第八周 个人所得税计算器

个人所得税相关代码

方法1:

#include <iostream>

using namespace std;

int main()
{
    double dsalary,dtex,dNetIncome;
    int m,z;
    cout <<"请输入本月大于3500的收入总额=";
    cin>>dsalary;
    m=dsalary-3500;
    if(m>0)
    {
        if(m>80000)
            dtex=m*0.45-13505;
        else
        {
            z=(m<1500)+(m<4500)+(m<9000)+(m<35000)+(m<55000)+(m<80000);
            switch(z)
            {
            case 6:
                dtex=m*0.03-0;
                break;
            case 5:
                dtex=m*0.1-105;
                break;
            case 4:
                dtex=m*0.2-555;
                break;
            case 3:
                dtex=m*0.25-1005;
                break;
            case 2:
                dtex=m*0.3-2755;
                break;
            case 1:
                dtex=m*0.35-5505;
                break;
            default:
                cout<<"error"<<endl;
            }
        }
    }
    else
        dtex=0;

    dNetIncome=dsalary-dtex;
    cout <<"税后收入"<<dNetIncome<<endl;
    cout <<"个人所得税"<<dtex<<endl;
    return 0;
}
