First, write as follows: Class A = B;Class A;A = B; It is not equivalent. The former is equivalent to a (B), and the latter is equivalent to a. Operator = (B) The problem is that I want to write a copy function similar to the following: Class(Class &

With the further study, we will gradually come into contact with the construction methods and design principles inside the computer. Among them, the addressing method of the computer is a very important concept. We need to understand it well. I.
