How to make command passing from C++ code to console?

Question

Qt

Hello everybody!
It became interesting how the process could be organized.
There is some executable file that performs some functions.
Let's say the user selects some file, selects some options. It then chooses a new filename and destination folder.
Question! How to pass all this data to the console? Those. pass a command like "executable_file_name option1 option2 input_file output_file".
(Development is in C++/Qt under windows)
Thank you for your attention!

system("имя_исполняемого_файла опция1 опция2 входной_файл выходной_файл");

#include <sstream>
...
{
   std::stringstream st;
   int i=9000;
   std::string str_param="value";
   st<<"command "<<i<<" " << str_param;
   system(st.str().c_str());
}
