如何编写数组的setter和getter? (C ++) [英] How do I write setters and getters for an array? (c++)

问题描述

我正在用C ++写一个类，但是我不确定如何为数组创建setter和getter(很抱歉，这是一个基本问题！)，我收到以下错误:

Im writing a class within c++, however I am not certain on how to create the setters and getters for the arrays (sorry for it being a basic question!) I am getting the following error:

在']'标记之前的预期主要表达式

expected primary expression before ']' token

这是我的代码:

Class planet: public body
{
private:
  string name[];
  string star[];
public:
  void nameSetter (string h_name[])
  {
      name[] = h_name[];
  }
};

对于这个愚蠢的问题，我再次感到抱歉，我知道我没有传递索引，但是，当我创建索引时，它会引发大量错误！

Once again I am sorry for such I silly question, I know I am not passing an index through, however, when I create an index it throws up a large amount of errors!

推荐答案

string name[];

这不是数组，而是一个指针.使用vectors代替:

This is not an array, it is a pointer. Use vectors instead:

#include <vector>
class planet: public body
{
private:
  vector<string> name;
  vector<string> star;
public:
  void nameSetter (const vector<string> &h_name)
  {
      name = h_name;
  }
};
