Function Overloading is used to describe functions of the same name that have the same or similar functions, but the data type or function management operations with different parameters!Let's take an example in practical application to illustrate

In a well-designed object-oriented system, in order to compress the space inside the object, only two functions are left for copying objects: copy constructor) and copy assignment operator ). They are collectively referred to as copying functions ).

Suppose we want to write an application that can send messages to several different companies. Messages can be transmitted in either encrypted or plaintext (not encrypted) mode. If we have enough information to determine which message will be sent
