Новый студент ... слишком много аргументов

Question

Я получаю эту ошибку при попытке запустить этот код и не знаю почему. Любая помощь приветствуется ... Я новичок. 71 42 [Ошибка] слишком много аргументов для функции 'void summary()' Это для класса C++, и я не знаю, что я делаю неправильно.

Answer 1

Прототип вашей функции не имеет аргументов:

void summary(); 

Оно должно быть:

void summary(std::string, std::string, std::string, std::string);
