- Write a smart pointer class. A smart pointer is a data type, usually implemented with templates, that simulates a pointer while also providing automatic garbage collection. It automatically counts the number of references to a SmartPointer<?> object and frees the object of type T when the reference count hits zero.Write a Program to define a Mobile class, with member variables o String brand; o double price o String OS (make it Final). o Float memory 1. Make a default constructor, 2. Make a parameterized constructor. 3. Overload the above Constructor. 4. Provide getters and setters for data members. 5. Inside main, create an array of mobiles. 6. Take data from user and set the values for the mobiles in array (check for array out of bound exception). 7. At the end Print data of array using Loop. Programming language : JavaNeed code in C++. I have answer till part 7,please go through the code and correct it if you find any mistakes. If not answer the last 4 parts(8,9,10,11) Create a class called Line with the followings:1. Private members: p1 and p2 as pointer to Point objects (code provided below), slope and length as double variables2. Define setter and getter functions.3. Define a default constructor that allocate dynamic memory for points andset everything to 0.4. Overload a constructor that allocates memory for points, initilize themwith given arguments, and calculate the slope and length.5. Overload a destructor, a copy constructor and a copy assignment operator.6. Create a function called ”parallel” that return true when given lines areparallel and returns false otherwise7. Overload the less than (<) and greater than (>) and equality (==) oper-ators (compare the length)8. Write a functions that reads lines in the format provided in the lines.txtfrom the file and stores them in a vector named…
- Overriding a superclass function means we can change the throws clause. Is this possible?In Kotlin, Use this Employee class: data class Employee(val name: String, val wage: Double, val hours: Double) and this list of Employees: val l: List = listOf(Employee("Bob", 34.33, 42.0), Employee ("Cathy", 27.33, 15.25), Employee("Carlos", 46.99, 38.75), Employee("Tomas", 49.66,28.45), Employee("Xavier", 34.56, 11.5)) a) Write a function called calcBracket that calculates an employee's tax withholding bracket this way: if the Employee's hourly wage is under 15 (in dollars per hour), the withholding bracket is 0; if the wage is at least $15 but under $25, the bracket is .15 (that is, 15%); if the wage is at least $25 but less than $35, the bracket is .25; if th wage is at least $35, the bracket is .35. Return the bracket. b) Write a function that l, takes a list of Employees and f, a function from Double to Double (don't write a call to calcBracket into this function - you will take it as a parameter called f and call f). This function returns a list of Pairs in which each…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…
- Design a class Line that implements a line, which is represented by the formula y = ax+b. Your class should store a and b as double member variables. Write a member function intersect(ℓ) that returns the x coordinateat which this line intersects line ℓ. If the two lines are parallel, then yourfunction should throw an exception Parallel. Write a C++ program thatcreates a number of Line objects and tests each pair for intersection. Yourprogram should print an appropriate error message for parallel lines.Describe Operator Overloading and over load the less than , greater than , equal equal,less than eqaul and greater than equal in c#Write a program which has a class called String containing a character array as a data member. The class should contain constructor for input and an appropriate member function for throwing an exception in case the ASCII value of a character is a palindrome. You may use any other data members or member functions you deem necessary for computing the answer
- Hello, I am having trouble with this homework question for my c++ course. Implement a Rational Number class with the following specifications. Data members a) numerator and denominator Functions a) Constructors: 1) default constructor 2) single parameter constructor to create numerator/1 3) dual parameter constructor to create numerator/denominator 4) Use constructor delegation across all constructors. b) Accessors and Mutators for both data members. c) Static recursive GCD function using Euclid's algorithm. d) Static LCM function for two numbers. e) Reduce function simplify a rational number. This function modifies its calling object. f) Your program should work with the supplied driver program. Notes LCM (Least Common Multiple) This function returns the smallest multiple of a and b. Step 1: Multiply a and b to find a common multiple. Step 2: Divide the common multiple by the GCD of a and b. Step 3: Return the result of Step 2. Reduce: This function reduces a fraction to…T/F 5) If an exception occurs in a catch phrase, then the violation class matches. For instance, if the following catch sentence may catch an exception of the type ArithmeticException as it is running, and then another exception of that type can be thrown inside the same catch blockbe prepared to grab (ArithmeticException e) {Wrap up}1. If a class declaration does not specify extends and a class name to the right of the new class name, the new class does not extend an existing class. Is it True or False? 2. The catch keywords must be used to handle the exception thrown by try block in some rational manners. True or False? 3. A very important fact to remember is that Java does not support multiple inheritance. True or False?
