装个逼，用动态内存分配。

<span style="font-size:18px;">#include <stdio.h>#include <malloc.h>int main(){    float* num;    float n,sum;    int i = 0,j,temp;    scanf("%f",&n);    while(n != 0.00) /*输入测试样例*/    {    if(i == 0)            num = (float*)malloc(sizeof(float));        else            num = (float*)realloc(num,(i+1)*sizeof(float));        num[i++] = n;        scanf("%f",&n);    }    temp = i;    for(i = 0; i < temp; i++ ) /*遍历测试样例*/    {    sum = 0.0;    j = 2;    while(1)    {        sum += 1.0/j;        if(sum >= num[i])/*数列的和大于等于测试样例*/                break;         j++;     }    printf("%d card(s)\n",j-1);    }       free(num);          return 0;}</span>
