存储对变量数组所做的更改
我正在将程序的玩家位置存储到存储为全局变量的数组中，其中一个示例是：
float motor1[] = {4.312, 27.312};
每当进行移动时，我都有名为 checkposition、moveplayer 和 updateposition 的函数来检索和更新此数组。所有这些函数都位于一个名为 motor.c 的模块中，并且具有执行它们的层次结构。我有一个主模块 main.c，它调用该模块并向其传递一些信息，然后 motor.c 对其进行处理，然后给出答案。让我困惑的是，既然数组被保存为全局变量，这是否意味着每次调用该模块时都会初始化它？这意味着我的更新位置功能永远不会在第一步之后起作用。
I am storing the positions of players for a program i am writing to arrays stored as global variables, an example of which is:
float motor1[] = {4.312, 27.312};
Any time a move is made, I have functions called checkposition, move player and update position that retrieve and update this array. All of these functions are in one module called motor.c and have a hierarchy in which they are performed. I have a main module main.c which calls on this module and passes it some information and the motor.c processes it and then spits out an answer. The thing that confuses me is that since the array is saved as a global variable does that mean that it is initialized every time this module is called? Which would mean that my update position function would never work beyond the first move.

不，如果它是全局变量，它只会在程序启动时初始化一次。
No, if it's a global variable, it gets initialized just once, on program startup.
不，全局变量在程序启动时初始化（并且只有在那时）
No, a global variable is initialized when the program start up (and only then)
