Topical Information Use C++. This lab will help you practice with dynamic memory (NOT mixed with classes). Program Information One statistic of interest to many researchers is the median of a set of data. The median is the value in the middle. (This is NOT the average, mind you.) Being in the middle, of course implies that the data are in order (sorted). If there are an odd number of data items, the middle is simple to find. If there are an even number of data items, you are supposed to take the average of the two middle values. You'll need to find the median of a set of data from a file. You don't know how many data are in the file, of course. You'll have to count the data, then read them in to sort, then find the median, and finally print it (the median) out. Do NOT use any more memory than is necessary!!

Using C++ Without Using linked lists: Create a class AccessPoint with the following: x - a double representing the x coordinate y - a double representing the y coordinate range - an integer representing the coverage radius status - On or Off Add constructors. The default constructor should create an access point object at position (0.0, 0.0), coverage radius 0, and Off. Add accessor and mutator functions: getX, getY, getRange, getStatus, setX, setY, setRange and setStatus. Add a set function that sets the location coordinates and the range. Add the following member functions: move and coverageArea. Add a function overLap that checks if two access points overlap their coverage and returns true if they do. Add a function signalStrength that returns the wireless signal strength as a percentage. The signal strength decreases as one moves away from the access point location. Represent this with bars like, IIIII. Each bar can represent 20% Test your class by writing a main function that…

Q.1 Write C++ code that ask the user to enter any number greater than the minimum number, then the program will print a matrix (each student will have his/her own matrix. He/ she should figure out what is the relationship between the elements in that matrix). Enter any number to creat a matrix : 28 1 11 21 1 11 2 21 12 31 22 2 Enter any number to creat a matrix : 35 12 3 22 13 Process exited after 3.261 seconds with return value e Press any key to continue 32 23 3 13 4 23 14 33 24 4 14 24 5 34 15 25 5 15 25 35 Process exited after 3.595 seconds with return value e Press any key to continue

Problem 4) Suppose the following Course class is given: public class Course { private String name;//such as CS, MATH, etc private int grades[];//list of the grades //default and initial valued constructor //all other methods public double average() { double sum=0; for(int i=0;i=90) System.out.printf("me is a student with A letter-grade\n");
Problem Statement: The mathematician Conway imagined a game, called game of life, whichconsidered cells that are susceptible to reproduce, disappear, or survive when they obey certainrules. These cells are represented by elements on a grid of squares, where a grid has an arbitrarysize. Thus, each cell (except those on the boundaries of the grid) is surrounded by eight squaresthat contain other cells. The rules are stated as follows:1. Survival: Each cell that has two or three adjacent cells survives until the next generation.2. Death: Each cell that has at least four adjacent cells disappears (or dies) by overpopulation.Also, each cell that has at most one adjacent cell dies by isolation.3. Birth: Each empty square (i.e., dead cell) that is adjacent to exactly three cells gives birthto a new cell for the next generation.It is worth noting that all births and deaths occur at the same time during a generation.Write a program that simulates this game and displays all successive…
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…
