In the actual engineering application, after entering a special application, a function of the system does not work.Of course, there are so many ways that this communication can be done. I can think of at least some of the following1, the use of property familiar to achieve, such words need to add a special attribute;2, the use of the database. Add a record to the database and set it up when you enter the a
Special and partial features of templates
The reason why the template needs to be made special is that the compiler believes that if you can better implement a function for a specific type, you should listen to it.
Templates are classified into class templates and function templates. features are classified into full

In addition, we can only specialize in members rather than special classes. For example, in vector, we can only specialize in push_back operations:

two preprocessing functions:assert and ndebug. 14.Assert is a preprocessing macro, which is actually a preprocessing variable, a behavior type and an inline function:Assert (expr); when Expr to be 0 , assert Output Information termination program, Expr Non- 0 , assert don't do anything. 15. Preprocessing names have preprocessor non-compiler management.16. As with preprocessing variables, the macro name is unique within the program.the behavior of 17.Assert relies on the state of a preprocessing

First unlock is special, there is a definite behavior, 80% is to judge the role level, then the button is grayed out or hidden operation.Special effects and tips do not have a definite behavior.The main trade-off 2 points are the active call or the callback passive call, which means the code is messy. There is no unified portal, but it is also cumbersome to invoke the object parameter for active invocation.First I vetoed the practice of binding in the
with the CPU word length, if there are cross-platform requirements of software, it is best to use cross-platform-defined types.In C + + architecture, data tends to have memory alignment problems, and some compilers can set them up by compiler directives, which are best avoided by avoiding them.When you cross-platform, you should also be careful about exception handling code, because some versions of the C + + compiler do not conform to specifications for thrown exception specifications.In addit
