values to the member objects declared in the base class ), then, call the value assignment operator of its member objects (change the Member objects declared in the derived class ). These assignments should usually appear in the same order as the base class and member object in the definition of this class. CDerived CDerived::operator=(const CDerived r){CBase::operator=(r);_c = r._c;return *this;} The correct format of the overload assignment operator is as follows: The C ++ designer

fascinating Graph Based on Google's search mechanism to reflect how well-known programmers are associated. Based on the seed resources on GitHub, Gómez found the names of the creators of the most popular programming languages, such as Brendan eich (JavaScript), James Gosling (Java), Rasmus lerdorf (PHP) dennis Ritchie (C), Bjarne stroustrup (C ++), and Brad Cox (objective-C ). If the search result contains a Knowledge Information graph, this programm

Return is a pre-defined C ++ statement that provides an amplification function for execution. When the return statement provides a value, this value becomes the return value of the function. when it comes to return, it is necessary to mention the definition of the main function. many even some books on the market use void main (), which is actually incorrect. Void main () has never been defined in C/C ++ (). The father of C ++ Bjarne stroustrup clearl

();//...// Call destructor XX here}Why is this program segment optimized? How to optimize it?Because the statementX xx = bar ();There are some improvements in the following two areas:1. The function of constructing bar_x is only to return its value, which is used to assign values to objects outside the function.2. Call the bar () function. A temporary object structure is returned, and a copy of the constructor is called.To illustrate this problem, see how the return value of Bar () is copied fr

, which forms the foundation of STL, and STL is now part of the standard C ++ library. Some quirks make history interesting. copy_if became one of the items abandoned in the cut room when filtering out some small and manageable items from hp stl for the standard. In the C ++ programming language [7], stroustrup emphasizes that copy_if writing is insignificant and he is right, but that doesn't mean that it is easy to implement the correct things. For e

efficient. Phase 3 Inside the C ++ Object Model (in-depth exploration of the C ++ Object Model)This book focuses on the underlying mechanism of C ++ object-oriented programming, including structured semantics, generation, encapsulation, inheritance of temporary objects, and virtual-virtual functions and virtual inheritance, it helps you understand the underlying implementation of the program to write more efficient code. The design and evolution of c ++ (Design and evolution of C ++) This book

successfully compiled by the compiler, but once it is run, we will getAn error occurred while running "exc_bad_access ".Because what we find through the address indicated by funcp is not the Function entry. It can be seen that although reinterpret_cast seems powerful, it does not play a very wide role. IBM's c ++ guide, the FAQ page of Bjarne stroustrup, the father of C ++, and the visual C ++ of msdn also pointed out:Incorrect use of reinterpret_c

stroustrup Biyani straustrup, born in ohusi-gun, Denmark, is a computer scientist and chief professor of computer science at the College of Engineering, Texas Agricultural and Engineering University. He is famous for creating C ++ programming languages and is known as the "father of C ++ ". In his own words, he "invented C ++, wrote down its early definition, and made its first implementation ...... C ++'s design standards have been selected, C ++'

(including one copy constructor, and others are called normal constructor ). If you do not want to write the above functions for any class A, the C ++ compiler will automatically generate four default functions for Class A, suchA (void); // default no-parameter ConstructorA (const A a); // default copy constructor~ A (void); // default destructorA operate = (const A a); // default value assignment functionThis is confusing. Why do programmers need to write functions automatically?The reason

Use the keyword abstract in C # To define abstract classes and abstract methods.Classes that cannot be initialized are called abstract classes. They only provide partial implementation, but the other class can inherit it and create them.."An abstract class that contains one or more pure virtual functions cannot be instantiated.An abstract class can only be used by interfaces and as the base classes of other classes.
