avaScript NOTE: Dataset is defined below. Using the data set as a pre-defined variable in your program, write code that uses the dataset to print the FIRST NAMES ONLY of people who have BOTH above average English grades AND below average age from the dataset. The solutions for the textbook examples assume you are able to export in a framework like node.js, which is why in the data set I provide, I simply set the array of objects as a variable. Your code will be in the same file (treat it like any other array variable). You can do the same with the sample files the chapter provides. For example:   var ancestry = [   {      .. object ..   },   ... ] // your code here   Requirements: Cannot use any array type built-in functions except filter(), map(), and reduce().   var dataSet = [ { "name":"Maura Glass", "age":60, "math":97, "english":63, "yearsOfEducation":4 }, { "name":"James Gates", "age":55, "math":72, "english":96, "yearsOfEducation":10 }, { "name":"Mills Morris", "age":26, "math":83, "english":77, "yearsOfEducation":10 }, { "name":"Deena Morton", "age":57, "math":63, "english":63, "yearsOfEducation":10 }, { "name":"Edith Roth", "age":38, "math":79, "english":94, "yearsOfEducation":10 }, { "name":"Marva Morse", "age":31, "math":93, "english":78, "yearsOfEducation":9 }, { "name":"Etta Potts", "age":48, "math":57, "english":93, "yearsOfEducation":7 }, { "name":"Tate Moss", "age":22, "math":83, "english":64, "yearsOfEducation":8 }, { "name":"Sanders Burris", "age":27, "math":65, "english":66, "yearsOfEducation":5 }, { "name":"Latoya Malone", "age":35, "math":100, "english":100, "yearsOfEducation":5 }, { "name":"Wade Foreman", "age":25, "math":76, "english":87, "yearsOfEducation":10 }, { "name":"Miller Valentine", "age":31, "math":56, "english":89, "yearsOfEducation":6 }, { "name":"Rita Olson", "age":53, "math":100, "english":52, "yearsOfEducation":6 }, { "name":"Potter Newton", "age":29, "math":91, "english":75, "yearsOfEducation":5 }, { "name":"Madeline Bartlett", "age":23, "math":60, "english":74, "yearsOfEducation":10 }, { "name":"Tamara Tran", "age":46, "math":73, "english":78, "yearsOfEducation":4 }, { "name":"Elena Evans", "age":43, "math":60, "english":82, "yearsOfEducation":10 }, { "name":"Cote Merrill", "age":55, "math":86, "english":63, "yearsOfEducation":7 }, { "name":"Madeleine Brennan", "age":52, "math":82, "english":88, "yearsOfEducation":4 }, { "name":"Alford Weber", "age":38, "math":71, "english":85, "yearsOfEducation":4 }, { "name":"Kirsten Daniel", "age":35, "math":86, "english":61, "yearsOfEducation":8 }, { "name":"Melton Chan", "age":26, "math":55, "english":96, "yearsOfEducation":4 }, { "name":"Mcmahon Woodward", "age":54, "math":56, "english":63, "yearsOfEducation":9 }, { "name":"Helga Monroe", "age":29, "math":79, "english":92, "yearsOfEducation":5 }, { "name":"Patricia Herrera", "age":46, "math":94, "english":99, "yearsOfEducation":10 }, { "name":"Mccullough Lambert", "age":56, "math":65, "english":96, "yearsOfEducation":8 }, { "name":"Haynes Davidson", "age":60, "math":86, "english":50, "yearsOfEducation":5 } ]

Write a C++ program define a vector object and initialize it with 3 values and then define an iterator that points to elements of this object, then ask the user to enter 3 more values and then add them to the previous vector and then print all elements in the vector.

A pointer variable is just what it sounds like. What is its purpose? Exactly what does it mean to have a "dynamic array"? Pointers and dynamic arrays have what relationship?

Classes, Objects, Pointers and Dynamic Memory Program Description: This assignment you will need to create your own string class. For the name of the class, use your initials from your name.  The MYString objects will hold a cstring and allow it to be used and changed. We will be changing this class over the next couple programs, to be adding more features to it (and correcting some problems that the program has in this simple version). Your MYString class needs to be written using the .h and .cpp format. Inside the class we will have the following data members: Member Data Description char * str pointer to dynamic memory for storing the string int cap size of the memory that is available to be used(start with 20 char's and then double it whenever this is not enough) int end index of the end of the string (the '\0' char) The class will store the string in dynamic memory that is pointed to with the pointer. When you first create an MYString object you should…

What is the difference between the size and capacity of a vector?

You are required to write a program that creates a mini database of HairColor objects..... For this, create a structure HairColor with fields brand – string color - string price - float totalVolume – float currentVolume – float // amount of volume currently available. You need to provide following functions in the struct   Provide a function print() so that when called, this function prints the details about the Hair color in formatted manner. IsAvailable(String Technique) which checks the volume of color in the bottle if available for the required technique then returns true otherwise false. isEmpty() this will check whether the bottle is empty or not. You need to provide the function apply (String technique). This function represents the action of applying hair color to hair based on technique user selects Techniques are (highlight, Bronde, Ombre, Sombre) also note down please check that the color is available because volume required for each type of technique is different as for…
