指向靜態的指針

Question

類Student有一個靜態成員Year這是一個指向std::string的指針，指向動態分配的數組。

ERROR: Cannot convert 'const char*' to 'std::string*' in initialization 

爲什麼我得到錯誤：

class Student 
{ 
private: 
    string name; 
    int year; 
    string semester; 
    int AmtClass; 
    static string *Year[4]; 

    //Skipping the public members 
}; 

string *Student::Year[4] = { "Freshman", "Sophomore", "Junior", "senior" }; 

問題時試圖初始化Year發生？

Answer 1

struct A 
{ 
    static std::string *cohort; 
}; 

std::string * A::cohort = new std::string[4]; 

目前尚不清楚爲什麼要動態分配數組。你可以使用 std::array<std::string, 4>或std::dynarray<std::string>

當你更新你的帖子，然後任你應該寫

std::string * Student::Year = new std::string[4] { "Freshman", "Sophomore", "Junior", "senior" }; 

或者

struct Student 
{ 
    static std::string Year[]; 
}; 


std::string Student::Year[4] = { "Freshman", "Sophomore", "Junior", "senior" };
