这里发生了什么？ [英] What is going on here?
问题描述
我已经编程了一段时间，我在
之前看过这个语法，我从一本书中复制了这个，但这本书并没有解释会发生什么。
在这里。
级引擎{
受保护：
静态引擎* pengine;
比以后：
if（initialize（hin））{
if（！engine :: gengine（） - > init（CmdShow ））{return false;}
while（TRUE）{
引擎对象有自己的类型作为指针然后它被称为
由上面的命令。我相信这是OO编程，但我不会理解发生了什么以及我会写什么小程序或
项目tha = t会帮助我学习这个。

多么不幸名字，读起来像企鹅！
比以后：
if（initialize（hin））{
if（！engine :: gengine（） - > init（CmdShow））{return false;}
这将是语法错误，你有宣称pengine作为一个指针
，在这里你试图调用它上面的operation（）。
while（TRUE）{
为什么将伪布尔与bool混合使用？

具体你不明白什么？我不认为你的问题是与bO编程有关，更多的是不理解的情况
一些C ++基础知识。您正在学习哪本书？

< blockquote class =post_quotes>
if（initialize（hin））{
if（！engine :: gengine（） - > init（CmdShow））{return false;}
这是一个语法错误，你声明了pengine作为指针
，在这里你试图调用它上面的operation（）。
我根本没看到它在哪里用过pengine。我看到的唯一使用operator（）
的是genngine（）返回 - 而且他还没有向我们展示
。

I have been programming for a while and I have seen this syntax before
and I copied this from a book but the book didn''t explain what is going
on here.
class engine{
protected:
static engine* pengine;
Than later:
if(initialize(hin)){
if(!engine::gengine()->init(CmdShow)){return false;}
while(TRUE){
The engine object has its own kind as a pointer then later it is called
by the above command. I do believe this is OO programming but I don''t
understand what is going on and what small programs I would write or
projects tha=t would help me learn this.

What an unfortunate name, reads like penguin!
Than later:
if(initialize(hin)){
if(!engine::gengine()->init(CmdShow)){return false;}This would be a syntax error, you have declared "pengine" as a pointer
and here you are attempting to invoke operation () on it.
while(TRUE){
Why mix pseudo booleans with bool?

anything to do with OO programming, more an case of not understanding
some C++ basics. Which book are you learning from?

This would be a syntax error, you have declared "pengine" as a pointer
and here you are attempting to invoke operation () on it.I don''t see where it''s used pengine at all. The only use of operator()
that I see is on whatever genengine() returns -- and he hasn''t shown us
that at all.

Oops, see it was an unhelpful name!
