У меня вопрос не только к экрану, мне также нужно распечатать / вывести результат в текстовый файл.
Обычно я могу сделать что-то вроде этого:
outstream outfile;
outfile.open ("testOutput.txt", ios :: out);
outfile << firstName << ""; </p>
Но как в этом случае получить функции печати void (встроенные в классы), напечатанные в текстовом файле?
