- RECURRING?????????M .Using c++ Rolling for a pair Given two GVDie objects that represent 2 six-sided dice and an integer that represents a desired value as parameters, complete the function RollingForPair() in the main class. The main class rolls the dice until a pair with the desired value is rolled. The function RollingForPair() then returns the number of rolls thrown to achieve the result. Assume the desired value received from input is within the appropriate range, 1-6. Note: For testing purposes, the GVDie objects are created in the main() function using a pseudo-random number generator with a fixed seed value. The program uses a seed value of 15 during development, but when submitted, a different seed value will be used for each test case. Refer to the textbook section on random numbers to learn more about pseudo-random numbers. Ex: If the GVDie objects are created with a seed value of 15 and the input of the program is: 2 the output is: It took 82 rolls to get a pair of 2's. #include…
- Weighted Job Scheduling in C language Problem statement: You are given a list of jobs where each job has a start time, finish time, and the profit associated with that job, find the maximum profit subset of non-overlapping jobs. Problem description: The problem wants you to find the maximum profit that you can make after performing a certain number of jobs such that each job has a certain condition that you can start a job only if the start time of the current job is greater than the finish time of the previous job. You are required to develop some algorithm such that the job start time and the finish time does not coincide with other jobs.A c++ program in which your team is creating a game ludo. You are working on player class. It contains thefollowing information.o Current position of player (between 1 to 100)o Player alive pawns (Gooti)o Does the player have its turn now or not.Player data can be initialized via constructor and via one setter function. Player data (attributes) can be fetched using getter() function but with the conformation that via getting data player data cant be changed or updated. (user constant functions)Using c++ In main.cpp, complete the function RollSpecificNumber() that takes in three parameters: a GVDie object, an integer representing a desired face number of a die, and an integer representing the goal amount of times to roll the desired face number. The function RollSpecificNumber() then rolls the die until the desired face number is rolled the goal amount of times and returns the number of rolls required. Note: For testing purposes, the GVDie objects are created in the main() function using a pseudo-random number generator with a fixed seed value. The program used during development uses a seed value of 15, but when submitted, different seed values will be used for each test case. Refer to the textbook section on random numbers to learn more about pseudo-random numbers. Ex: If the GVDie objects are created with a seed value of 15 and the input of the program is: 3 20 the output is: It took 140 rolls to get a "3" 20 times. #include <iostream>#include "GVDie.h"using…
- Please written by computer source java codeplease write with proper explanation. Question half solution is here please write what is main disadvantages of this approach? Half solve questions: Mutual Exclusion: Mutex is an abbreviation for Mutual Exclusion. It is a programme object that prevents multiple users from accessing a shared resource at the same time. When a process accesses a shared variable, it is said to be in the critical section. When no two processes are present in the critical section at the same time, this is referred to as Mutual Exclusion or Mutex. while (true) { semaphore sem = S; while (S <= 0) do no operation { S = S-1; wait (S); } /*critical section*/ while (S > 0) { S = S+1; signal (S); } /*remainder section*/ }subject: programmimng language: c++ Question: Create a class Time with private data members hour, minute, second. The class must alsohave public functions setMinute(), setHour and setSecond() to set values of hour, minuteand second, and printTime() to print time in format: hh:mm:ss
- An Automatic Teller machine (ATM) is an Electronic Device that provides services like balance inquiry, cash withdraw and money transfer etc. The ATM system is considered an example of a safety critical system and hence the need to formalize its services. To formalize the ATM system we need to first declare variables to be used.- An ATM card contains the following information CARD := cardNo | accountNo | expiryDate - After any transaction the ATM machine gives the following responses ATMRESPONSE := operationSuccessfull | operationFailed - An ATM can be in two states STATE := available | busy - For any withdraw operation the ATM machine has restrictions on the minimum and maximum amount one can withdraw. AMOUNT := minimumAmount | maximumAmount - The other important variable is the date DATE := issueDate | expiryDate | todayDate - The ATM generates the following possible error messages ERROR := invalidCard | invalidPin | invalidAmount | insufficientBalance - Below is a schema for a Bank…C++ Write a program that simulates the minute-by-minute operation of a checkout line, such as one you might find in a retail store. Use the following parameters: Customers arrive at the checkout line and stand in line until the cashier is free. When they reach the front of the line, they occupy the cashier for some period of time (referred to as ServiceTime) measured in minutes. After the cashier is free, the next customer is served immediately. Customers arrive at the checkout line at ArrivalRate per minute. Use the function included below (customerArrived()) to return the number of customers arriving in a given minute, determined randomly. The line can only hold so many people, MaxLineSize, until new arriving customers get frustrated and leave the store without purchasing anything. The overall time of the simulation is SimulationTime, measured in minutes. The program should take 5 inputs (to be read from a text file named simtest.txt, one per line): SimulationName - a string…using c++ In this assignment you are going to implement your own version of university library system,Thesystem will have two different sides , the first one is to help the librarian to do his job and the other side for admin to manage every one permissions in the system , so You should provide the following features in your system: Admin view o Add/remove Studentso Add/remove librarian o Add/remove other admins Librarian viewo Add/Delete bookso Issue/Return bookso View bookso View Issued bookso Log in /log outo Search for the book(id/name) Simple backend for your system , You could use a file each row should represent itemo Books File should be something like:Id , Book Name, Author Name, Available quantity, Issued Quantity1,Oliver Twist, Charles Dickens,98,2In the previous the first row was the name of each column , you can do that or handle it in your code , id =1 , Book Name =Oliver Twist ..Etc.
