重新定義？

Question

我正在試圖製作一個發生在醫院的小遊戲。下面的代碼：

第一頭：

#ifndef Hospital_Patient_h 
#define Hospital_Patient_h 

class Patient 
{ 
public: 
    Patient(); 
    bool cured(); 
    bool died(); 
    bool treatable(); 
    void treat(); 
    void untreated(); 
    char consonant(); 
    char vowel(); 
    std::string getName(); 


    int age; 
    int health; 
    std::string name; 

    bool operator==(const Patient &other)const; 


}; 
#endif 

和這裏的CPP：

#include <iostream> 
#include <string> 
#include "Patient.h" 
using namespace std; 

char CONSONANTS[] = 
{'b','c','d','f','g','h','j','k','l','m','n','p','r','s','t','v','z', '\0'}; 
char VOWELS[] = 
{'a','e','i','o','u', '\0'}; 
//generates a patient with initial health, a name, and an age from 10-79 
Patient::Patient() 
{ 
    int a= rand() % 80 + 10; 
    health= 50; 
    name= getName(); 
    age= a; 
} 

bool Patient::cured() { 
    return health >= 100; 
} 

bool Patient::died() { 
    return health <= 0; 
} 
//treatable if not dead and not cured 
bool Patient::treatable() { 
    return !died() && !cured(); 
} 

void Patient::treat() { 
    if(treatable()) health= min(health + 10, 100); 
} 

void Patient::untreated() { 
    if(treatable()) health= max(health - 1, 0); 
} 

char Patient::consonant() 
{ 
    int index = rand() % 17; //CONSONANTS.size(); 
    return CONSONANTS[index];//rand.nextInt(CONSONANTS.length)]; 
} 

char Patient::vowel() 
{ 
    int index = rand() % 5; //VOWELS.size(); 
    return VOWELS[index];//rand.nextInt(VOWELS.length)]; 
} 

//generate a random name 
string Patient::getName(){ 
    string s; 
    s+=toupper(consonant()); 
    s+= vowel(); 
    s+=consonant(); 
    s+=vowel(); 
    if (rand() % 3 == 0) { 
     s+=consonant(); 
    } 
    if (rand() % 3 == 0) { 
     s+=consonant(); 
     s+=vowel(); 
    } 
    s+=(' '); 
    s+=toupper(consonant()); 
    s+=vowel(); 
    if (rand() % 3 == 0) { 
     s+=consonant(); 
    } 
    s+=consonant(); 
    s+=vowel(); 
    if (rand() % 3 == 0) { 
     s+=consonant(); 
    } 
    if (rand() % 3 == 0) { 
     s+=consonant(); 
     s+=vowel(); 
    } 
    return s; 
} 
//overload == 
bool Patient::operator==(const Patient &other)const{ 
    //compare each room's room number field 
    return (this->age == other.age && this->name == other.name); 
} 

每個我得到一個錯誤說「功能名」

的重新定義功能後至今

我也遇到了構造函數的問題，併爲頭文件中定義的變量賦值。標題也不喜歡std ::出於某種原因，我知道我不應該在標題中使用名稱空間。

Answer 1

嘗試將#include <string>添加到Patient.h最頂端。當我這樣做時它爲我編譯。

Answer 2

只是一個預感，您已將Patient.cpp而不是Patient.h包含在您的某個文件中。
