利用c++解利润计算问题

解题思路:数字太大书写太繁琐，在头文件处宏定义，使用if语句进行条件判断，直接输出即可

注意事项: 注意利润和奖金的关系，l代表利润

参考代码:

#include<iostream>

#define A 100000

#define B 200000

#define C 300000

#define D 400000

#define E 500000

#define F 600000

#define G 1000000

using namespace std;

int main()

{

int l,j;

cin>>l;

if(l<=A)cout<<l*0.1<<endl;

else if(l>A&&l<=B)cout<<A*0.1+(l-A)*0.075<<endl;

else if(l>B&&l<=D)cout<<A*0.1+A*0.075+(l-B)*0.05<<endl;

else if(l>D&&l<=F)cout<<A*0.1+A*0.075+B*0.05+(l-D)*0.03<<endl;

else if(l>F&&l<=G)cout<<A*0.1+A*0.075+B*0.05+B*0.03+(l-F)*0.015<<endl;

else cout<<A*0.1+A*0.075+B*0.05+B*0.03+D*0.015+(l-G)*0.01<<endl;

return 0;
