但是重新编译,会出下面警告 J:\workspace\codemgr\cmimpl\testmd5.cpp: In function ‘int main()’: J:\workspace\codemgr\cmimpl\testmd5.cpp:26:11: warning: extended initializer lists only available with -std=c++11 or -std=gnu++11 test(_stA{str,0,1}); 它的意思大概就是_stA{str,0,1}这...
Initialization Lists: Summary Before the body of the constructor is run, all of the constructors for its parent class and then for its fields are invoked. By default, the no-argument constructors are invoked. Initialization lists allow you to choose which constructor is called and what ...

Accessing constructors inside decltype statements The following code now produces C2248: 'S::S': cannot access private member declared in class 'S': C++ Copy class S { S(); public: int i; }; class S2 { auto f() -> decltype(S().i); }; To fix the error, add a friend decla...
对定制的 “类型转换函数” 保持警觉(单自变量 constructors 可通过简易法(explicit 关键字)或代理类(proxy classes)来避免编译器误用;隐式类型转换操作符可改为显式的 member function 来避免非预期行为) 区别increment/decrement 操作符的前置(prefix)和后置(postfix)形式(前置式累加后取出,返回一个 reference;后置...

Here is a simple example of a POINT structure, which contains two integers named x and y, and also shows how to initialize a structure in the constructor: from ctypes import * class POINT(Structure): ...fields= [("x", c_int), ...
