回答1：

穷举的头都晕了,还是吧数字转换成字符吧...

#include
using namespace std;

const int Mon = 1;
const int Tues = 2;
const int Wed = 3;
const int Thus = 4;
const int Fri = 5;
const int Sat = 6;
const int Sun = 7;
void change(int a)
{
switch(a)
{
case 1: cout << "一" << endl; break;
case 2: cout << "二" << endl; break;
case 3: cout << "三" << endl; break;
case 4: cout << "四" << endl; break;
case 5: cout << "五" << endl; break;
case 6: cout << "六" << endl; break;
case 7: cout << "日" << endl; break;
}

回答2：

颠三倒四撒萨大声

回答3：

给你思路自己做,第一个.
7个2进制代表和尚在一周中在那一天挑水.然后后面的条件表示出来.最后用if语句就可以了.

回答4：

#include

void main()
{
int a1,a2,a3,a4,a5,a6,a7;
for(a1=1;a1<=7;a1++)
{
if(a1==2) continue;
if(a1==4) continue;
printf("a1=%d, ",a1);
for(a2=2;a2<=7;a2++)
{
if(a2==a1) continue;
if(a2==6) continue;
printf("a2=%d, ",a2);
for(a3=1;a3<=7;a3++)
{
if(a3==a1) continue;
if(a3==a2) continue;
if(a3==3) continue;
if(a3==7) continue;
printf("a3=%d, ",a3);
for(a4=1;a4<=7;a4++)
{
if(a4==a1) continue;
if(a4==a2) continue;
if(a4==a3) continue;
if(a4==5) continue;
printf("a4=%d, ",a4);
for(a5=1;a5<=7;a5++)
{
if(a5==a1) continue;
if(a5==a2) continue;
if(a5==a3) continue;
if(a5==a4) continue;
if(a5==1) continue;
if(a5==4) continue;
if(a5==6) continue;
printf("a5=%d, ",a5);
for(a6=1;a6<=7;a6++)
{
if(a6==a1) continue;
if(a6==a2) continue;
if(a6==a3) continue;
if(a6==a4) continue;
if(a6==a5) continue;
if(a6==2) continue;
if(a6==5) continue;
printf("a6=%d, ",a6);
for(a7=1;a7<=7;a7++)
{
if(a7==a1) continue;
if(a7==a2) continue;
if(a7==a3) continue;
if(a7==a4) continue;
if(a7==a5) continue;
if(a7==a6) continue;
if(a7==3) continue;
if(a7==6) continue;
if(a7==7) continue;
printf("a7=%d, ",a7);
}
}
}
}
}
}

}

输到文件你自己弄了！~1

回答5：

改下这个是输出到out.txt文件的
#include
#include
#include
#include

using namespace std;

int main()
{
set data;
int day[7],i;
int he[7][3]={{2,4,-1},{1,6,-1},{3,7,-1},{5,-1,-1},{1,4,6},{2,5,-1},{3,6,7}};
string chr[7]={"一","二","三","四","五","六","日"};
ofstream f1("out.txt");
for (day[0]=0;day[0]<3;day[0]++)
for (day[1]=0;day[1]<3;day[1]++)
for (day[2]=0;day[2]<3;day[2]++)
for (day[3]=0;day[3]<3;day[3]++)
for (day[4]=0;day[4]<3;day[4]++)
for (day[5]=0;day[5]<3;day[5]++)
for (day[6]=0;day[6]<3;day[6]++)
{
data.clear();
for (i=0;i<7;i++)
{
if (he[i][day[i]]>0)
data.insert(he[i][day[i]]);
}
if (7==data.size())
{
f1<<"============方案==============="< for (i=0;i<7;i++)
f1<<"和尚"< }
}
f1.close();
return 0;
}

回答6：

用for循环+if判断编的，虽然有点麻烦,但是通俗易懂，其实你再可以通过逻辑简化的

#include
void main()
{
int a[7]={1,2,3,4,5,6,7},i[7],b,c,d,e,f,g,h;

for(b=0;b<=6;b++)
{
for(c=0;c<=6;c++)
{
for(d=0;d<=6;d++)
{
for(e=0;e<=6;e++)
{
for(f=0;f<=6;f++)
{
for(g=0;g<=6;g++)
{
for(h=0;h<=6;h++)
{
i[0]=a[b];
i[1]=a[c];
i[2]=a[d];
i[3]=a[e];
i[4]=a[f];
i[5]=a[g];
i[6]=a[h]; // 对1~7做全排列
if(b==c||b==d||b==e||b==f||b==g||b==h||c==d||c==e||c==f||c==g||c==h||d==e||d==f||d==g||d==h||e==f||e==g||e==h||f==g||f==h||g==h)continue; //保证没有重复的数字
if(i[0]!=2&&i[0]!=5)continue;
if(i[1]!=1&&i[1]!=6)continue;
if(i[2]!=3&&i[2]!=7)continue;
if(i[3]!=1&&i[3]!=5)continue;
if(i[4]!=4&&i[4]!=6)continue;
if(i[5]!=2&&i[5]!=5&&i[5]!=7)continue;
if(i[6]!=3&&i[6]!=7)continue; //判断是否符合要求
printf("星期一星期二星期三星期四星期五星期六星期日\n");
printf("和尚%d 和尚%d 和尚%d 和尚%d 和尚%d 和尚%d 和尚%d\n",i[0],i[1],i[2],i[3],i[4],i[5],i[6]); //若符合要求则输出

}
}
}
}
}
}
}
