Using python pls!!!!! Write a recursive function gcd(m,n) that returns the greatest common divisor of a pair of numbers. The gcd of m and n is the largest number that divides both m and n. If one of the numbers is 0, then the gcd is the other number. If m is greater than or equal to n, then the gcd of m and n is the same as the gcd of n and m-n. If n is greater than m, then the gcd is the same as the gcd of m and n-m.

Pls endevour to use recursive approach to this

C++ Visual Studio 2019

Part A :

Program Description:

Write a program to generate a report based on input received from a text file. Suppose the input text file student_grades.txt contains the student’s Last name , First name, SSN, Test1, Test2, Test3 and Test4. (25%)

i.e.

Alfalfa   Aloysius   123-45-6789 40.0    90.0   100.0    83.0

Generate the output Report File student_final.txt in the following format :

LastName FirstName   SSN Test1   Test2   Test3   Test4 Average FinalGrade

i.e.

Alfalfa   Aloysius   123-45-6789 40.0    90.0   100.0    83.0    78.25 .0   C+

The program must be written to use the enum letterGrade :

enum letterGrade {A_PLUS,A, A_MINUS,B_PLUS,B, B_MINUS, C_PLUS,C, C_MINUS,D_PLUS,D, D_MINUS,F } ;

Use the following function prototype for deriving letter grade :

letterGrade deriveGrade(double average) ;

The average is calculated as follows : (test1 + test2 + test3 + test4)/4.0

The function deriveGrade should derive the letterGrade of the student based on the following grading scale :

Letter Grade

Percentage

GPA

A+

97%+

4.33/4.00 or 4.00/4.00

A

93%-96%

0.00/4.00

Also provide the following function :

         string convertToText(letterGrade grade) ; //This function converts a letterGrade type to a string type.

Requirement :

  • The namespace ‘gradeOpt’ definition should contain the following members :(15%)
    1. the enum letterGrade definition,
    2. deriveGrade(..) function prototype and
    3. convertToText(…) function prototype
  • Add the namespace ‘gradeOpt ‘ to the grade.h header file and the namespace member function definitions to the file grade.cpp file. (10%)

Your assignment is to write a C++ program to read a text file containing the information of the employees of a company, load them into memory and perform some basic human resources operations. This assignment will help you practice: multiple file programming, classes, public and private methods, dynamic memory allocation, constructors and destructors, singly linked list and files.

Implementation

This lab assignment gives you the opportunity to practice creating classes and using dynamic memory in one of the required classes. There are two classes to implement Employee and Company. #the Company will hold a linked list of Employees. This list of employees is modeled using linked nodes of Employee* (pointers to Employees). These employees are created dynamically when they are added to the list.

You will create the following files:

  • menu.cpp: contains your main function
  • employee.h: contains the Employee class declaration
  • employee.cpp: contains the Employee class method definitions
  • company.h: contains the Company class declaration
  • company.cpp: contains the Company class method definitions

Class Descriptions

Employee

Notice there are no changes from previous Employee implementation

Access Member Description
Private _id: unsigned int ID
Private _name: string Name
Private _salary: double Salary
Private _managerId: unsigned int Manager ID
Public Employee(unsigned int, const string&, double, unsigned int=0 Creates an employee using the values given by the parameters. The last parameter represents the manager ID. If the name parameter is an empty string, the constructor should initialize the name to “***”
Public Employee(const Employee&) Copy constructor for Employee
Public GetID(): unsigned int Accessor for ID
Public GetName(): string Accessor for name
Public GetSalary():double Accessor for salary
Public GetManagerId(): unsigned int Accessor for Manager ID
Public ToString():string Returns a string representation of the Employee. (see after the table for the details on this method)
Public Raise(double):void Gives a raise to the employee, adding the specified amount to his or her current salary.
Public Equals(const Employee&) Returns true if the employee specified by the parameter has same ID as current object.
Public Read(istream&):bool Reads an employee from the istream returning true/false depending on whether read was successful.
Public Write(ostream&):void Writes the information about an employee, separated by spaces, to the ostream.
Public ~Employee() Destructor, empty

Company

Access Member Description
Private struct Node{Employee* data; Node* next; } Represents the node type that will become each of the links of the linked list.
Private _head: Node* Head of the list, is the pointer to the first element of the list.
Private _size: unsigned int The number of actual employees in the list. In the beginning, there are no employees.
Private Company(const Company&) Copy constructor private to prevent copies from 'outside' the class.
Public Company() Constructor for Company. Sets the _size to zero, initializes _head to nullptr.
Public AddEmployee(unsigned int, const string&, double, unsigned int=0): bool Adds an employee to the list (to the correct position, the list must always be sorted). The parameters specify the information about the employee. Returns true if it was able to add it, false otherwise.
Public AddEmployee(const Employee&): bool Adds the specified employee to the list(to the correct position, the list must always be sorted). Returns true if it was able to add it, false otherwise.
Public FindById(unsigned int): int Uses binary search to find an employee using the ID given in the parameter. Returns -1 if the employee is not found. If it is found returns the position of that employee.
Public FindByName(const string&, unsigned int=0) Uses linear search starting from the position specified by the second parameter to find the first occurrence of the given name in the Array. Returns -1 if the employee is not found. If it is found returns the position of that employee.
Public Read(istream&):int Reads an istream and extracts all the employees’ data from there, and adds the employees to existing list of employees. Returns the number of employees read.
Public Write(ostream&):int Writes all the available employees to the ostream. Returns the number of employees written.
Public IsFull():bool Always returns false.
Public Get(unsigned int): Employee* Returns a pointer to the Employee at the position specified by the parameter. If the position is invalid, it returns nullptr. The referenced object belongs to the object and should not be “deleted” by the client.
Public GetEmployeeCount():unsigned int Returns the number of employees in the Company (_size)
Public ~Company() Frees the memory by releasing all the dynamically created employees in the array.

Employee::ToString(), returns a formatted string following the following format:

ID: 1 Name: Peter Salary: 250 Manager ID: 0

Widths:

  • ID: 4
  • Name: 10
  • Salary: 10
  • Manager ID: 4

Program Menu

Your program should output the following menu:

1. Load from File
2. Save to File
3. List all Employees
4. Search by Name
5. Search by ID
6. Find Employee Boss Information
7. Add new Employee
8. Check if Database is Full
9. Exit
Menu Option Description
Load a Company File Asks the user for the file name containing the employee’s information. TXT files containing sample company information are included with this Lab document.
Save Company Data to File Saves the current information in memory to a file. The program asks the user for the file name where the user wants to save this.
List all Employees Lists all the employees stored in memory. Uses company ToString method to display them.
Search by Name The user inputs a name, then, using the method FindFirstByName the program displays all employees with that name using ToString method.
Search by ID The user inputs an ID, then, using the method FindById the program displays the employee with that ID using ToString method or that it did not find that ID.
Find Employee Boss Information The user inputs an ID, then, using the method FindById the program displays the employee ID using GetID method or that it did not find that ID. Once the employee is found, gets the manager’s ID, and with it searches that ID and gets the manager’s rest of the information. Displays the manager information using ToString method.
Add New Employee Requests the user to enter the following information about the employee: ID, name, salary and manager ID. Manager ID is zero for employees without boss. Only adds employees if it fits in the array! Only adds employees with ID that is not already in the list
Check if Database is Full Displays a message indicating if the database is full, or not full.
Exit Exits the program

Write a function that removes all even numbers from an array. The function should take the array, length of the array, and a pointer for number of odd numbers found as arguments and return a pointer to the new array. If there are no odd numbers found in the array, your code should print "No odds found." and return NULL.

Use the function header:

int *removeEvens(int *a, int length, int *oddsFound);

Example:

Input array a[ ] = {3, 4, 5, 6, 7}

*oddsFound = 3

return array = {3, 5, 7}

The size of the return array needs to be the number of odd numbers found.

Note: You can determine if a number is even by checking if a[x] % 2 == 0.
