void getVectorSize(int& size); void readData(vector<Highscore>& scores); void sortData(vector<Highscore>& scores); vector<Highscore>::iterator findLocationOfLargest( const vector<Highscore>::iterator startingLocation, const vector<Highscore>::iterator endingLocation); void displayData(const vector<Highscore>& scores); The size parameter from the given code won't be needed now, since a vector knows its own size. Notice that the findLocationOfLargest() function does not need the vector itself as a parameter, since you can access the vector using the provided iterator parameters. The name field in the struct must still be a c-string The focus of this assignment is to use iterators. You must use iterators wherever possible to access the vector. As a result, you must not use square brackets, the push_back() function, the at() function, etc. Also, the word "index" shouldn't appear in your code anywhere. You won't get full credit if…

Procedure: Develop an extension of structure.Vector, called MyVector, that includes a new method, sort. Here are some steps toward implementing this new class: 1. Create a new class, MyVector, which is declared to be an extension of the structure.Vector class. You should write a default constructor for this class that simply calls super();. This will force the structure.Vector constructor to be called. This, in turn, will initialize the protected fields of the Vector class. 2. Construct a new Vector method called sort. It should have the following declaration: public void sort(Comparator c) // pre: c is a valid comparator // post: sorts this vector in order determined by c This method uses a Comparator type object to actually perform a sort of the values in MyVector. You may use any sort that you like. 3. Write an application that reads in a data file with several fields, and, depending

Class and Data members: Create a class called Student that stores a student’s grades (integers) in a vector (do not use an array). The class should have data members that store a student’s name and course for which the grades are earned. Constructor(s): The class should have a 2-argument constructor that receives the student’s name and course as parameters and sets the appropriate data members to these values. Member Functions: The class should have functions as follows: Member functions to set and get the student’s name and course variables. A member function that adds a single grade to the vector. Only positive grades are allowed. Call this function AddGrade. A member function to sort the vector in ascending order. A member function to compute the average (x̄) of the grades in the vector. The formula for calculating an average is x̄ = ∑xi / n where xi is the value of each grade and n is the total number of grades in the vector. A member function to determine the lowest…
True/ False 1- Class objects can be defined prior to the class declaration. 2- You must use the private access specification for all data members of a class. 3- If an array is partially initialized, the uninitialized elements will be set to zero. 4- A vector object automatically expands in size to accommodate the items stored in it. 5- With pointer variables, you can access but not modify data in other variables. 6- Assuming myValues is an array of int values and index is an int variable, both of the following statements do the same thing. 1. cout header file. 15- To solve a problem recursively, you must identify at least one case in which the problem can be solved without recursion.

Objects and Pointers Write code to instantiate/create two Bicycle objects: a default object (my_bike) and a non-default object (sister_bike). For the non-default object you may hard-code (or make up) the required parameters (brand, price and wheel size). No console input is needed.
Question 2 You are about to create a simple 2D shooting game. i) Create appropriate structures with the following information: Bullet isAvailable: bool Gun type: The gun type (e.g. Rifles or Pistol) bulletSize: Total bullets in the gun (e.g. 6 bullets in Pistol) bullets: An array of Bullet type. Maximum 100 bullets applied in the game. ii) Assume you have defined a variable called myWeapon as follows: Gun myWeapon; myWeapon.model "Machine Gun"; myWeapon.size 80; Write a code fragment to reload all the gun bullets status to true. iii) Create a function called shot that takes in a reference parameter as Gun type. The function displays the message "Reload" if the first bullet is empty. Otherwise, for every single bullet, it displays "Bang" and set the last bullet to false.
Create an Organization class. Organization has 10 Employees (Hint: You will need an array of pointers to Employee class) Organization can calculate the total amount to be paid to all employees Organization can print the details(name & salary) of all employees note: write code in main,header and function.cpp file
Smart Pointer: Write a smart pointer class. A smart pointer is a data type, usually implemented with templates, that simulates a pointer while also providing automatic garbage collection. It automatically counts the number of references to a SmartPointer<?> object and frees the object of type T when the reference count hits zero.
