If you want to compile and link a standard C++ program with "cl" command tool, you can follow this tutorial:

1. Create a simple C++ program, Hello.cpp, with a text editor:

#include <iostream>  
using namespace std;  
void main() {  
    cout << "Hello, world, from Visual C++!" << endl;  
}

2. Run "All Programs > Visual Studio 2017 > Visual Studio Tools > Developer Command Prompt for VS 2017". You see the Visual Studio Command Prompt window.

3. Compile and link the C++ program:

C:\fyicenter>cl Hello.cpp
