c - 数组中没有出现的字母（出现奇怪的字符）-C编程

问题描述

我正在创建一个游戏，光标'@'在棋盘上移动（二维数组）

所以我需要包含一个结构作为我的大学指南的一部分，但我不知道如何在结构中从 AZ (char) 分配一个字母数组，所以我做了手动方式，但由于某种原因，当我打印出数组，它显示了一些随机符号:'(

还有什么方法可以让我将控件（WASD）放入一个函数中？我试图发挥作用，但由于某种原因，“@”没有移动

我附上了一张关于我跑步时的样子的图片，以及它的样子。（忘记点和等号，它们与制作板的设计相同）

我的代码：

#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <time.h>
#include <conio.h>

struct game{

char name[25], input, arr[10][10];
int x, y, c,d, m , n, count, countalpha;

};

解决方案

您struct game按值将 传递给函数，这意味着它们对副本进行操作。struct game gamecp因此，main永远不会初始化“原始” 。而是通过引用传递（作为struct game *指针参数）。
