这个程序用lf输出可以得到结果，但是如果用ld输出会变成一堆乱码，题目要求用ld输出，不知道问题出在哪里，感谢大佬指点。


#include <stdio.h>
#include <stdlib.h>
#include<math.h>

int main()
{   double  a;
    scanf("%lf",&a);
    if(a<100000)
        printf("bonus=%.0lf\n",0.1*a);
    if( (100000<a)&&(a<200000))
        printf("bonus=%.0lf\n",1000+(a-100000)*0.1);
    if((200000<a)&&(a<400000))
        printf("bonus=%.0lf\n",11000+(a-200000)*0.075);
    if((400000<a)&&(a<600000))
        printf("bonus=%.0lf\n",26000+(a-400000)*0.03);
    if((600000<a)&&(a<1000000))
        printf("bonus=%.0lf\n",32000+(a-600000)*0.015);
    if (a>1000000)
        printf("bonus=%.0lf\n",38000+(a-1000000)*0.01);



    return 0;
}

我知道我错哪了，谢谢
