classes written in one language should be able to communicate directly with classes written in another language, especially:
Classes written in one language should inherit classes written in another language.
A class should be able to contain instances of another class, regardless of the language in which they are written.
An object should be able to directly call the method of another object written in other languages.
Objects should be passed between methods.

Now, you should know that all the content of CLR is centered on the type, and the type provides the required functions for your application and other types. type also serves as a mechanism for seamless integration of code written in one language with code written in another language. because types are the foundation of CLR, Microsoft has created a formal document description-General Type System (CTS)-to express how types are defined and what their beh

game development libraries, such as ogre and klayge, and third-party thread libraries, such as C ++ threads and zthreads, there are many others; third, high performance of C ++. This feature of C ++ is also unquestionable. Most of the operating systems, embedded development, games, and image software we know are inseparable from C ++, this is closely related to the high performance of C ++. From this point of view, this is what many other modern advanced languages lack, that is why C ++ still h

In addition, the attack device used does not need high transmit power, it is difficult to find and locate the attacker.

. Android Market is the only Android app store with more than 40 thousand programs and contracts with each Mobile Phone OEM. This restriction is terrible because no OEM is willing to release Android phones without a market (tianchao is an alternative ). Of course, releasing an application on the market is very simple and there is no approval process. This is just the opposite of Apple's appstore.
