C ++迭代结构 [英] C++ iterating a struct

问题描述

是否可以遍历结构？

例如

struct team{
   int player1;
   int player2;
   int player3;
   int player4;
   ...
   int player99; 
   int size = 99;
}

然后运行for循环设置或访问foo 1-4？

then run a for loop to set or access foo 1-4?

我猜伪代码看起来像

for(int i = 0; i < size; i++){
    player i = (i+1); 
 }

如果没有意义，更简单的解释是我只想要能够无需硬编码player1 = 1即可浏览每个变量; player2 = 2.

A more simplified explanation if that doesnt make sense is I Just want to be able to go through each variable without having to hard code player1 = 1; player2 =2.

推荐答案

一种方法是将玩家/元素放入数组：

One way is to put the players/elements into an array:

struct Team {
    static int const size = 99;
    int players[size];
};

然后：

for(int i = 0; i < size; ++i)
    int player = players[i];
