item/e0908bf1971e64de7831aa4c.html再问：小的看不懂

将scanf("%d%d",y,m);改为scanf("%d%d",&y,&m);main函数最后加上return（0）；m与y须初始化.做完以上OK
