Question

错误：＆＃34; WeatherForecaster的原型:: WeatherForecaster（std ::所有变量）与WeatherForecaster中的任何类都不匹配＆＃34; 我没有关于如何避免这种情况的想法。我的主要代码与错误btw无关。

最近的错误，其余是固定的。我现在在main＆＃34;没有匹配的函数中得到错误来调用WeatherForecast :: WeatherForecast（）＆＃34;。在我创建变量wf WeatherForecast之后。

来源：

#include "WeatherForecaster.h" //header being included
#include<iostream>
using namespace std;

//error comes here 
WeatherForecaster::WeatherForecaster(string d, string fd, int h, int l,      
int hum,int avgw, string avgwd, int maxw, string maxwd, double p)
{

string day=d;
string forecastDay=fd;
int highTemp=h;
int lowTemp =l;
int humidity=hum;
int avgWind= avgw;
string avgWindDir=avgwd;
int maxWind=maxw;
string maxWindDir= maxwd;
double recip=p;
}
WeatherForecaster::~WeatherForecaster(){

    //dtor
};//end of block of source code

标题：我犯了这么简单的错误，我只是不确定它究竟是什么。

#ifndef WEATHERFORECASTER_H
#define WEATHERFORECASTER_H

#include <iostream>
using namespace std;

//does my code have a problem with how it interacts with this struct?
struct ForecastDay{
std::string day;
std::string forecastDay;
int highTemp;
int lowTemp;
int humidity;
int avgWind;
std::string avgWindDir;
int maxWind;
std::string maxWindDir;
double precip;

};

Answer 1

构造函数的声明在标题中采用这些参数（字符串d，字符串fd，int h，int l，int hum，int avgw，string avgwd，int maxw，string maxwd，double p）在哪里？

Answer 2

正如错误消息所述：你需要为＆＃34; WeatherForecaster添加原型（字符串d，字符串fd，int h，int l，int hum，int avgw，string avgwd，int maxw，string maxwd，double p）＆＃34;在你的WeatherForecaster课程中。

需要帮助使用源代码C ++识别问题（标题，结构，类复杂）
