a const variable and that the variable must be initialized. You might say that this const is not the same? constexpr is more rigorous, the expression used to initialize the variable must be a ' constant expression ' . This means that the constexpr variable is a const variable initialized by a constant expression . As for the constant expression, we'll talk about it later, for the basic data type, the constant expression is a literal constant, a variable that constexpr the limit, and a cons

Here are the notes I made after reading the 6th edition of C + + Primer Plus, as a memo to facilitate review later.Notes section Why is C + + const better than C # # #? First, it can explicitly specify a type and have type checking capabilities.Second, you can restrict a definition to a specific function or file by using a scope rule for C + +.Third, you can use the const for more complex types, such as arrays and structs. The C l

The details and understanding of each knowledge recorded in this review are recorded so as to facilitate subsequent warming.First: Quick Start1.

C + + primer is almost finished, but it is absolutely impossible to read this book in light. Read at least two times and do most of the operational exercises again to remember most of the details. Here, I would like to make a very very, very brief but integrated core part of C + + 's first--c++ Foundation, and take a glance at C + + (a very shallow part) instead of getting lost in detail.Chapter II variables and basic types2.1 Basic built-in types1.c+

Note: This series of reading notes is Bo Master writing in two or three years ago, so is based on the "C + + Primer" Fourth edition, the book has been updated to the fifth edition, the fifth version is based on the C++11 standard, seemingly updated quite a lot. Bo Master graduate this year, if the array can be desired to find a copy of the work of the Linux/C + +, I will reread the fifth edition, and the series of reading notes to update. In addition,

Tim Shen 2017-08-21318 Inline Functions C + +(c + + Primer, 5th edition, page 215) and the book says, "for a given inline function or constexpr function, its multiple definitions must be exactly the same." For this reason, inline functions and constexpr functions are usually defined in the header file. Why don't you put it in the source file? I used the online example (the inline keyword inline in C + +) to run: A.h #pragma once Class A {public

nested namespace Querylib is Cplusplus_primer::querylib::query Unnamed namespacesUnnamed namespaces are not given a name when defined.Unnamed namespaces differ from other namespaces in that the definition of an unnamed namespace is local to a specific file and never spans multiple text files.

sequence block enclosed in curly braces. The try block is followed by one or more catch clauses. Each catch clause consists of three parts: a keyword catch, a single type in parentheses, or a declaration of a single object-called an exception specifier, and a block of statements that is usually enclosed in curly braces. If a catch clause is selected to handle the exception, the associated block statement is executed. Once the catch clause finishes executing, the program process proceeds immedia
