解答:

#include <iostream>
using namespace std;

int main()
{
	float salary = 0;
	float tax = 0;
	while (salary>=0)
	{
		cout << "请输入您的工资:";
		cin >> salary;
		if (cin.fail())break;
		if (salary <= 5000)
		{
			tax = 0;
		}
		else if (salary <= 15000)
		{
			tax = (salary-5000) * 0.1;
		}
		else if (salary <= 35000)
		{
			tax = (salary - 15000) * 0.15 + 10000 * 0.1;
		}
		else if (salary > 35000)
		{
			tax = (salary - 35000) * 0.2 + 20000 * 0.15 + 10000 * 0.1;
		}
		cout << salary << "元的税收为:" << tax << endl;
	}
	cout << "Bye!" << endl;


	return 0;
}
