如何添加可以在我的生命游戏程序中获取生成的功能? [英] How do I add a feature where I can get the generation in my game of life program?
本文介绍了如何添加可以在我的生命游戏程序中获取生成的功能?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试让我的程序在单元格更改其形式的每个步骤中显示(首先在控制台中测试)计数.因此，计数应该从 0 开始，并在每次单元格更改其形式时递增.我试过这个，使用count++但是它不会增加1，而是给我随机数.任何帮助都感激不尽.
