解题思路:
注意事项:
参考代码:
#include<stdio.h>
int main()
{
int num,indiv,ten,hundred,thousand,ten_thousand,place;
scanf("%d",&num);
if(num>9999)
place=5;
else if(num>999)
place=4;
else if(num>99)
place=3;
else if(num>9)
place=2;
else place=1;
printf("%d\n",place);
ten_thousand=num/10000;
thousand=(int)(num-ten_thousand*10000)/1000;
hundred=(int)(num-ten_thousand*10000-thousand*1000)/100;
ten=(int)(num-ten_thousand*10000-thousand*1000-hundred*100)/10;
indiv=(int)(num-ten_thousand*10000-thousand*1000-hundred*100-ten*10);
switch(place){
case 5:printf ("%d %d %d %d %d\n",ten_thousand,thousand,hundred,ten,indiv);
printf("%d%d%d%d%d\n",indiv,ten,hundred,thousand,ten_thousand) ;
break;
case 4:printf ("%d %d %d %d\n",thousand,hundred,ten,indiv);
printf("%d%d%d%d%d\n",indiv,ten,hundred,thousand) ;
break;
case 3:printf ("%d %d %d\n",hundred,ten,indiv);
printf("%d%d%d\n",indiv,ten,hundred) ;
break;
case 2:printf ("%d %d\n",ten,indiv);
printf("%d%d\n",indiv,ten) ;
break;
case 1:printf("%d\n",indiv);
printf("%d\n",indiv) ;
break;
}
return 0;
}
