prevent copy c++

To prevent copying in C++, you can use the private access specifier for the copy constructor and the assignment operator of a class. This prevents the automatic generation of these methods by the compiler. By not providing implementations for these methods, you effectively disable copying of objects of the class, making it non-copyable. Additionally, you can declare these methods as private and provide no implementation to prevent their use outside of the class. Finally, you can also use the C++11 "delete" keyword to explicitly delete the copy constructor and assignment operator, making them inaccessible and preventing copying.
