我试了一下，无论是getc、getchar还是scanf都不能在第一个字符输入空格
只有gets可以输入空格
int main(void)
{
    int i = 0, j, k = 0, l, index;
    char c;
    //scanf("%s\n", s);
    gets(s);
    //scanf("%c", &c);
    //c = getc(stdin);
//    fflush(stdin);
//    while (c != '\n')
//    {
//        a[i++] = c;
//        c = getc(stdin);
//        //scanf("%c", &c);
//    }
//    a[i] = '\0';
//    l = strlen(a);
    gets(a);
    l = strlen(a);
    i = 0;
    while (i < l)
    {
        j = 0;
        while (a[i] != ' ' && i<l)
        {
            temp[j++] = a[i++];
            flag = 1;
        }
        temp[j] = '\0';
        if (flag == 1)
        {
            if (judge(s, temp))
            {
                k++;
                flag = 0;
                if (k == 1)
                    index = i - j;
            }
        }
        i++;
    }
    if (k == 0)
        printf("-1\n");
    else
        printf("%d %d\n", k, index);
    return 0;
}
