c++ - 构造函数语法周围的括号

Question

12.1/1. Constructors do not have names. A special declarator syntax using an optional sequence of function-specifiers (7.1.2) followed by the constructor’s class name followed by a parameter list is used to declare or define the constructor. In such a declaration, optional parentheses around the constructor class name are ignored.

阅读该文本，我想知道在以下示例中被忽略的构造函数名称周围的括号是什么？

class MyClass
{
    MyClass();
};

MyClass::MyClass() {
}

Answer 1

您的代码片段中没有可选的括号。以下示例在构造函数类名周围有可选括号，这些括号将被忽略:

class MyClass
{
    (MyClass)();
};

MyClass::MyClass() { }
