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.

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 ...
