如何初始化作为类成员的数组？ [英] How to initialize an array that is a member of a class?

问题描述

例如我有一个类叫DeckOfCards和数组char * suit [4]。

For example I have a class called DeckOfCards and array char *suit[ 4 ].

class DeckOfCards
{
public:
    // some stuff

private:
    char *suit[ 4 ];
};

我可以用这种方式初始化这个数组？ char * suit [4] = {Hearts，Diamonds，Clubs，Spades} 我想可以使用构造函数，

Where I can initialize this array in such a way? char *suit[ 4 ] = { "Hearts", "Diamonds", "Clubs", "Spades" } I guess it can be done using constructor, but I don't know how exactly to do it.

推荐答案

您可以在类中创建一个静态变量，如下所示：

You could create it as a static variable in the class, like this:

class DeckOfCards
{
public:
  DeckOfCards() {
    printf("%s\n", suit[0]);
  }

private:
  static const char *suit[];
};

const char *DeckOfCards::suit[] = { "Hearts", "Diamonds", "Clubs", "Spades" };

int main(void)
{
  DeckOfCards deck;
  return 0;
}
