注意事项:

参考代码:

                    # include <stdio.h>

                    # include <stdlib.h>

                    # include <string.h>

                    int main(){

                     char s[6];

                     char s2[6];

                        gets(s);

                     int l=strlen(s);

                     int i;

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

                     for(i=0;i<l;i++){

                     printf("%c",s[i]);

                     s2[l-i-1]=s[i];

                     if(i<l-1){

                     printf(" ");

                     }

                     else{

                     printf("\n");

                     }

                     }

                     printf("%d",atoi(s2));

                        return 0;

                    }
