intprintf(constchar*format,...);intmain(){printf("I'm learning the use of Extern in C++");} We use theexternkeyword in C++ programming to eliminate this issue. Whenever the C++ compiler finds the code inside theextern "C" {}block, it makes sure that the name of the function remains...
In the previous tutorials, we looked at how to useDockerandGitHub Actions. In this tutorial, we will use both Docker and GitHub Actions along with a new framework, CppUTest, to build a unit test demo for C/C . You can watch this tutorial in video form here: ...
The first step for this is to change the declaration/definition of this function by introducing the notation extern “C”. #include <iostream> extern "C" void func(void) { std::cout<<"\n This is a C++ code\n"; } The next step is to create a library out of the code above. The ...

Variables in C++ are named memory locations that can store different types of data. We can use the variable names to access and manipulate the data.
To associate a delegate with a native function, you must wrap the native function in a managed type and declare the function to be invoked throughPInvoke. C++ // mcppv2_del_to_umnangd_func.cpp// compile with: /clr#pragmaunmanagedextern"C"voidprintf(constchar*, ...);classA{public:stati...
