思路：要一边转化字符串，一边取整，或者求余！！！！

#include<stdio.h>  #include<string.h> #define N 800 int main(){char s1[N];char ch;long i, temp, sum, l, num, j, s2[N];while (scanf("%s %c %ld", s1, &ch, &num) != EOF){memset(s2, 0, sizeof(s2));l = strlen(s1);sum = 0;if (ch == '/'){temp = 0;for(i = 0; i < l; i++){temp = temp * 10 + s1[i] - '0';if (temp >= num){++sum;s2[sum] = temp / num;temp %= num;}else++sum;}j = 1;while ((s2[j] == 0) && (j < sum))j++;for(i = j; i <= sum; i++)printf("%ld", s2[i]);printf("\n");}else{for(i = 0; i < l; i++){sum = sum * 10 + s1[i] - '0';sum %= num; }printf("%ld\n", sum);}}return 0;}
