There is an assignment-compatible relationship between the base class and the derived class object, because the derived class contains members that inherit from the base class, in the following respects, the required friend can refer to the only

The return type of C + + functions, including when does const work? The function return value does not want it to be modified immediately. As an example, this is a simple way to avoid the creation of the invisible return variable, the

[TOC]When a templated class is used as a base class, there are areas to be aware of. As an example, suppose you now write a program that sends information to a different company, the information is either translated into a password, or it is the

First, what is memory alignment and why is memory alignment required?The memory space in modern computers is divided by Byte, in theory it seems that access to any type of variable can start from any address, but the reality is that when accessing a
