从文件中读取代码 [英] Reading code from a file
问题描述
我要做的是创建一个非常基本的A-life模拟器。
我无法弄清楚如何从
读取和执行C ++代码
文件，如果我能做到这一点就可以很容易地制作自定义文件或
让主程序制作它们。
任何帮助都将不胜感激。
What I am trying to do is to create a very basic A-life simulator.
What I can''t figure out is how to read and execute C++ code from a
file, if I could do this it would be simple to make custom files or
have the main program make them.
Any help would be appreciated.

你的意思是用c ++代码加载外部文件并在主应用程序的
内执行它们。那么你需要一个c ++解释器，
或者你必须先编译它们然后再执行。我认为
如果你需要这种功能，你会更好地使用其他更高级的语言。

You mean load external files with c++ code and execute them within
your main application. Then you either need a c++ interpreter,
or you have to compile them first and then execute. I think
you''re better of with some other higher language if you
need this kind of functionality.

我无法想象out是如何从
文件中读取和执行C ++代码，如果我能做到这一点，那么制作自定义文件会很简单，或者主程序会生成它们。

只需编译它，[检查输出]，然后使用''system（）''运行它。
[未经测试。只是为了一个想法。 ]
std :: string comp（" g ++"）;
std :: string cpplibs（" -lmylib"）;
std :: string cppfile（" MyFile.cpp"）;
std :: string Command =" \"" + comp + cppfile + cpplibs +" \"" ;;
system（Command）;
//在这里查看
系统（MyFile）;
获取某些IDE的源代码，并检查它们是如何实现的。

Just compile it, [check output], and run it using ''system()''.
[ untested. just for an idea. ]
std::string comp( "g++ " );
std::string cpplibs( "-lmylib " );
std::string cppfile( "MyFile.cpp " );
std::string Command = "\"" + comp + cppfile + cpplibs + "\"";
system( Command );
// check it here
system( MyFile );
Get the source for some IDE, and examine how they do it.

你能解释一下吗？这可能正是我所需要的。
只是为了清理我需要的东西：
我需要它动态的主程序（在运行时） genarate代码。
我能看到的唯一方法就是（拥有程序）
将其写入文件然后在以后加载。
我需要能够创建和运行大量文件，而不必为每个文件加载机制编码。
Can you explain that a bit more? It might be just what I need.
Just to clear up what I need it for:
I need it the main program to dynamically (At runtime) genarate code.
The only way I can see for this to be done is to (have the program)
write it to a file then load it back at a later time.
I need to be able to create and run a large number of files without
having to code in a loading mechanism for each one.
这篇关于从文件中读取代码的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
