Seems you forgot to install the FrenChPP++ package. After a successful installation (you will need to compile FrenChPP++ on a standard c++ compiler if there are no binary packages for your system (we at the Unauthorized Frog recommend using g++ for this, but feel free to use clang too, but ignore the warnings)) you will need to create a new project, and just copy paste this into the newly created principal.fcpp file. Then upon execution the FrenChPP++ precompiler (which works very similarly to the way Qt handles its signals/slot mechanism) will parse all .fcpp files and will "translate" the .fcpp into valid .cpp and then compile them using your system default compiler.

在c++(或C)程序中不能使用法语关键字。你应该编写代码

 #include <iostream>
 //  ^^^  the english word "include" 

同样的

 return EXIT_SUCCESS;

当然，代码int main(int argc, char**argv)等…

(谢谢你愚人节的玩笑!)

我正在编译这个非常基本的程序。

这不是一个BASIC程序，所以Visual Studio不知道用它做什么。

此外，在法语系统上，需要将程序传递给编译器。

之前的答案几乎涵盖了所有内容，但如果我可以补充一句:

renvoyer SORTIE_SUCCÈS ; // correct, but bad pratice

这当然是允许的，但以下通常是首选:

capitulation ; // a better, frenchier approach

你好，轻跑进入轨道，

我要强调的是，即使您遵循了这里给出的所有答案，由于标点符号的存在，您的程序仍然无法编译。在法语中，分号前面有一个不间断的空格。

我建议以下几点:

#inclure <esflux>

ent principal(ent narg, cara** marg)  // entier, nombre d'arguments, valeur des arguments
{
   std::cendehors << "Bonjour le monde !\n" ;
   renvoyer SORTIE_SUCCÈS ;
}

请注意，我把argn改成了narg，因为它在法语中更自然(尽管与匈牙利符号无关)!
