    Important points about local class.
    • Local class is a class defined inside a function.
    • A local class type name can only be used in the enclosing function.
    • A Local class cannot contain static data members.

    public:

    void method() {
    cout << "Local Class method() is called";
    }
    };

    LocalClass obj;
    obj.method();
