You can check out the below code if it suits your need, the txt array sz can be used as a string pointer. I have added code support for both Unicode and MBCS,

            #include 
            #include 

            #ifdef _UNICODE
                #define String std::wstring
            #else
                #define String std::string
            #endif 

            int _tmain(int argc, _TCHAR* argv[])
            {
                TCHAR sz[1024] = {0};
                std::vector allArgs(argv, argv + argc);

                for(unsigned i=1; i < allArgs.size(); i++)
                {
                    TCHAR* ptr = (TCHAR*)allArgs[i].c_str();
                    _stprintf_s(sz, sizeof(sz), _T("%s %s"), sz, ptr);
                }

                return 0;
            }
