Requirements: The operation of the global variable obj. This is a very useful place for JS scripts. for example. we want to save the window position and size in the JS script. there are other things. it is a common requirement for game or

The where clause is used to specify type constraints. These constraints can be used as variables for type parameters defined in generic declarations. 1. Interface constraints: for example, you can declare a generic class.MygenericclassIn this way,

I can't compliment csdn's blog layout. It took me several hours to translate the first part of this blog and publish the result.CodePartially disordered. It took another quarter of a second to edit and retypeset online in the csdn editor! I really

Static_assert Assertion is an effective weapon to Improve the Quality of code. The assert macros and verify Macros in the C ++ standard library are examples of assertions. They all have the same thing in mind that they are used to judge the program

Standard streams use CIN and cout directly, and file streams and string streams use constructors.The default value is text stream. To use a binary stream to construct a stream, use the IOS: Binary flag. Output stream function: ostream member

What is the use of dynamic_cast? In fact, dynamic_cast is one of the only two usages in ansi c ++ related to rtti (Run time type identification. The class inheritance of C ++ makes it difficult to find out which class the object you are using,

The configuration is actually very simple. After adding lib and header files, it will be OK. Note that if you are using a dynamic library, you need to configure the DLL. The best way is to put the DLL under the compiling directory, In this way, the
