Create a class for smart pointers. A smart pointer is a data type that simulates a pointer and offers automated garbage collection. It is often implemented using templates. When the number of references to a SmartPointerT*> object drops to zero, the object of type T is immediately released.

- Differences between void and NULL pointers are as follows: Provide relevant instances to back up your claim.Smart Pointer: Write a smart pointer class. A smart pointer is a data type, usually implemented with templates, that simulates a pointer while also providing automatic garbage collection. It automatically counts the number of references to a SmartPointer<?> object and frees the object of type T when the reference count hits zero.1] When does the void pointer can be dereferenced? A.when it doesn't point to any value B.when it cast to another type of object C. using delete keyword D. none of the mentioned
- Here's the difference between a void pointer and a NULL pointer: Provide relevant instances to back up your claim.write a program to overload the delete operator so that it works with objects of class which contains a pointer to a character.Write a program that will sort a prmiitive array of data using the following guidelines - DO NOT USE VECTORS, COLLECTIONS, SETS or any other data structures from your programming language. The codes for both the money and currency should stay the same, the main focus should be on the main file code (Programming language Java) Create a helper function called 'RecurInsSort' such that: It is a standalone function not part of any class from the prior lab or any new class you feel like creating here, Takes in the same type of parameters as any standard Insertion Sort with recursion behavior, i.e. void RecurInsSort(Currency arr[], int size) Prints out how the array looks every time a recursive step returns back to its caller The objects in the array should be Money objects added or manipulated using Currency references/pointers. It is OK to print out the array partially when returning from a particular step as long as the process of sorting is clearly demonstrated in the output. In…
- Implement a function writeEmpToFile that takes two arguments: a struct Employee pointer and a FILE *. It should write each field in order as an appropriate type. Note that you will probably want to write a length of the name before you write the characters of the name. By doing this, when you write the load function below, you can read the length of the string and use it to malloc a buffer of the proper size to hold the name. Because of the embedded name pointer, you CAN NOT write the Employee struct as a single struct. You will need to write it out field by field. You will want to write this as a binary file, not as a text file. Implement a SAVE command in your main loop that will save all the employees out to a file. The SAVE command should ask for a file name, similar to the way your FIND command asked for a name. Below is the work I have done so far that is required from the image but I have not been able to finish it and I need assistance with making the final changes that…I have written a class that has the characteristics of the data structure Set and within it house an array that stores 10 integers. I would like a function written in C++ that will perform a set union comparison between two class set instances and only print out one of each element from both of them, (no duplicates). Thanks!Write a Template function body called swap( ) to swap the values of the two values of integer, doubles and character respectively using pointers for swapping. (Write only template function body)
- This question was already answered which was incorrect.Please use pointers In c++ Make the print function in the petRecord class virtual. Create a new main that creates a PetRecord pointer, then asks the user if they want a cat, dog or bird, and creates the appropriate pet type at the pointer (use the keyword new and the default constructor). Print its’ information using the print function, including the information specific to that pet type (works due to polymorphism). Finally, delete the object at the pointer. NOTE: Answer only if you know this answer otherwise I wil downvote also don't copy from other platforms ThankyouWhen should a pointer parameter p be a reference parameter? Group of answer choices When the function changes p, and you do NOT want the change to affect the actual pointer argument. When the function changes p, and you want the change to affect the actual pointer argument. When the pointer points to a large object. When the function changes *p, and you do NOT want the change to affect the the object that is pointed at. When the function changes *p, and you want the change to affect the the object that is pointed at.Write a program to implement binary search algorithm on a dynamic array of objects of “patient” class.“patient” class contains attributes (privately defined) patient_id (int), pat_name (string) andpat_app_date (string). “patient” class should also contain member functions (publicly defined):constructor, input and output function. User will provide values for attributes for objects of “patient”class as input. Objects are required to be stored in array in ascending order on basis of patient_id. Binarysearch function should check for an object of “patient” class which will be input by user as a key valueon basis of patient_id attribute. If object is found its index location in array should display, otherwiseprogram should display a message that value is not found.
