What is a class instance?

Object of the defined class

For example, you have defined the following class:
Class
{
Public:
// Member functions
Private:
// Member variable
};
A a; // indicates that you have defined an instance of Class A. In fact, it is similar to defining A common type variable,

However, the type here is changed to Class A, instead of basic types such as integer, which can be like: int I;

I is equivalent to an instance of the int type.

This is the same as struct.

Struct Student (){

Char name;

Int number;

}

Int mian (){

Student * Tom = new Student;

}
