沒有適當的默認構造函數可用 - 默認構造函數調用的地方在哪裏？

Question

編譯下面的代碼我在105行得到這個error C2512: 'PayOffBridge': no appropriate default constructor available

我的問題是：默認的構造函數被調用？我該如何解決它？

Answer 1

VanillaOption(const VanillaOption& original)沒有初始化列表，這意味着成員必須是缺省構造。讓它

VanillaOption::VanillaOption(const VanillaOption& original) 
    : Expiry(original.GetExpiry()), 
    ThePayOffBridge(original.ThePayOffBridge) 
{}
