寻找C ++& java编程的想法 [英] Finding C++ & java idea for programming

问题描述

大家好。

我是c＃programmer（windows窗体）。我开始任何java&几周前的c ++练习。

我觉得可以理解c ++& java因为我知道c＃。

但我的主要问题是用c ++或java编程的想法。

例如我自己说如果我想创建windows表单，我可以通过c＃来做到这一点为什么我使用java或c ++。

我的问题是我可以通过c ++和java做什么类型的项目？游戏编程？桌面编程？物联网？ Web开发？我不知道我应该在c ++或java中使用哪种类型来开始或者使用。

我希望能理解我的意思。



UPDATE ::::::

hi all.
i am c# programmer (windows forms). and i started any java & c++ exercises any weeks ago.
i feel can understand both c++ & java because i know c#.
but my main problem is idea for programming in c++ or java.
for example i say with myself that "if i want to create windows form,i can do it by c# so why i use java or c++".
my problem is what kind type of projects i can do by c++ and java? Game prgramming ? desktop programming? IOT? Web Development? i don't know which type i should start or toturial in c++ or java.
i wish to can understand my mean.

UPDATE::::::

this is not solution . it is continue. really i want to write cross paltform application and great applications. and c# not supported it of course if we not see .net core.
but i like to create great good applications without any limit. and i want to work with c++ & java.
but i don't know that how can i find idea for starting that.
i think i can begin a project by c++ & java and i am not a beginner. because i understand c++ , java syntax and it's principles (according to my studies in this weeks).
and i think can understand more those by write a good project.
totally (I do not know what kind of branch to choose) IOT? WEB? DESKTOP? which today tech?

推荐答案

基本上，你可以用C＃创建的任何东西，你可以用C ++或Java创建（特别是现在Xamarin是Visual Studio的一部分）。

唯一的区别是C ++可用于更广泛的目标处理器和系统池（几乎每个处理器都存在C ++交叉编译器（甚至八位 - 至少有一个Z80 C ++）编译器）其中C＃仅适用于.NET（或equivelant：Mono for Linux，Xamarin for Android / iOS）将运行。

并且Java也可以在C＃不能使用的地方使用 - 只要Java虚拟机在那里运行，所以cn Java代码（包括智能卡： Java（软件平台） - 维基百科 [ ^ ]）



有些地方可以使用C＃，你不能使用Java或C ++ - 例如网站的服务器端代码 - 但在大多数情况下你可以在任何地方使用它们。



只是不要假设我觉得可以理解c ++和java，因为我知道c＃：theay是非常不同的语言共享一些常见的语法，如果你尝试在C ++中做C＃方式的事情，你可能会做一个非常讨厌的应用程序。特别是如果您尝试在本机应用程序中执行此操作：没有CLR，C ++不提供垃圾回收，因此内存释放由程序员决定。



我们不能说对这些项目使用C＃，而对那些项目使用Java / C ++因为没有明确的界限：它们可以在整个项目中互换（但可能不在项目中，如果你不能很好地工作尝试同时使用C＃和Java！）

Basically, pretty much anything you can create in C#, you can create in C++ or Java (especially now Xamarin is part of Visual Studio).
The only difference is that C++ can be used across a wider pool of "target" processors and systems (C++ cross compilers exist for pretty much every processor (even eight bit - there is at least one Z80 C++ compiler) where C# is only available where .NET (or equivelant: Mono for Linux, Xamarin for Android / iOS) will run.
And Java can also be used where C# can't - as long as the Java Virtual Machine runs there, so cn Java code (this includes smartcards: Java (software platform) - Wikipedia[^])

There are places you can use C# that you can't use Java or C++ - the server side code for a website for example - but in most cases you could use any of them anywhere.

Just don't assume "i feel can understand both c++ & java because i know c#": theay are very different languages that share some common syntax, and if you try to do things "the C# way" in C++, you will probably make a very nasty app. Particularly if you try to do it in a native app: without the CLR, C++ does not provide garbage collection, so memory deallocation is up to you the programmer for example.

We can't say "use C# for these projects, but Java / C++ for those" because there is no clear line: they are interchangeable for whole projects (but probably not within a project, it's not going to work too well if you try to use both C# and Java together!)

经验法则：

• 几乎所有事情都使用 C＃。
• 在嵌入式系统上使用 C / C ++ 或非常专业，性能密集的任务（但是你必须掌握它）。
• 使用 Java 放松编码或故意放慢你的申请速度。

Obligatory citation: Abstruse Goose | How to Teach Yourself Programming[^].

Rules of thumb:

• Use C# for almost everything.
• Use C/C++ on embedded systems or very specialized, performance intensive, tasks (however you have to master it).
• Use Java to relax from coding or deliberately slow down your application.
