在线C++编译器介绍原文：http://blogs.msdn.com/xiangfan/archive/2008/08/29/online-c-compilation-service.aspx网上有许多在线C++编译器。你可以利用它们对你的代码针对各种C++编译器进行兼容性测试，而不需要购买和安装这些编译器。下面的网址是最有名的两个在线C++编译网站：http://www.dinkumware.com 阅读详情

VS2008编译上面代码时出现
1>d:\vc++工作文件夹\my_dx\momogame.h(23) : error C4430: 缺少类型说明符 - 假定为 int。注意: C++ 不支持默认 int
1>d:\vc++工作文件夹\my_dx\momogame.h(23) : error C2143: 语法错误 : 缺少“,”(在“*”的前面)
1>d:\vc++工作文件夹\my_dx\load.cpp(4) : error C2244: “CountWndPos”: 无法将函数定义与现有的声明匹配
1> d:\vc++工作文件夹\my_dx\load.cpp(3) : 参见“CountWndPos”的声明
1>d:\vc++工作文件夹\my_dx\load.cpp(4) : fatal error C1903: 无法从以前的错误中恢复；正在停止编译

其中Wnd声明在momogame.h,CountWndPos实现在load.cpp,看半天看不懂哪里错了，望高手指导！！

PLC编程进阶：结构体(UDT)与功能块(FB)的模块化实践指南本文深入探讨了PLC编程中实现模块化的核心方法，重点解析了结构体(UDT)与功能块(FB)的协同应用。通过将零散数据封装为UDT，并将控制逻辑打包为可复用的FB，能够构建出结构清晰、易于维护和调试的PLC程序。文章结合拧紧枪、电机控制等实战案例，提供了从设计原则到分层架构的完整实践指南，旨在帮助工程师将混乱的‘面条式’代码改造为高效的‘正规军’。阅读详情

你仔细看看，声明和定义都有了，它是一个抽象类

GameWindow这个类的声明在哪里呢？

最主要是不明白为什么会出现这样的语法错误:
error C2143: 语法错误 : 缺少“,”(在“*”的前面)

总算解决了，不过这是不是说我要把所有类得声明都要放在模块的前面呢？
class one;
class two;
.......
namespace one;
namespace two;
....
那样总觉得很别扭
