Question

C语言输入年份和天数输出对应的年月日

Answer 1

C语言输入年份和天数输出对应的年月日的源代码如下：

#include <iostream>

int day(int &year, int &month);

int main()

{

 int year{};

int month{};

std::cout << "请输入年和月(空格隔开):";

std::cin >> year >> month; 

std::cout << "该月天数:" << day(year, month) << '\n'; 

return 0;

}

扩展资料

1、C++ 标准库没有提供所谓的日期类型。C++ 继承了 C 语言用于日期和时间操作的结构和函数。为了使用日期和时间相关的函数和结构，需要在 C++ 程序中引用 <ctime> 头文件。

2、有四个与时间相关的类型：clock_t、time_t、size_t 和 tm。类型 clock_t、size_t 和 time_t 能够把系统时间和日期表示为某种整数。

Answer 2

#include "stdio.h"
bool ifLeapYear(int year)//判断是不是云年
{
if((year%400==0)||((year%4==0)&&(year%100!=0)))
return true;
else
return false;
}
void main()
{
int year,date,i;
int month1[12]={31,29,31,30,31,30,31,31,30,31,30,31};
int month2[12]={31,28,31,30,31,30,31,31,30,31,30,31};
bool flag;
printf("请输入年份和天数\n");
scanf("%d%d",&year,&date);
if(date>366)
{
printf("输入错误！\n");
return;
}
flag=ifLeapYear(year);
if(flag)
for(i=0;i<12;i++)
{
if(date<=month1[i]) break;
date=date-month1[i];
}
else
for(i=0;i<12;i++)
{
if(date<=month2[i]) break;
date=date-month2[i];
}
printf("是%d月%d号",i+1,date);
}
