tips:1.计算两日期距元年元旦的天数相减再+1
2.计算天数用bool值和2维数组感觉很直观
3.输入格式用c的scanf很清晰

思路:
将小的日期记为A，大的日期记为B
计算 A年的 1.1 (A11) 到B年1.1 (B11)的天数 A11toB11 (记得计算闰年)
计算 A到本年的日期 Ato11
计算 B到本年的日期 Bto11
日期差值为
A11toB11 + Bto11 - Ato11
代码如下：
#include
#include
#include
using namespace std;
int beginDayOfMonth[13][2] = {
0, 0,
0, 0,
31, 31,
59, 60,
90, 91,
120, 121,
151, 152,
181, 182,
212, 213,
243, 244,
273, 274,
304, 305,
334, 335
};
int isRunYear(int year)
{
return year%100 != 0 && year%4 == 0 || year%400 == 0 ? 1:0;
}
int dayto11(int year, int month, int day)
{
int isRun = isRunYear(year);
if(isRun)
{
return day + beginDayOfMonth[month][1];
}
else return day + beginDayOfMonth[month][0];
// return day + beginDayOfMonth[month][isRun]; 但这里需要保证 isRun 只取 01
}
int main()
{
int AtoA11, BtoB11, A11toB11;
int y1, m1, d1;
int y2, m2, d2;
int disDay;
while(scanf("%4d%2d%2d", &y1, &m1, &d1) != EOF)
{
scanf("%4d%2d%2d", &y2, &m2, &d2);
if(y1 > y2 || (y1 == y2 && m1 > m2) || (y1 == y2 && m1 == m2 && d1 > d2))
{
int tmp = y1;
y1 = y2;
y2 = tmp;
tmp = m1;
m1 = m2;
m2 = tmp;
tmp = d1;
d1 = d2;
d2 = tmp;
}
AtoA11 = dayto11(y1, m1, d1);
BtoB11 = dayto11(y2, m2, d2);
// cout << AtoA11 << endl;
// cout << BtoB11 << endl;
A11toB11 = 0;
for(int i = y1; i < y2; i++)
{
if(isRunYear(i)) A11toB11 += 366;
else A11toB11 += 365;
}
disDay = A11toB11 + BtoB11 - AtoA11 + 1; // 这里是 把 最后一天的也给算上
printf("%d\n", disDay);
}
return 0;
}思路二
主要参考“看不见的风景201803281904”。
这里我对计算距离0年1月1日的方法进行了修改，
#include<cstdio>
#include<iostream>
#include<cmath>
using namespace std;
int mon[12] = {0, 31, 59, 90, 120, 151, 181, 212, 243, 273, 304, 334};
int sumRun1(int y)
{
// 计算[0, y]之间 闰年 的次数
// 若 y在 0000 年之前, 则为负数，记录了[y, -1]闰年的次数(的相反数)
return 1 + floor(double(y-1)/4+1e-4) - floor(double(y-1)/100+1e-4) + floor(double(y-1)/400+1e-4);
// y-1是因为如果 第y年是闰年，那么会对 00000101至 y+1年1月1日 的天数造成影响
// +1 是为了 将0000年记为闰年
// floor(double(y-1)/4+1e-4) 是为了 计算在公元前的闰年
// + 1e-4 是为了避免浮点误差
/*
其实这段代码的效果就是为了对应
年数
-5 -4 -3 -2 -1 0 1 2 3 4 5 6
累计闰年个数
-1 -1 0 0 0 0 1 1 1 1 2 2
*/
}
int isRunYear(int year)
{
return year%100 != 0 && year%4 == 0 || year%400 == 0 ? 1:0;
}
int sumRun2(int y) // 和这个效果是一样的
{
int numOfRun = 0;
if(y < 0)
{
for(int i = y; i < 0; i++)
{
if(isRunYear(i)) numOfRun--;
}
}
else
{
for(int i = 0; i < y; i++)
{
if(isRunYear(i)) numOfRun++;
}
}
return numOfRun;
}
// 给出年月日，计算距离0000年 1 月 1 日的 天数
int calto01(int y, int m, int d)
{
return sumRun1(y) + y * 365 + mon[m-1] + d-1 + (((y%100 != 0 && y%4 == 0) || y%400 == 0) && m > 2);
}
int main()
{
int disto01[2], year, month, day;
int y0, m0, d0;
int y1, m1, d1;
while(scanf("%4d%2d%2d", &y0, &m0, &d0) != EOF)
{
scanf("%4d%2d%2d", &y1, &m1, &d1);
disto01[0] = calto01(y0, m0, d0);
disto01[1] = calto01(y1, m1, d1);
// cout << disto01[0] << " " << disto01[1] << endl;
printf("%d\n", abs(disto01[0] - disto01[1]) + 1);
}
return 0;
}

//再加上终止日期距离1月0日的偏移即得到实际相差天数。
