1009: [编程入门]数字的处理与判断

解题思路:

注意事项:

参考代码:

#include<stdio.h>

#include<math.h>

int main(void){

    int score,num,n=0,i=0,score_,t;

    scanf("%d",&score);

t=score;

while(score)

{

num = score % 10;

score /= 10;

i+=1;

score_ = score_ * 10 + num;

}

printf("%d\n",i);

    for(n=i;n>0;n--)

{

num=t/pow(10,n-1);

t=t-num*pow(10,n-1);

printf("%d ",num);

}

    printf("\n");

printf("%d\n",score_);

return 0;

}
