SimpleVector Modification
Modify the SimpleVector class template, presented in this chapter, to include the member functions push_back and pop_back. These functions should emulate the STL vector class member functions of the same name. (See Table 16-4.) The push back function should throw an exception if the array is full. The push_back function should accept an argument and insert its value at the end of the array. The pop_back function should accept no argument and remove the last dement from the array. Test the class with a driver

- 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…arrow_forward. Complete the program to processes an array of structured data. Complete those portions indicated in the template. The program has defined a structure named Sale. The structure has the following fields: string itemName int quantity double unitPrice The main function call loadUserlnput which returns a pointer to the first Sale element in the dynamically allocated array of Sale elements and an integer for the number of Sale elements in the array. The main function then calls printData to show the sale items including the total of cach sale item and the total of the entire list. Function printData This is the function you need to complete as well as two other helper functions. In the function body, print the report heading. Then iterate through the array received through the parameters and print the data according to the required format. For the total of each item, call getltemTotal. At the end of the report, print the total of the entire sale items by calling getTotal.

It checks whether there is a command line argument of “/help” or“/?” or “-help” followed by a topic number. It will print out “yes, topic number(<number>) if there is one. Otherwise, it prints out “no, topic number(N/A) For example, if you run this program with correct arguments as follows, it willprint out yes and its associated topic number respectivelyshowHelp /? 101showHelp /debug /help 102showHelp /print /help 103 /verboseshowHelp -verbose -debug -help And if you run the program with invalid arguments, it will print no, in all casesshowHelp -helpshowHelp 101 /?showHelp 101 102 /help /verboseshowHelp /? /help -helpNote: command line arguments are simply an array of pointers to C-string. example code: #include <iostream> using namespace std; int main(int argc, char** argv){...}arrow_forward

The absolute value of a number is its value with no sign. For example, the absolute value of -5 is 5, and the absolute value of 2 is 2. Test the template in a simple driver program being sure to send the template short, int, double, float, and long data values.arrow_forwardPROGRAMMING LANGUAGE: C++ Write a program which has a class named FileHandlerto read StudentName, MarksObtained from the attached picture. The class should have a function which calculates grade for a student and then adds it in a new column i.e. Grade. The grade should be calculated considering the following criteria. A: 87-100, B+: 80-86, B: 72-79, C+: 66-71, C: 60-65, D: 50-59, F: 0-49 The file should be saved once grade for all students is calculated. Write the driver program for executing the task.arrow_forward
- C++ codearrow_forwardC++ Format Please Write a function (named "Lookup") that takes two const references to vectors. The first vector is a vector of strings. This vector is a list of words. The second parameter is a list of ints. Where each int denotes an index in the first vector. The function should return a string formed by concatenated the words (separated by a space) of the first vector in the order denoted by the second vector. Input of Test Case provided in PDF:arrow_forward1- Define a struct type that contains a person’s name consisting of a first name and a second name, plus the person’s phone number. Use this struct in a program that will allow one or more names and corresponding numbers to be entered and will store the entries in an array of structures. The program should allow a second name to be entered and output all the numbers corresponding to the name, and optionally output all the names with their corresponding numbers. *'Keep the program as simple as possible using the basic logic of struct the following images attached are just for some reference of what simple basic logic means in my words & also supposed to be applied when solving **single pointers & 2d arrays can be usedarrow_forward
- Write a remove member function that accepts an argument for a number of units and removes that number of units of an item from inventory. If the operation is completed successfully it should return the number of units remaining in stock for that item. However, if the number of units passed to the function is less than the number of units in stock, it should not make the removal and should return –1 as an error signal.arrow_forwardClass and Data members: Create a class called Temperature that stores temperature readings (integers) in a vector (do not use an array). The class should have data members that store the month name and year of when the temperature readings were collected. Constructor(s): The class should have a 2-argument constructor that receives the month name and year 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 month and year variables. A member function that adds a single temperature to the vector. Both negative and positive temperatures are allowed. Call this function AddTemperature. A member function to sort the vector in ascending order. Feel free to use the sort function that is available in the algorithm library for sorting vectors.
