#c++# Write a program that inputs a line of text, replaces all punctuation marks with spaces. 2.Create a class called Complex for performing arithmetic with complex numbers. Write a program to test your class. Complex numbers have the form realPart + imaginaryPart * i where i is Use double variables to represent the private data of the class. Provide a constructor that enables an object of this class to be initialized when it’s declared. The constructor should contain default values in case no initializers are provided. Provide public member functions that perform the following tasks: Adding two Complex numbers: The real parts are added together and the imaginary parts are added together. Subtracting two Complex numbers: The real part of the right operand is subtracted from the real part of the left operand, and the imaginary part of the right operand is subtracted from the imaginary part of the left operand. Printing Complex numbers in the form (a, b), where a is the real…

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 : Java
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…
Implement the Rectangle class as discussed this week. Use the class declaration below. Your job is to implement the functions. Implement the missing functions yourself. class Rectangle{ private: double width; double length; char *name; void initName(char *); public://constructorsRectangle();Rectangle(double, double, char*);//destructor ~Rectangle(); void setWidth(double); void setLength(double); void setWidth(char *); void setLength(char *); void setName(char *); double getWidth() const; double getLength() const; void printName() const { cout << name; }}; A few notes on the functions: initName(char *): this is a private member function. It should be the only function which dynamically allocates a char array to hold the name. setName(char *): this is a public member function which changes the name of the rectangle to a new name. It does not dynamically allocate memory, it only changes name. Demonstrate your class works…

With the coding below ,Complete the part labelled ‘//2 a) i’, write the constructor function that outputs “~~Building Created~~” and labelled //2 a) ii’, write the codes to define function findLargest(…). This function will receive an array of 5 Room objects and display the area width x length) of each object. The largest room area will be determined and displayed accordingly. #include <iostream> using namespace std; class Room { int width, length; public: // 2 a)to complete void setData (int L, int T) { width = L; length = T; } friend class Building; } ; class Building { string name; public: Building() { name = "Building"; cout<<"----Buiding name : "<<name<<"-------"<<endl; } // 2 a)to complete }; int main() { Building B1; Room r[5]; int i = 0, x, y; while( i < 5 ) { cout<<"Enter the tables' width and length :\n"; cin>>x>>y; r[i]. setData(x,y); i++; } B1.findLargest(r); return 0; }
