例如,可以让import std;和#include <math.h>在同一文件中。 只是不要包含 C++ 标准库版本<cmath>。 2 实验 2.1 环境 目前仅MSVC支持import std; C++ compiler support - cppreference.com 实验版本:MSVC 14.40.33807 2.2 正常情况 main.ixx: import std; import MyModule; int main() { std::cout <<...

import std; using namespace std; int main(){ cout<<"Hello\n"; } MSVC显示: [build] main.cpp(1,11): error C2230: Could not find module "std" [build] main.cpp(5,5): error C2065: "cout" : Undeclared identifier 我可以使用复制%VCToolsInstallDir\modules\std.ixx到项目文件夹,并将st...
在Visual Studio 17.6.0版本中，这变得非常简单。简单地设置CMAKE_CXX_STANDARD使用C++23：

The std.compat module makes it easier to work with codebases that refer to many C runtime functions/types in the global namespace.The compiler imports the entire standard library when you use import std; or import std.compat; and does it faster than bringing in a single header file. It'...
#include <string> import std; int main() { std::print("out: {}", "hello"); } Attempting to compile it with 14.39.33218 (latest preview) gives: main.cpp(6,34): fatal error C1907: unable to recover from previous error(s); stopping compilation C:\Program Files\Microsoft...

通过Cython,我们可以轻松地在Python中导入和执行C代码,实现Python与C的互操作。 方法二:使用ctypes 除了Cython,我们还可以使用Python标准库中的ctypes模块来加载动态链接库并调用其中的C++函数。 假设我们有一个C++文件example.cpp,内容如下: // example.cpp#include<iostream>extern"C"{voidgreet(){std::cout<<"He...
