个人所得税计算程序

思路是，先在类中写好自定义比较函数，再用针对容器的算法对容器内的内容实现自定义排序

注意类的成员是private，需要调用成员函数来访问，另外结果保留一位小数

#include <iostream>
#include <vector>
#include <algorithm>
// write your code here......

using namespace std;

class Employee {

    private:
        string name;
        double salary;
    // write your code here......
    public:
    void set_name(string name){
        this->name = name;
    }
    void set_salary(double salary){
        this->salary = salary;
    }
    double get_salary(){
        return this->salary;
    }
    string get_name(){
        return this->name;
    }
    Employee(string a, double b) :name(a), salary(b) {}
};
 bool mycompare_salary(Employee &emp1,Employee &emp2){
    if(emp1.get_salary()>emp2.get_salary()){
        return true;
    }
    else return false;
}
int main() {

    // write your code here......
    Employee zhangsan("张三",6500.00);

    Employee wangwu("王五",100000.00);
    vector<Employee> emp;
    cout.setf(ios::fixed);
    cout.precision(1);
    emp.push_back(zhangsan);
    emp.push_back(lisi);
    emp.push_back(wangwu);

        }
        else if((iter->get_salary()-3500.00)>1500&&(iter->get_salary()-3500.00)<=4500){
