问题描述
为了在C文件中使用C ++代码，我读到我们可以做extern "C" { (where the c++ code goes here)}，但是当我尝试使用cout打印出某些内容时，由于它无法识别库，我一直遇到错误.我想我对extern"C"如何允许您在C中使用C ++代码感到困惑.
In order to use C++ code in a C file, I read that we can just do extern "C" { (where the c++ code goes here)}, but when I try printing something out using cout, I keep getting an error because it does not recognize the library . I think I am just confused on how extern "C" allows you to use C++ code in C.
推荐答案
反之亦然.您可以使用extern C使用C ++编译器添加要编译为C代码的代码.
The opposite is true. You can use extern C to add code you want to compile as C code using a C++ compiler.
除非我缺少您无法使用C编译器编译C ++代码的东西.
Unless I'm missing something you can't compile C++ code with a C compiler.
