100分,如何把delphi的程序转为C++的? ( 积分: 100 )

我有一个用delphi5做好的程序,有原代码,不知道如何可以把它转为C++的?

我有一个用delphi5做好的程序,有原代码,不知道如何可以把它转为C++的?

需要自己慢慢慢慢翻译,可以去找找pascal to c 这样的工具.
为什么不做成DLL呢?

在你的程序中一般情况下用stdcall声明所有函数就可以了
好象是吧

to :余远源
因为有人向我要程序的C++原代码,他需要有些改动.
pascal to c 这样的工具在那里可以找到?我今天已经搜索了一下,没有找到.
我对C++不是很了解啊~~~~
to :keyi2323 "在你的程序中一般情况下用stdcall声明所有函数就可以了",
可以详细些吗?我不清楚!

我把source贴上,大家研究下:

就是要把上面的代码翻译过来
