在 C++ 中的 struct 中初始化 char* [英] Initializing a char* in struct in C++

问题描述

我有一个结构如下:

struct temp 
{
    char* person;
    char* address;
    int id;
    int phone;
}

我有一个结构变量

temp var;

我希望在构造函数中初始化结构的成员，例如:

I wish to initialize the member of the structs in a constructor like:

 Data ( )
{
    var -> person = {};
    var -> address = {};
    var.id = 0;
    var.phone = 0;
 .............. 
}

person 和 address 是字符数组.

person and address are char arrays.

我不确定这是否是在 C++ 中初始化它们的正确方法.有什么建议吗?

I am not sure if that is the correct way to initialize them in C++. Any suggestions ?

推荐答案

我会简单地将它们设置为 NULL.附带说明一下，我不禁注意到你有 var-> 和 var.混合.如果你创建一个对象，它是 [.] 如果你引用一个指向基对象的指针，它是 [->].

I would simply set them to NULL. On a side note, I couldn't help but notice you had var-> and var. mixed. If you create an object, it is [.] If you are referencing a pointer to the base object it is [->].

typedef struct TTEMP 
{
    char* person;
    char* address;
    int id;
    int phone;
}TTemp;

Data ( )
{
    TTemp var;
    var.person = NULL;
    var.address = NULL;
    var.id = 0;
    var.phone = 0;
    .............. 
}
