The priority queue in C + + is a derived container in STL, which only considers the highest priority elements. The queue follows the FIFO policy, and the priority queue pops up the elements according to the priority, that is, the element with the highest priority pops up first. It is similar to a normal queue in some ways, but different in the ...

C++ static_cast,dynamic_cast,const_cast and reinterpret_cast (four types of conversion operators) Implicit type conversion is safe and explicit type conversion is risky. The reason why C language adds the syntax of forced type conversion is to emphasize the risk and make programmers aware of what they are doing. However, this way of emphasizi ...

C + + conversion constructor: converts other types to the type of the current class In C/C + +, different data types can be converted to each other. It is called automatic type conversion (implicit type conversion) if the user does not need to indicate how to convert, and it is called forced type conversion if the user needs to explicitly indi ...

1, Process oriented and object oriented Before learning classes, let's review some connections and differences between C language and C + +: C language is process oriented, focusing on the process, analyzing the steps of solving the problem, and gradually solving the problem through function call. At the code level, it embodies functions. ...

1, Why addressing We know that data is stored in memory. The CPU needs to use the data stored in memory. To use a data, we need to find the data in memory. What to find is to use the memory number, that is, the address, to find the location of the data in memory, take it out for use, or put it back to the specified locationThe above is an addr ...

Under the mountain front bridge, there is a fool. A pupil, living in seclusion in a barren mountain. I have a group of dogs and a cat. Like programming, lack of money to do odd jobs. Mathematical history, French in mind. He can cook and wave. Statement: I'm not a professional Qt developer. The project needs a localized system scenario. Therefo ...

This chapter mainly studies the basic knowledge of template formal parameters. There are three types of template parameters: type template parameters, template parameters of templates (taking templates as template parameters), and non type template parameters. Type template parameters Type template parameters are the main purpose of using te ...

Today, let's talk about monotonic queues and stacks. Although these two data structures are not directly implemented in c + + stl, it is easy to use monotonic queue (stack) in the process of doing questions, especially in some difficult questions. Monotone queue 1.1 introduction to monotone queue Monotonic queue is the monotonous relati ...

Gobang based on human experience (2) Based on the previously established rules, a primary Gobang computer is established. We use the rules to score each position on the chessboard, and then find the position with the highest score to choose; Despite a good start, this still cannot simulate a "visual" data for it. Before proceeding t ...
