1. What is Operator overload? Operator overloading can be divided into two parts: "operator" and "overload ". It should be no stranger to heavy load. This isPolymorphism during compilation. overloading can be divided into function overloading and

There are two methods of C ++'s static: process-orientedProgramStatic in design and static in object-oriented programming. The former applies to common variables and functions, and does not involve classes. The latter mainly describes the role of

1. virtual functions in C ++ C ++The role of virtual functions in is to implement the polymorphism mechanism. With regard to polymorphism, in short, the pointer of the parent type points to the instance of its subclass, and then calls the member

I don't know what other schools are doing, but I learned C language in my freshman year and C ++ in my freshman year. At that time, I just entered the Software Institute. Where can I find out what C/C ++ is, let alone what is the relationship

Under normal circumstances, most people may only consider simple representations such as \ r \ n \ t, However, when using COM components such as Excel, you must use a CHR (INT) similar to VB. NET to convert it to the ASCII character set. C #

I. abstract class: Abstract classes are special classes, but they cannot be instantiated. In addition, they have other characteristics of the class. It is important that abstract classes can include abstract methods, which are not supported by
