True FalsePut the class definition in House.h and the implementation of the constructors and functions in House.cpp 1. Define a class called "House", that represents the information of a house. A House is defined with these attributes: age (int), type (string) (for example Detached, Semi-Attached, Attached) and build_cost (double). Functions of the House class must perform the following operations: ✓ A default constructor which sets all the numeric instance variables to zero and the String instance variables to empty String. ✓ A constructor with 3 parameters which sets the 3 instance variables to the corresponding values passed. ✓ Implement a getter function for each of the 3 instance variables that will return the value of the instance variable. For example, the getX() function for the instance variable type must be called getType(). ✔ Implement a setter function for each instance variable that will assign to the instance variable to the value passed. For example, the setX() function for the…
- CPU Scheduling Algorithm Simulator in C++Instructions:Create a .zip file consisting of code, output files, readme file .The readme file should explain briefly your code. The simulator will consists of following classes:(i) Process: The data members of this class should store process id, arrival time in the ready queue,CPU burst time, completion time, turn around time, waiting time, and response time. The memberfunctions of this class should assign values to the data members and print them. A constructorshould also be used.(ii) Process_Creator: This class will create an array of processes and assign a random arrival timeand burst time to each process. Data members, constructor and member functions can be writtenaccordingly.(iii) Scheduler: This class will implement the scheduling algorithm. The class will maintain a readyqueue of infinite capacity (i.e., any number of processes can be accommodated in the queue). Theready queue should be implemented using the min-Heap data structure…solve in c++ Create an application for a supermarket owner. The owner would like to storeup to 50 items. Each item is represented by an ID and a price.The program should ask the user if he/she wants to do one of the followingtasks:1. Enter an item ID and price2. Retrieve the price of a specific item3. Display all items within a specific range of prices4. Delete an item5. Display all items6. Delete all itemsNote: The items should be stored in memory sorted based on price. The six tasks should be implemented as functions.The program should run continuously until the user presses 'e' to exitBank ProgramThis c++ assignment uses the same account class created in Lab #4 with a more generally useful interface. It reads commands from a bank.txt file. Your program must process the following four commands.Create account amountDeposit account amountWithdraw account amountBalance accountIn all of the above commands, account is an integer and amount is a double.The following program behavior is required –1. Valid account numbers are 1-9. This requires the program to have an array of references to Account objects.2. If the first word on any line contains a command other than the four listed above, an error message should be displayed and that line ignored.3. The create command creates a new account object with the given account number and initial balance. If an account already exists with that number an error message should be displayed and the command ignored.4. The Deposit and Withdraw commands perform the indicated operation on an existing account. If no account with that number…
- A "generic" data structure cannot use a primitive type as its generic type. O True FalseApex Salestorce Write a Batch Apex Class to update the Account Name using good demonstrated Example Details Account Name Name update Account Name - Name**** Please write the program in the salesforce Apex Program and Also Show The execution of batch and Output with properC++ Programming Requirments: Please submit just one file for the classes and main to test the classes. Just create the classes before main and submit only one cpp file. Do not create separate header files. Please note: the deleteNode needs to initialize the *nodePtr and the *previousNode. The code to do this can be copied from here:ListNode *nodePtr, *previousNode = nullptr; Part 1: Your own Linked ListDesign your own linked list class to hold a series of integers. The class should have member functions for appending, inserting, and deleting nodes. Don't forget to add a destructor that destroys the list. Demonstrate the class with a driver program.Part 2: List PrintModify the linked list class you created in part 1 to add a print member function. The function should display all the values in the linked list. Test the class by starting with an empty list, adding some elements, and then printing the resulting list out.
