c语言拼图游戏-PicturePuzzle2023年6月22日 ​
开发环境：使用vs2019，配合easyx图形库
基本设计：
注意，需要自行（寻找并）添加图片，
在例子中，使用原神角色 甘雨进行游戏。
struct Block结构体：每个方块，都有坐标，以及对应的图片， 所以起码需要col，row，imgIdx。init函数：然后使用easyx，初始化图片对象，，加载图片等。
paint函数：使用col得到y坐标，使用row得到x坐标，使用imgIdx得到确定图片，直接进行绘制图片，在程序中，增加了线，用于区分每个block。
userInput函数：使用easyx图形库，确定点击的坐标（x，y），
左击时，，，根据y得到col，根据x得到row，判断四个方向是否有空缺（注意防止越界），如果有空缺，交换两者的imgIdx，从而完成图片交换。
当完成游戏时，右击可重新开始游戏。checkWin函数：检查block的imgidx是否有序即可。
拓展功能：
为了保证能完成拼图，打乱时，需要保证逆序数是偶数，两个循环比较一下即可。
