}
题目三输入两次年
月日(不分时间先后),年月日格式为xxxx-xx-xx,并用enter间隔开两次时间。最后输出两次时间的天数之差(需要考虑到闰年与平年)

2016-3-1
标准输出:
1502

题目四数字黑洞6174:给定任一个各位数字不完全相同的4位正整数,若先把4个数字按递减排序,再按递增排序,然后用第一个数字减第二个数字,将得到一个新的数字。一直重复这样做,会停在有“数字黑洞”之称的6174,这个神奇的数字也叫Kaprekar常数。
给定任意4位正整数,请编写程序演示到达数字黑洞6174的过程。
输入描述:输入给出一个(0,10000)区间内的正整数
输出描述:若
N
N
N的4位数字全相等,则在一行内输出N-N=0000
;否则将计算的每一步在一行内输出,直到6174作为差出现为止。每行中间没有空格,每个数字按4位格式输出,见如下样例。
标准输入:
6767
标准输出:
7766-6677=1089
9810-0189=9621
9621-1269=8352
8532-2358=6174
#include#include#include
using namespace std;
int main() {int n;
cin >>n;
if (n % 1111 == 0)
printf("%d-%d=0000", n, n);
else {int dif;
do { vectorv1(4);
v1[0] = n % 10;
v1[1] = (n % 100) / 10;
v1[2] = (n % 1000) / 100;
v1[3] = n / 1000;
sort(v1.begin(), v1.end());
int num1 = v1[3] * 1000 + v1[2] * 100 + v1[1] * 10 + v1[0];
int num2 = v1[0] * 1000 + v1[1] * 100 + v1[2] * 10 + v1[3];
dif = num1 - num2;
n = dif;
printf("%04d-%04d=%04d\n", num1, num2, dif);
} while (dif != 6174);
}
}
题目五判断是否为水仙花数。水仙花数指一个三位数,它的每个位上的数字的三次幂之和等于它本身。示例:
1
3
+
5
3
+
3
3
=
153
1^3+5^3+3^3=153
13+53+33=153
标准输入
135
标准输出
不是
#includeusing namespace std;
int main() {int n;
cin >>n;
if (n == 153 || n == 370 || n == 371 || n == 407) cout<< "是";
else cout<< "不是";
}
