Write a 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

T or F -Functions are considered to be objects in JavaScript because they contain three critical attributes: data, methods that act on the data, parameters for passing the data also known as awareness. -A recursive function is a function that calls itself and eventually returns default value to break out of the recursion. -A function that is used to create a new object is called an anonymous function. -Attributes define additional characteristics or properties of the element which is the same as for the start tag. -Javascript is similar to the Java programming language

Write the c++ program as follows, 1- Create a class Employee with id(int type), name(string type) and points(double type) as private data member. 2-Create a 2 arguments constructor with id and name as arguments. 3-Create a function addPoints to adjust the value of points. 4-Create a static function getBest that return the id of Employee with maximum points. 5-Create a function display to print all the attributes. 6-In main create 5 objects of class Employee using an array and initialize it. 7-Call the function addPoints and add 500,300,400,600,100 points to each object. 8-Call the function getBest. 9-Call the function display.

Write a C++ program to create a class named 'student' with attributes as; the name of the student and marks obtained by the student. The class should include 2 member functions as; a function to input the student's name and marks scored. a function to display the student's name and marks scored. Your program should then display the student's name who has scored maximum marks in the main code. Note: It is mandatory to create a class, with its member functions.
create using c++ One problem with dynamic arrays is that once the array is created using the new operator the size cannot be changed. For example, you might want to add or delete entries from the array similar to the behavior of a vector . This project asks you to create a class called DynamicStringArray that includes member functions that allow it to emulate the behavior of a vector of strings. The class should have the following A private member variable called dynamicArray that references a dynamic array of type string. A private member variable called size that holds the number of entries in the array. A default constructor that sets the dynamic array to NULL and sets size to 0. A function that returns size . A function named addEntry that takes a string as input. The function should create a new dynamic array one element larger than dynamicArray , copy all elements from dynamicArray into the new array, add the new string onto the end of the new array, increment size, delete the…
java language A system needs to have a Validation class that can validate the input for instance variables ofthe different classes given in Table 1. It should validate the values for the data members from different classesusing Regular Expressions, such that a name can only contain alphabets from A to Z or a to z and the firstletter is always a capital letter. The address should start with a number followed by one or two words (forexample 16 Khyber or 16 Khyber Ave). The phone number should have a format like 0-000-0000000 where the first digit is always a 0. The e-mail address should contain exactly one ‘@’ character and at least one ‘.’character. A car’s registration number can only contain a maximum of 3 English alphabets followed by notmore than 4 digits. All the classes should be able to validate their data without creating the objects
