Explain what is local class

Local class in C++ :

A class defined inside a function is a local class.


Example of local class in C++:

void printData()
{
  static int count=0;
  count++;

 class Data
 {
   public:
   int age;
   int unique_id;
   void display()
    { cout<< count << " " << unique_id << " " <<age; }
    
 };
 Data jay;
 jay.age=25;
 jay.unique_id=1;
 jay.display();
}

int  main()
{
  printData();
}

 

Scope of local class is within the enclosing function where it is defined.

It has same access permission to the identifier outside the enclosing function as the enclosing function.
The enclosing function does not have special access to members of the local class. Also all the member function's definition needs to be defined within class definition.

A local class cannot have static data members.
