4)Write a C++ function named remove() that removes an existing structure from the linked list of structures creates. The argument passed to remove() function should be the address of the structure preceding the record to be removed. In the remove() function, make sure the value of the pointer in the removed structure replaces the value of the pointer member of the preceding structure before the structure is removed.

What Is A Const Pointer?

Which of the following statements is NOT correct? Group of answer choices C++ language provides a set of C++ class templates to implement common data structures, which is known as Standard Template Library (STL); In STL, a map is used to store a collection of entries that consists of keys and their values. Keys must be unique, and values need not be unique; In STL, a set is used to store a collection of elements and it does not allow duplicates; Both set and map class templates in STL are implemented with arrays.

Erlang File -module(exam). -compile(export_all). -include_lib("eunit/include/eunit.hrl").   Part A Implement a function called min which takes a tuple of two numeric values and returns the lower value of the two.Implementation notes:• If needed, use Erlang function guards• Do NOT use the if or case structuresSample calls:> exam:min({3, 4}).3> exam:min({4, 3}).3

need help in C++ Problem: You are asked to create a program for storing the catalog of movies at a DVD store using functions, files, and user-defined structures. The program should let the user read the movie through the file, add, remove, and output movies to the file. For this assignment, you must store the information about the movies in the catalog using a single vector. The vector's data type is a user-defined structure that you must define on functions.h following these rules: Identifier for the user-define structure: movie. Member variables of the structure "movie": name (string), year (int), and genre (string). Note: you must use the identifiers presented before when defining the user-defined structure. Your solution will NOT pass the unit test cases if you do not follow the instructions presented above. The main function is provided (you need to modify the code of the main function to call the user-defined functions described below). The following user-defined functions are…

What is a way to safely dereference a pointer?

1) Define a global variable Emps that is an array of pointers to employee structs. 2) Change your createEmployee function to add the new employee to the Emps array. It should place it in the first slot that contains a NULL. 3) Write a listEmployees function that will call your display function on each employee in the array. 4) Change main to have a loop that looks for user commands. • If the user types HIRE, you should call createEmployee. If the user types LIST, you should call listEmployees. • If the user types QUIT, you should exit the loop, which will then cause the program to exit. 5) Write a findEmployee function that takes a string parameter and returns the employee pointer with that name or NULL if no such person exists. Change main to add a FIND name command that will find and display a single employee.

To effectively utilize a shared virtual function across multiple forms and structures, what is the appropriate method for a program to invoke it when employing base class pointers or references?

Language: C Write the function convolve that will calculate the confolution of two functions f, g on [0, t] interval. The convolution is defined as (f ∗ g)(t) = Z t 0 f(τ )g(t − τ ) dτ for f, g : [0, ∞) → R. The argument function f and g should be passed by pointers. The integral should be approximated by the Riemman sum, i.e., Z b a f(x) dx = Xn i=1 f(xi) ∆x, where ∆x = b−a n and xi = a + i ∆x. Define the functions func1, func2 and func3, that return sin(x), cos(x) and x 3 respectively. Use these functions to calculate the convolution of ˆ f = sin(x), g = sin(x) ˆ f = sin(x), g = cos(x) ˆ f = sin(x), g = x 3 for t = 2π and n = 1000.

Game of Hunt in C++ language   Create the 'Game of Hunt'.  The computer ‘hides’ the treasure at a random location in a 10x10 matrix. The user guesses the location by entering a row and column values. The game ends when the user locates the treasure or the treasure value is less than or equal to zero. Guesses in the wrong location will provide clues such as a compass direction or number of squares horizontally or vertically to the treasure. Using the random number generator, display one of the following in the board where the player made their guess: U#  Treasure is up ‘#’ on the vertical axis (where # represents an integer number). D# Treasure is down ‘#’ on the vertical axis (where # represents an integer number) || Treasure is in this row, not up or down from the guess location. -> Treasure is to the right. <- Treasure is to the left. -- Treasure is in the same column, not left or right. +$ Adds $50 to treasure and no $50 turn loss. -$ Subtracts…
