C++解题思路

解题思路:

注意事项:

参考代码:
#include<cstdio>
#include<iostream>
using namespace std;
int main()
{
	int price=0,gold=0;
	int p1=100000,p2=200000,p4=400000,p6=600000,p10=1000000;
	cout<<"please money=";
	cin>>price;
	if(price<=p1) //小于10万
		gold =price*0.1;
	if(price>p1 && price<=p2) //10万-20万
		gold = p1*0.1+(price-p1)*0.075;
	if(price>p2 && price<=p4  )//20万-40万
		gold = p1*0.1+(p2-p1)*0.075+(price-p2)*0.05;
	if(price>p4 && price<=p6  )//40万-60万
		gold = p1*0.1+(p2-p1)*0.075+(p4-p2)*0.05+(price-p4)*0.03;
	if(price>p6 && price<=p10  )//60万-100万
		gold = p1*0.1+(p2-p1)*0.075+(p4-p2)*0.05+(p6-p4)*0.03+(price-p6)*0.015;
	if(price>1000000 )//大于100万
		gold = p1*0.1+(p2-p1)*0.075+(p4-p2)*0.05+(p6-p4)*0.03+(p10-p6)*0.015+(price-p10)*0.01;
	cout<<gold;
	return 0;
