哪位大神能告诉我关于该代码switch语句中的运作情况
#include <iostream>
using namespace std;
int main()
{
double income, deduction = 0;
cout << "input income : ";
cin >> income;
int level = (income >= 1500) +
(income >= 4500) +
(income >= 9000) +
(income >= 35000) +
(income >= 55000) +
(income >= 80000);
switch(level)
{
case 6:
deduction += (income - 80000) * 0.45;
income = 80000;
case 5:
deduction += (income - 55000) * 0.35;
income = 55000;
case 4:
deduction += (income - 35000) * 0.3;
income = 35000;
case 3:
deduction += (income - 9000) * 0.25;
income = 9000;
case 2:
deduction += (income - 4500) * 0.2;
income = 4500;
case 1:
deduction += (income - 1500) * 0.1;
income = 1500;
case 0:
deduction += income * 0.03;
}
cout << "deduction = " << deduction << endl;
return 0;
}
