A static member of a class is a love-hate trait. I decided to summarize the knowledge points of static class members so that I would not be passive on such issues in future interviews.Static class members include both static data members and static

Binary tree method evaluation is not the same as the Stack method, in addition to converting the operands in a string to floating-point types, a new node needs to be generated:1 voidCalculator::d Ealwithnumber (Char*&ptoken)Throw(string)2 {3 if(!
