Create a class or struct called Display. The class or struct should overload the operator() function and accept an integer and displays that argument value. (C++)
#include <iostream> using namespace std; class Display { public: void operator()(int n) { cout << n << endl; } }; int main() { Display d; d(100); d(17); d(94); return 0; }

2. Overload a function "display" so that (a) if display is called with a string, it prints the string 5 times and then returns the length of the string (b) if it is called with an integer, n, it prints n, 2n, 3n and has no return value (c) if it is called with a character, it prints the character on the first line, 2 of the character on the 2nd line, 3 of it on the 3rd line and...
Question 3: Q3 (Polymorphism & virtual function) a) Consider the class, derived class, and the virtual functions as shown in Display for Q3. Create a derived class (of Sale) called 'MailorderSale' having one private member variable called 'shipping charge'. It should have constructor function and virtual function 'bill' (this function adds shipping charge to the price). Define all these functions (no need of default constructors). b) In the main function, define one object of DiscountSale with (11,10) initial values and...
How do overload the relational operator == for the class stackType that returns true if two stacks of the same type are the same, false otherwise. Also write thedefintion of the function template to overload this operator.
Overload a relational operator for the Job class: Assume that this operator is not overloaded for the Salary class. a) Write how the function will be declared in your code. b) Write an external function definition (not inside the class). solve it in C++10 to solve this you nedd question number 1. Create a composition between the classes Job and Salary. Class Salary a. data member: 1. money b. constructors: 1. default constructor 2. user defined constructor with a parameter...
In C++ Create a class called MyInteger. It should have a field of type pointer-to-int called pInteger. It should have a constructor that takes as a parameter an int - the constructor will then dynamically allocate memory for an int, using pInteger, and assign the parameter's value to that memory. The class should have a destructor that will deallocate that memory when the object is destroyed. You should write a copy constructor that will correctly make a separate copy of...
Write a class called Book that has two private member variables called page (integer) and topic (string). It also has a static private member variable called count (integer). This class has only one constructor with default argument for page and topic. Write this constructor. Also overload the addition operator for this class such that it will add an integer value to the page variable of the book. For example when in main we say: book2 = book1 + 4; then...
REQUIREMENTS: Problem Description: Create a Dynamic 2D Array Class. This class should overload the Call Operator () for the following behaviors: Return (modifiable) Lvalue element for a non-const object Return (read-only) Rvalue element for a const object Return a copy of the data values for row Return a copy of all the data as a 1D vector Create a TestScores Class which uses a Dynamic 2D Array object as an internal data structure. This class should have the following behaviors:...
QUESTION 18 According to class materials, the program is allowed to overload operators only if at least one incoming parameter received by the operator has a class type. 1. (a) True 2. (b) False QUESTION 19 According to the course materials, a function can take value parameters and reference parameters. A value parameter is a separate variable from the one in main() or another calling function only if the function value parameter has a different name than the one in...
CE – Return and Overload in C++ You are going to create a rudimentary calculator. The program should call a function to display a menu of three options: 1 – Integer Math 2 – Double Math 3 – Exit Program The program must test that the user enters in a valid menu option. If they do not, the program must display an error message and allow the user to reenter the selection. Once valid, the function must return the option...
