Write a function with the interface doRandomWalk(nstep,startPosition), that takes the number of steps nstep for a random walk and the startPosition of the random walk on a straight line, and returns the location of the final step of the random walker. Problem Part B Now, write another function with the interface simulateRandomWalk(nsim,nstep,startPosition) that simulates nsim number of random-walks, each of which contains nstep steps and starts at startPosition. Then, this function calls doRandomWalk() repeatedly for nsim times and finally returns a vector of size nsimcontaining final locations of all of the nsim simulated random-walks. Problem Part C Now write a script that plots the output of simulateRandomWalk() for nsimnstepstartPosition===1000010−10 The resulting plot should look like the following, How do you interpret this result? How can uniformly-distributed random final steps end up having a Gaussian bell-shape distribution.
Design and code a class in C++ that represents a single month of the year. It should have a single integer-typed data member to represent the month. Make sure to provide proper construction, access, and mutation for this member as well as input and output methods. In addition, methods for comparing two months chronologically for ordering would be useful as would a method to advance to the next month (note that January follows December and begins the cycle anew) or previous month. In fact, thinking about it, it might be good to be able to advance to a month an arbitrary number of whole months in the future or past: January '+' 5 = June; March '-' 5 = October. Place your Month class in a library. Write a test application (driver) for your class. Oh, and the programmers who commissioned this class wanted to make sure it could handle not only integer-valued representation of a Month but also either whole-word names or three-letter abbreviations for the Months. That means that they should…
In C++ Given main() and the Instrument class, define a derived class, StringInstrument, for string instruments. Ex. If the input is: DrumsZildjian20152500GuitarGibson20021200619 the output is: Instrument Information: Name: Drums Manufacturer: Zildjian Year built: 2015 Cost: 2500Instrument Information: Name: Guitar Manufacturer: Gibson Year built: 2002 Cost: 1200 Number of strings: 6 Number of frets: 19 #include "StringInstrument.h" int main() { Instrument myInstrument; StringInstrument myStringInstrument; string instrumentName, manufacturerName, stringInstrumentName, stringManufacturer, yearBuilt, cost, stringYearBuilt, stringCost, numStrings, numFrets; getline(cin, instrumentName); getline(cin, manufacturerName); getline(cin, yearBuilt); getline(cin, cost); getline(cin, stringInstrumentName); getline(cin, stringManufacturer); getline(cin, stringYearBuilt); getline(cin,…
PROBLEM: Based on the given class diagram, create a class implementation using C++. Voters - active_Account: string - name: string - age: integer - precint_Number: string + setAccount(String account): void + getAccount(): String + setName(String fullname): void + getNamet(): String + setAge(Integer presentAge): void + getAge():Integer + setPrecintNo(String account): void + getPrecintNo ():String NOTE: Using the constructor, create three objects from class Voters and store it in the stack memory. Two voters must have an active account and one voter has a deactivated account. ● Please note that the deactivated voter account must be still part of the "object". Test all the functions by making calls. SAMPLE RUN: You have an Active Voters account! Your full name is Juan Dela Cruz. You are 25 years old. You Precint Number is 125-A. You have an Active Voters account! Your full name is Peter Simon Perez. You are 65 years old. You Precint Number is 347-B. You have an Deactivated Voters account!…
Please help me design a Airworthy class in C++. Develop a high-quality, object-oriented C++ program that performs a simulation using a heap implementation of a priority queue. A simulation creates a model of a real-world situation, allowing us to introduce a variety of conditions and observe their effects. For instance, a flight simulator challenges a pilot to respond to varying conditions and measures how well the pilot responds. Simulation is frequently used to measure current business practices, such as the number of checkout lines in a grocery store or the number of tellers in a bank, so that management can determine the fewest number of employees required to meet customer needs. Airlines have been experimenting with different boarding procedures to shorten the entire boarding time, keep the flights on-time, reduce aisle congestion, and make the experience more pleasant for passengers and crew. A late-departing flight can cause a domino effect: the departure gate is tied up and…
Write a simple C++ program that: Implements a class with three data members {sum (int), count (int), avg (float)}. Implement the following 3 member functions: The first function is a default constructor which initializes sum and count to zero. The second function is named add which receives an integer number as input parameter and add it to sum and increment count by 1. The third function is named output which divides the sum over count and save it to avg then print the avg value). Then, write a program to read numbers from the user until entering zero. The program uses the previous class to calculate and print average of {positive, negative} numbers.
Implement the classes according to the given class diagram. It shows both the composition and aggregation relationships. Driver has a Vehicle and Engine is a part of that Vehicle. [Note: consider the necessary data members, constructors, destructors and member functions accordingly] Note: solve as soon as possible use C++ LANGUAGE Class diagram is given
Design a class named LinearEquation for a 2-by-2 system of linear equations:ax + by = e x=(ed-bf)/(ad-bc)cx + dy = f y=(af-ec)/(ad-bc)The class contains:• Private double data fields a, b, c, d, e, and f.• A constructor with the arguments for a, b, c, d, e, and f.• Six getter methods for a, b, c, d, e, and f.• Methods getX() and getY() that return the solution for the equation.• A method named isSolvable() that returns true if ad - bc is not 0. The method isSolvable() willbe called in the main, if it returns true display the calculated values for x and y by calling getX()and getY(). If the call to isSolvable() returns false, display a message that “the equation has nosolution”.Write a test Java program that prompts the user to enter a, b, c, d, e, and f and displays the result. After the valuesfor a through f are entered, create a LinearEquation object. Check to seeIf ad - bc is 0, report that “The equation has no solution”, otherwise print out the values for x and y.
Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format.

Develop with Java programming language a calculator (console application) that takes a number, a basic math operator ( + , - , * , / , % ), and a second number all from user input, and have it print the result of the mathematical operation. The mathematical operations should be wrapped inside of functions. Note: Do please use the provided source code template to implement your solution. The purpose of this problem is not only to assess the students' ability to build a valid implementation but also to assess the ability to read the Java code. Input: On single line a number, a basic math operator ( + , - , * , / , % ), and a second number all from user input. Output: On new line result of the mathematical operation. In the case of "Division by zero" you must printout the text message "Error". The code must have the structure as shown in the picture and should work for negative numbers as well
