The program has to be in c++ Can someone help with this program? Create a Student class with member-data name and average success and member-functions • Designers • get & set • member-function (method), returning the first letter of the student's name Write external functions with a vector parameter from students • To read a list of Student objects (vector ) from a file (the file is submitted as a second parameter) • To display a list of students on the screen • To calculate the average success of a list of students Write two sorting functions - by name and by average success

What are the values of the variable number and the vector review after the following code segment is executed? vector<int> review(10,-1); int number; number = review[0]; review[1] = 150; review[2] = 350; review[3] = 450; review.push_back(550); review.push_back(650); number += review[review.size()-1]; review.pop_back();

C++ Program For this program you’ll write a simple class and use it in a vector.Begin by writing a Student class. The public section has the following methods: Student::Student()Constructor. Initializes all data elements: name to empty string(s), numeric variables to 0. bool Student::ReadData(istream& in)Data input. The istream should already be open. Reads the following data, in this order: First name (a string, 1 word) Last name (also a string, also 1 word) 5 quiz scores (integers, range 0-20) 3 exam scores (integers, range 0-100) Assumes that all data is separated by whitespace. The method returns true if reading all data was successful, otherwise returns false. Does not need to validate or range-check data; if one of the quiz or exam scores is out of range, just keep going. bool Student::WriteData(ostream& out) constOutput function. Writes data in the following format. Each student’s data is on one line. • First name (left justified, 20 characters)• Last name (left...

Every data structure that we use in computer science has its weaknesses and strengthsHaving a full understanding of each will help make us better programmers!For this experiment, let's work with STL vectors and STL dequesFull requirements descriptions are found in the source code file Part 1Work with inserting elements at the front of a vector and a deque (30%) Part 2Work with inserting elements at the back of a vector and a deque (30%) Part 3Work with inserting elements in the middle, and removing elements from, a vector and a deque (40%) Please make sure to put your code specifically where it is asked for, and no where elseDo not modify any of the code you already see in the template file This C++ source code file is required to complete this problem

Description You are provided a skeleton code in the file student_code.c. Some functions are completely implemented, and some are partially implemented. Additionally, you can add your own functions if required. Complete the program as per following details so that we can have functionality as described in the Synopsis above. All the code in single C file. REMEMBER DO NOT USE sleep(). 1. The given code reads the file's content for you and populates a dynamic array of type struct thread with information about the threads. The threads have filled in this list of threads for you. Additionally, you can check the threadCount variable to see how many threads were created using the input file. If more members are needed, you can add them. You might be able to initialise those extra members during file read if you wish to. 2. The main() already contains the code to read threads from input file. However, there is no code to initialize, execute and synchronize threads. You have to perform these...

In C++ Write a code snippet to automatically increase the size of the dynamic array playerToolbox[10] if it becomes full while reading data in from a file.

code in c program

1) Define a global variable Emps that is an array of pointers to employee structs. 2) Change your createEmployee function to add the new employee to the Emps array. It should place it in the first slot that contains a NULL. 3) Write a listEmployees function that will call your display function on each employee in the array. 4) Change main to have a loop that looks for user commands. • If the user types HIRE, you should call createEmployee. If the user types LIST, you should call listEmployees. • If the user types QUIT, you should exit the loop, which will then cause the program to exit. 5) Write a findEmployee function that takes a string parameter and returns the employee pointer with that name or NULL if no such person exists. Change main to add a FIND name command that will find and display a single employee.

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...
