foo1為指向Foo型別object的pointer,但此時僅有pointer還沒有object,所以等同C#的Foo foo1。 foo2真的是一個object了,相當於C#的Foo foo2 = new Foo(); foo3是一個pointer指向Foo object,此時是一個建立在stack的object,不需手動delete刪除。 foo4是一個pointer指向Foo object,此時是一個建立在heap的object,需...

function pointer是C語言中最高級的機制,大概很多人還沒上到這裡已經學期末了,所以不少C語言工程師根本不知道C語言有function pointer;而C#的delegate大抵跟C語言的function pointer功能相同,所以很多書說delegate是物件導向的function pointer;C++的function object功能則比function pointer略強,還可配合泛型使用。

因为子文件中引用主程序定义的结构体出错。解决:将子程序文件中 子函数移至主文件。结构体也是一种数据类型，只不过在这种数据类型中又包含了几个基本的数据类型。构体变量在内存中的存放和基本数据类型变量在内存中的存放是不同的，基本数据类型的存放系统是会给分配一块连续的空间用来存放，而结构体...
This change may expose pointer truncation bugs in existing code. By default, this switch is on. To disable this behavior, specify /HIGHENTROPYVA:NO. The managed compiler (Visual Basic/C#) also supports /HIGHENTROPYVA for managed builds. However, in this case, the /HIGHENTROPYVAswitch is ...

Another possibility is probably make it possible to load plugins from a c-shared library, which may be less work. Then you can build one c-shared object to just do the plugin loading, and building other extensions as plugins. This is interesting but does not seem attractive, at least for...
