Negative tive C ++ Reading Notes (45-50): Miscellaneous Discussion

Item45 -- clearly knows which functions the C ++ compiler silently completes and calls for us

Constructor, copy constructor, destructor, assignment, and address Retrieval

Item46 -- I would rather encounter errors during compilation and connection than execution.

Abstract A month into a class. The class mechanism allows you to discover errors during compilation and connection. This is a little too advanced and generally not used. Ignore.

Item47 -- before using non-local static objects, determine whether it has an initial value.

You can use the single-key mode to resolve this issue. When the function is used to declare a static variable, it is initialized when it is used for the first time and then obtained directly.
Item48 -- do not view the warning information of the compiler as missing
C ++ is really a difficult language, so we can only remember one of the following cases.

Class B { Public: Virtual void F () const; }; Class D: Public B { Public: Virtual void F (); }; Warning: D: F () hides virtual B: F ()

This compilation error indicates that F () in B is masked, and const B * pb cannot be used to call the F () function.

Item49 -- try to familiarize yourself with the c ++ Standard Program Library

No, STL should be familiar. This is a long way to go. Now, we mainly refer to the reference of www.cplusplus.com.
If you have time, you will also want to read some books such as objective STL and STL source code analysis.

Item50-enhance your understanding of C ++

I want to read two books, the design and evolution of C ++, the annotated C ++ Reference Manual
Now let's take a look at the basics and time.

 

Postscript:

Objective C ++ has been read for a long time, but now it is worth looking back and reading many things again. I think it is a necessary book to study c ++ in depth, scott Mayers is very familiar with many details. He can tell all his thoughts in this book in his own words, which is easy to understand, therefore, C ++ is proficient, and now it is only a rough record of what you think, so this goal is worth years of effort.
