Today, I will talk to you about how to store properties and methods in C++, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following. I hope you can get something from this article.

Content introduction:

For a Class in C++, how on earth are its internal data and methods stored? Do you store both data and methods in a single object in Class, or do you store data and methods separately? As shown in the following figure:

The answer is figure 2, each object takes up storage space only in the data part of the object (virtual function pointers and virtual base class pointers also belong to the data part), and the function code belongs to the common part, so in Class storage, the data part is associated with the object, and the function part is stored in a common place.

Code example:

# include using namespace std

Class Node {public: int age; string name; void print ();}; void Node::print () {cout
