- Why is it vital to implement a destructor in a class?MemoryManagerFirstFit The MemoryManagerFirstFit class is derived from the MemoryManagerBase class. Based on the TODO entries in memory_manager_first_fit.h and memory_manager_first_fit.cpp, implement the functions as instructed. memory_manager_first_fit.cpp #include "memory_manager_first_fit.h" #include using namespace std; MemoryManagerFirstFit::MemoryManagerFirstFit(int size) { // Set up the list of memory blocks with the info for this initial // unallocated block. memory_block b; // TODO: Fill in the appropriate values here based on the data elements // you added in the header file. // Add the block to the list of blocks m_blocks.push_back(b); } // Allocate a block of memory of the given size // We will walk through our current list of blocks and // find the block with the first fit. int MemoryManagerFirstFit::allocate(int size, string name) { // TODO: Implement the allocate logic here // // Iterate through the current list of blocks // and find the first one that is big enough…C++ requires that a copy constructor's parameter be a class object passed by _________________.
- Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works. Next add the following public methods to the Address class and test them from main as you go: Write getters and…How should a software utilize pointers or references from the base class to invoke the same virtual function so that it may be used in different data types?There is a class Team, that holds information about the team name, number of players in the team, and player’s code. Design the constructor function that decides the number of player in the team and initializes code for each player. Create a team and display its all data. In C++(Implement dynamic memory allocation).
- Write the program of object orientation programming c++. Write a program with a class that contains an array of integers. Initialize the integer array in the constructor of the class. Then create two friend functions to the class to find the largest and smallest integers in the array. (One function should be global)Create a destructor that sets all of the elements in the array to 0.A counter variable is normally used in a program to keep track of the current count value.Create your own counter data type which is able to perform common counter operations such as increment (by one) the counter value and decrement (by one) the counter value. It is also able to set the counter to a specific value and to retrieve the counter value. The minimum value the counter can attain is zero, while the maximum value attained is stored in attribute maxValue. The class should have the following private members (attributes): (first picture) In the main program, test the workablity of your member functions by first setting an initial value to the counter. Display this value before proceeding. Then test other functions by randomly incrementing and decrementing the object’s value. Be sure to keep track of your actions. At the same time you should also make sure that your minimum value should not be less than zero. Once this is reached you will not be allowed to do further decrements.…Design a class named Array with the data members capacity, size, and arr (a pointer that points to the first element of the array in the heap). Also design a member function named insert that adds elements to the end of the array, and a function named print that prints the element of the array. Test your program with two arrays: Array 1 that returns three elements and Array 2 that returns 20 elements with an increment of 10 between each element. Include a header file, an implementation file for the Array class, and the application file to test the Array class.
- LocalResource(String date, String sector)- Actions of the constructor include accepting a date in the format “dd/mm/yyyy”, initializing the base class, storing the sector and storing an id as a consecutively increasing integer. Note that the constructor must ensure that the date of birth information is recorded. b. getId():Integer - returns the ID of the current instance of LocalResource c. getSector():String – returns the sector associated with the current instance of localResource d. getTRN():String – returns the trn number of the current instance of LocalResource. The process used to determine the TRN is to add the id to the number 100000000 and then returning the string equivalent. e. Update the NineToFiver class to ensure it properly extends the LocalResource class f. In method getContact() of NineToFiver, remove the comments so that the method returns "Local Employee #"+and the id of the contact. Write a concrete class LocalConsultant that extends LocalResource, and implements…Define a class counterType to implement a counter. Your class must have a private data member counter of type int. Define a constructor that accepts a parameter of type int and initializes the counter data member. Add functions to: Set counter to the integer value specified by the user. Initialize counter to 0. Return the value of counter with a function named getCounter. Increment and decrement counter by one. Print the value of counter using the print function. Example output: Counter = 0. The value of counter must be nonnegative.using C++ 1- Creates a class called Member with two integer x and y.a. Add a constructor able to create a Member object with tow integers and the default values 0,0.b. Add the methods setX and setY to modify the attributes x and y; [2 Markc. Add the method display able to display the attributes. 2- A Stack is a special array where the insertion and deletion will be via a specific index called "head". A Stack is characterized by 3 attributes:a. capacity (int): the maximum number element Member that can be contained into the Stack.b. head: presents the index where we can add/remove element to the Stack. The head value presents also the current number of elements into the Stack. When a Stack is created the initial value of head is 0.c. Member content[]: an array of elements of type Member. Creates the class Stack with the following methods:a. bool empty(): this method returns true if no element exists in the Stack. b. bool full(): this method returns true if there are no place to add a…
