错误：表达式必须具有类类型 [英] error: expression must have a class type

问题描述

我得到一个错误：表达式必须具有类类型
首先，我不明白为什么会出现此错误。我创建并反对并使用它。
在我的main中：

I get the error: expression must have a class type Firstly, I don't understand why I am getting this error. I create and object and use it. in my main:

#include "Worker.h"

int main()
{

    Worker myWorker();
    myWorker.inputInfo();
    myWorker.displayPayBarGraph();

}

Worker.h

//Worker.h
//Definition of class Workers
//Member functions are defined in Worker.cpp


//Worker class defintion 

class Worker
{
public:
    Worker();               //constructor initializes worker type

    void inputInfo();           //attains worker information
    void displayPayBarGraph();  //prints a bar graph representation of the pay

private:

    int workerCode;     //worker type
    //PAY FOR EACH WORKER
    double code1pay;            //manager
    double code2pay;            //hourly workers
    double code3pay;            //commission workrs
    double code4pay;            //pieceworkers

    int hourlyWorkerPay(double, int);   //returns the pay of hourly workers
    int commissionPay(int);     //returns the commission workers pay
    int pieceWorkerPay(int, int);   //returns the pieceworkers pay
};

推荐答案

最烦人的解析器：

此行：

Worker myWorker();

声明一个函数，不带任何参数并返回一个工作者。

declares a function taking no parameters and returning a Worker.

只需声明您的对象：

Worker myWorker;
