Those two things in VC must have been used by anyone, but what is the difference between them? I just have time to study them. If there is a mistake, please make a brick.Based on vc2005, the 32-bit xp platform passed the test. It is estimated that other versions of VC and operating systems are not universal.1. Try... catchThis is defined in the C ++ language, and each c ++ has different implementations for it. it is easy to use. for example, we have a

Today's visit to the forum found a very interesting question: Who can give me an explanation of the result of this procedure is: 2.

Exception handling Java exception handling model in contrast to other languages, the keyword finally is the most outstanding new feature. The finally widget makes the code in the section always execute, regardless of whether an exception occurs, especially for maintaining the internal state of the object (used to ensure that the exception is in a valid state for recovering the object). To ensure that the program will automatically run again after processing the exception and to clean up non-memo

First try phantom 4 engine feelings, first try Phantom Feelings I downloaded the source code and compiled environment of unreal 4 in the last two days and tried it a little.
