[编程入门]利润计算-题解（C语言代码）

解题思路:宏定义

注意事项:

参考代码:

#include"stdio.h"

#define A 100000

#define B 200000

#define C 400000

#define D 600000

#define E 1000000

#define J1 0.1

#define J2 0.075

#define J3 0.05

#define J4 0.03

#define J5 0.015

#define J6 0.01

#define SW (A*J1)                     //<=10w

#define REW (SW+(B-A)*J2)      //<=20w

#define SIW (REW+(C-B)*J3)     //<=40w

#define LW (SIW+(D-C)*J4)       //<=60w

#define YW (LW+(E-D)*J5)        //<=100w

int main()

{

int x,y;

scanf("%d",&x);

if(x<=A)

y=x*J1;

else if(x<=B)

y=SW+((x-A)*J2);

else if(x<=C)

y=REW+((x-B)*J3);

else if(x<=D)

y=SIW+((x-C)*J4);

else if(x<=E)

y=LW+((x-D)*J5);

else if(x>E)

y=YW+((x-E)*J6);

printf("%d",y);

    return 0;

}
