如果满足嵌套条件，则计算结果不显示结果C ++

Question

我希望该计划能够显示1,2,3年的年度加薪。

用户输入年份 用户输入annualSalary，

然后如果条件为真，则计算如下。

但是，当我运行时，它没有显示我输入的任何给定年份的计算。为什么？我回去几次，试图确定我失踪了什么？

#include "stdafx.h"
#include <iomanip>
#include<iostream>
using namespace std;

int main()
{
    double annualSalary = 0; 
    int year = 0;
    double rate3 = 0.03; 
    double rate4 = 0.04; 
    double rate5 = 0.05; 
    double rate6 = 0.06;  
    double annualRaise = 0; 


    cout << fixed << setprecision(0); 

    cout << "enter current year (1 to 3) ";
    cin >> year;
    cout << "enter annual Salary";
    cin >> annualSalary; 


    if (year = 1)
        annualRaise = annualSalary * rate3;
    else if
        (year = 2)
        annualRaise = annualSalary * rate4;
    else if
        (year = 3)
        annualRaise = annualSalary * rate5; 

    return 0;
}

您需要添加打印if (year == 1) { annualRaise = annualSalary * rate3; cout << "Salary : " << annualRaise << endl; // output the value } else if(year == 2) { annualRaise = annualSalary * rate4; cout << "Salary : " << annualRaise << endl; // output the value } else if(year == 3) { annualRaise = annualSalary * rate5; cout << "Salary : " << annualRaise << endl; // output the value } system("Pause"); //To be able to keep the console window open 以查看您的工作结果：

Private Sub FWHM_Click(sender As Object, e As EventArgs) Handles FWHM.Click
    Dim pythonProcess As New Process()
    Dim arg1 As New Integer
    arg1 = 1
    With pythonProcess
        .StartInfo.FileName = "pythonw.exe"
        .StartInfo.WorkingDirectory = "C:\Users\...\"
        .StartInfo.Arguments = ("HelloWorld.py" & arg1)
        .StartInfo.RedirectStandardOutput = True
        .StartInfo.UseShellExecute = False
        .StartInfo.CreateNoWindow = True
        .Start()
    End With
End Sub

使用==比较=并添加cout以查看结果。

if (year == 1)
        annualRaise = annualSalary * rate3;
    else if
        (year == 2)
        annualRaise = annualSalary * rate4;
    else if
        (year == 3)
        annualRaise = annualSalary * rate5;

cout << annualRaise;
