函数已经有一个函数体

Error C2084 Function already has a body

本文关键字：函数体 有一个 函数      更新时间：2023-10-16

我在整个网站都看到了这个问题，但仍然没有任何东西能够解决我的问题。这是我唯一的错误，我不知道如何解决这个问题。我试过注释掉代码的不同部分，只是想看看会发生什么，但除了错误之外什么都没有。发生了什么事?

这也是构建错误

错误C2084:函数'HeroProfile::HeroProfile(void)'已经有body

Main.cpp 

#include <iostream>
#include <string>
#include "HeroProfile.h"
using namespace std;
int main()
{
string name;
int race;
double weight;
    cout << "Enter your Hero's name:";
cin>> name;
cout << "Enter your Hero's Race (1:Elf 2:Human 3 Dwarf)";
cin >> race;
cout << "Enters your Hero's weight ( in pounds):";
cin >> weight;
HeroProfile Hero_1(name, race, weight);
cout << endl << "hero's Name: " << Hero_1.getName() << endl <<
    "Race: " << Hero_1.getRace() << endl <<
    "Weight:" << Hero_1.getWeight() << endl;
cout << endl;
cout << "Enter your Hero's Name:";
cin >> name;
cout << "Enter your Race (1:Elf 2:Human 3 Dwarf)";
cin >> race;
cout <<"Enter your Hero's weight (in pounds)";
cin >> weight;
HeroProfile Hero_2(name, race, weight);
Hero_2.setName(name);
Hero_2.setRace(race);
Hero_2.setWeight(weight);
cout << endl << "Hero's Name: " << Hero_2.getName() << endl <<
    "Race: " << Hero_2.getRace() << endl << "Weight: " << Hero_2.getWeight() <<     endl;
return 0;
}

头文件

#include <iostream>
#include <string>
using namespace std;
#ifndef HeroProfiel_H 
#define HeroProfile_H
class HeroProfile 
{
public:
    //default constructor
    HeroProfile();
    //overlaod constructor
    HeroProfile(string, int, double);
    //destructor
    ~HeroProfile();
    //Accesor functions
    string getName() const;
        // get name - returns name of patient
    int getRace() const;
        // getHeight-returns height of patient
    double getWeight() const;
        // getWeight- returns weight of patient
    //Mutator Functions
    void setName(string);
        //set name of patient
        //@param string - name of patient
    void setRace(int);
        //setHeight-sets heigh tof patient
        //@param int- height iof patient
    void setWeight(double);
    //setWeight-sets weight of patiend
    //@param double-weight of patient

private:
    //Memeber variables
    string newName;
    int newRace;
    double newWeight;


};
#endif

和第二个。cpp文件

#include "HeroProfile.h"
eroProfile::HeroProfile() //Default constructor
{
newRace = 0;
newWeight = 0.0;
}
HeroProfile::HeroProfile(string name, int race, double weight) //Overloaded Constructor
{
newName = name;
newRace = race;
newWeight = weight;
}
HeroProfile::HeroProfile()
}
}
//Accessors
string HeroProfile::getName() const 
{
return newName;
}
int HeroProfile::getRace() const 
{
return newRace;
}
double HeroProfile::getWeight() const
{
return newWeight;
}
//Mutators
void HeroProfile::setName(string name)
{ 
newName = name;
}
void HeroProfile::setRace(int race)
{
newRace = race;
}

void HeroProfile::setWeight(double weight)
{
newWeight = weight;
}

正如其他人所注意到的，您在第二个cpp文件中为HeroProfile默认构造函数HeroProfile::HeroProfile()定义了两个定义:

第一个是

HeroProfile::HeroProfile() //Default constructor
{
newRace = 0;
newWeight = 0.0;
}

第二个是

HeroProfile::HeroProfile()
}
}

基于我没有看到的事实，您可能打算将第二个作为您的类析构函数(在您的头文件中声明，但未在您的cpp文件中定义)，在这种情况下，您应该将其替换为:

HeroProfile::~HeroProfile()
}
}

我希望你没有被HeroProfile::HeroProfile(void)和HeroProfile::HeroProfile()是同一个东西的事实弄糊涂，所以我想我应该指出来。

消息的意思就是它所说的。忽略输入错误，第二个.cpp中的第一个和第三个定义是针对同一个函数的。
