конфликтный тип возвращаемого значения для Init()

Question

У меня есть MasterProcess, который является специализацией общей концепции процесса, а класс MasterDocument должен рассматривать несколько разных специализаций MasterProcess в возможном общем виде. Я использую Я использую virtual void Init() для достижения этой функциональности. Код выглядит следующим образом:

#include <iostream>

Answer 1

Я думаю, вы пытаетесь предоставить конструктор для класса ConcreteMasterProcess2. Вы должны сделать это так:

class ConcreteMasterProcess2 : public BaseMasterProcess { 
public: 
    ConcreteMasterProcess2() { 
     /* ... */ 
    } 
}; 

Answer 2

Ваш метод Init в ConcreteMasterProcess1 не имеет указанного типа возврата. Возможно, вы смешиваете его с конструктором.
