编程实现从键盘上输入年份和月份,即可输出该页对应的天数含（闰年）

Posted 2023-04-14

c语言实现如下：
#include<stdio.h>
void main()

int year,month;
int day[12]=31,28,31,30,31,30,31,31,30,31,30,31;
printf("请输入年份与月份：\n");
scanf("%d%d",&year,&month);
if (year%4==0&&year%100!=0||year%400==0) day[1]++;
//判断是否为闰年，是则给原2月天数加一天。
printf("%d年%d月有%d天\n",year,month,day[month-1]);
参考技术A import java.util.Scanner;

public class Test

public static void main(String[] args)

Scanner scan = new Scanner(System.in);

System.out.print("请出入年份：");
int year = scan.nextInt();
System.out.println("请出入月份：");
int month = scan.nextInt();

int datOfMonth = 0;

switch (month)
case 1:
case 3:
case 5:
case 7:
case 8:
case 10:
case 12:
datOfMonth = 31;
break;
case 2:
if (isRunNian(year))
datOfMonth = 29;
else
datOfMonth = 28;

break;
default:
datOfMonth = 30;
break;


System.out.println(year + "年的" + month + "月共有" + datOfMonth + "天");


// 判断是否是闰年
public static boolean isRunNian (int year)
boolean flag = false;

if (year/4 == 0
|| (year/100 == 0 && year/400 != 0))
flag = true;


return flag;

python输入年份月份输出天数_输入年份月份输出对应的天数

方法1.

//数据输入

Scanner scanner=new Scanner(System.in);

System.out.println("请输入年份(例如2012)");

int year=scanner.nextInt();

System.out.println("请输入月份");

int mounth=scanner.nextInt();

scanner.close();

//判断是不是闰年

boolean isrui=(year%4==0&&year%100!=0) || year%400==0;

//判断月份

if(isrui)

switch(mounth)

case 1:

System.out.println(year+"年"+mounth+"月有"+31+"天");

break;

case 2:

System.out.println(year+"年"+mounth+"月有"+29+"天");

break;

case 3:

System.out.println(year+"年"+mounth+"月有"+31+"天");

break;

case 4:

System.out.println(year+"年"+mounth+"月有"+30+"天");

break;

case 5:

System.out.println(year+"年"+mounth+"月有"+31+"天");

break;

case 6:

System.out.println(year+"年"+mounth+"月有"+30+"天");

break;

case 7:

System.out.println(year+"年"+mounth+"月有"+31+"天");

break;

case 8:

System.out.println(year+"年"+mounth+"月有"+31+"天");

break;

case 9:

System.out.println(year+"年"+mounth+"月有"+30+"天");

break;

case 10:

System.out.println(year+"年"+mounth+"月有"+31+"天");

break;

case 11:

System.out.println(year+"年"+mounth+"月有"+30+"天");

break;

case 12:

System.out.println(year+"年"+mounth+"月有"+31+"天");

break;

else

switch(mounth)

case 1:

System.out.println(year+"年"+mounth+"月有"+31+"天");

break;

case 2:

System.out.println(year+"年"+mounth+"月有"+28+"天");

break;

case 3:

System.out.println(year+"年"+mounth+"月有"+31+"天");

break;

case 4:

System.out.println(year+"年"+mounth+"月有"+30+"天");

break;

case 5:

System.out.println(year+"年"+mounth+"月有"+31+"天");

break;

case 6:

System.out.println(year+"年"+mounth+"月有"+30+"天");

break;

case 7:

System.out.println(year+"年"+mounth+"月有"+31+"天");

break;

case 8:

System.out.println(year+"年"+mounth+"月有"+31+"天");

break;

case 9:

System.out.println(year+"年"+mounth+"月有"+30+"天");

break;

case 10:

System.out.println(year+"年"+mounth+"月有"+31+"天");

break;

case 11:

System.out.println(year+"年"+mounth+"月有"+30+"天");

break;

case 12:

System.out.println(year+"年"+mounth+"月有"+31+"天");

break;

方法二.

Scanner s=new Scanner(System.in);

System.out.println("请输入年份----");

int a=s.nextInt();

System.out.println("请输入月份----");

int b=s.nextInt();

int day=0;

//可以输入，但是未完！！！

switch(b)

case 1:

case 3:

case 5:

case 7:

case 8:

case 10:

case 12:

day=31;

break;

case 4:

case 6:

case 9:

case 11:

day=30;

break;

case 2:

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

day=29;

else

day=28;

break;

System.out.println(a + "年" + b + "月份 " + "有" + day + "天");
