How i could print n number of parameters of any data type to a debug?-CodePudding

I know of the WINAPI OutputDebugString(L"");

How I could go with a function able to receive n number of parameters which any data type, and print the value to a debug?

By debug I mean a window similar of the Visual Studio Output.

CodePudding user response：

This can be achieved with a template:

   #include <utility>
   #include <iomanip>
   #include <sstream>

    template <typename Arg, typename... Args>
    void Print(Arg&& arg, Args&&... args)
    {
        std::stringstream ss;
    
        ss<< std::forward<Arg>(arg);
        using expander = int[];
        (void)expander {
            0, (void(out << std::forward<Args>(args)), 0)...
        };
    
        OutputDebugStringA(ss.str().c_str());
    }
    
    
    int _tmain(int argc, _TCHAR* argv[])
    {
    
        Print( 1, "abcde", 2, 3, "foo");
    }
