写c语言不吃纸包鱼你写个？？啊

#include "stdio.h"

int main()

{

double r,a,m;

scanf("%lf",&a);

if(a<=100000) r=0.1;

else if(a>=100000&&a<200000) r=100000*0.1+(a-100000)*0.075;

else if(a>=200000&&a<400000) r=(a-200000)*0.05;

else if(a>=400000&&a<600000) r=(a-400000)*0.03;

else if(a>=600000&&a<1000000) r=(a-600000)*0.015;

else if(a>=1000000) r=(a-1000000)*0.01;

m=a-a*r;

printf("%.2f",m);

}
