Write a C++ program that: | • Implements a class with three datamembers (szum (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.

Do it in C++ (The MyPoint class) Design a class named MyPoint to represent a point with x- and y-coordinates. The class contains: Two data fields x and y that represent the coordinates. A no-arg constructor that creates a point (0, 0). A constructor that constructs a point with specified coordinates. Two get function for data fields x and y, respectively. A function named distance that returns the distance from this point to another point of the MyPoint Type.Draw the UML diagram the class. Implement the class. Write a test program that creates two points (0, 0) and (10, 30.5) and displays the distance between them.Further create a class named ThreeDPoint to model a point in a three-dimensional space. Let ThreeDPoint be derived from MyPoint with the following additional features: A data field named z that represents the z-coordinate. A no-arg constructor that constructs a point with coordinates (0, 0, 0). A constructor that constructs a point with three specified coordinates. A…

Write a C++ class and choose any name for it. The class should have two privatemembers and two public members. Write a constructor to initialize these membersto zero. Write another constructor to initialize these members to non-zero values.Write a method to return the average of the class members. Write a C++ programand initialize the members of the class with [2,5,8,3] respectively and call its methodto calculate the average.
a. Extend the definition of the class newString as follows:i. Overload the operators + and += to perform the string concatenation operations.ii. Add the function length to return the length of the string.b. Write the definition of the function to implement the operations defined in part a.c. Write a test program to test various operations on the newString objects.
1- Write a class that allows you to define complex numbers in C++ and call it complex. The class contains two private members named real and img. It also has a constructor to initialize its members to values other than zero. Then, write a four methods that implement the basic mathematical operations (+,-.*) for two complex numbers. 2- The purpose of the method resize() in the IntegerArray class below is to dynamically change the size of the IntegerArray instance. This methid is implemented as follows: 1. create a new array with the desired size 2. copy the data form the old to new one 3. delete the old data 4. Make the old data pointer points to the newly created data 5. update the size field your task is to write the resize() method based on the above five steps. #include int main() { using namespace std; IntegerArray a(2); a.data[0] = 4; class IntegerArray { public: a.data[1] = 2; int *data; a.resize(5); int size; cout size = size; solve number 2 } -IntegerArray()) { delete[] data;…
In c++ Please. Given main(), complete class RandomNumbers (in files RandomNumbers.h and RandomNumbers.cpp) that has three integer data members: var1, var2, and var3. Write a getter function for each variable: getVar1(), getVar2() and getVar3(). Then write the following 2 member functions: SetRandomValues( ) - accepts a low and high integer values as parameters, and sets var1, var2, and var3 to random numbers (generated using the random function) within the range of the low and high input values (inclusive). GetRandomValues( ) - prints out the 3 random numbers in the format: "Random values: var1 var2 var3" Ex: If the input is: 15 20 the output is: Random values: 17 15 19 where 17, 15, 19 can be any random numbers within 15 and 20 (inclusive). Note: When submitted, your program will be tested against different input range to verify if the three randomly generated values are within range.

Write a program in java a class Box having three private data members (width, depth, height) The class has three constructors which are having no parameter – for setting values to zero or null. having three parameters for assigning values to height, width, depth respectively. Overload the above constructor and use this keyword to set the values of width, height & depth. Provide getters/setters for data members. Write a function calculateVolume() which calculates the volume of the box. Write test Application that demonstrates the Box class by calling all the three constructors and method, creating a Create Box object, and then displaying the Box’s width , height, length and volume

Write in python. Write a class named Employee that has **private** data members for an employee's name, ID_number, salary, and email_address. It should have an init method that takes four values and uses them to initialize the data members. It should have get methods named get_name, get_ID_number, get_salary, and get_email_address.Write a separate function (not part of the Employee class) named **make_employee_dict** that takes as parameters a list of names, a list of ID numbers, a list of salaries and a list of email addresses (which are all the same length). The function should take the first value of each list and use them to create an Employee object. It should do the same with the second value of each list, etc. to the end of the lists. As it creates these objects, it should add them to a dictionary, where the key is the ID number and the value for that key is the whole Employee object. The function should return the resulting dictionary.For example, it could be used like…
