C++ code

Please let me know how to write the code without using malloc, sizeof and free

  Provided for you in the department.h. It represents the maximum number of characters in a project's topic. Struct Project This struct is provided for you in department.h. It represents a project which a department can work on. A project will have a topic represented by a C string that can hold a max of 25 characters. A project also has double that represents its cost. Your task for part one of workshop 3 is to create a class called "Department" that encapsulates a Project. (in Department.h and Department.cpp). Attributes The Department class must keep the following information: - The departments' name: that is held dynamically in a C string. - The departments' projects: that is held dynamically by a Project pointer. - Number of Current Projects: that are all held in an integer. ( int ) - Budget of the Department: that is held in a double Should have an initial value of 15345.99. Public methods The Department class has the following Public functions: void updateName (const char* newname) If the provided name is valid (exists and is not empty), this function will set the name of the department. If the department is already set, it will deallocate the name. It will create enough memory for the name of the department to match the new name and then copies the data of the new name. If the new name is not valid, the department's current name will not change. This function will update the budget of the department by adding a new change to it. bool addproject(Project\& newproject) This function will add a new project to the department as long as the total cost does not exceed the allocated budget. If the new project cost in addition to the total cost of the current project does not exceed the budget this function will add the new project to the department list of projects by doing the following steps: - if there are no projects currently in progress: creates a new Project and saves the data inside it - if there are projects currently in progress: allocates a temp array of projects with new size = old size +1. copy all projects from the old array to the new one add new data to the last position of the temp array wipe out the old array increase the number of the project by one allocate projects with the new size copy all projects from the temp array to projects - wipe out the temp array - This function will eventually return true if a project was added to the department, and false otherwise. void createdepartment (const char* newname, Project\& newproject, double change); This function will use functions updateName, addProject and updateBudget to set the name of the department, add a project to it and update its budget. Project* fetchProjects() const int fetchNumProjects() const; This function will return the number of projects a department is currently working on. double fetchBudget() const This function will return the current budget of a department. char* Department: : fetchName() const This function will return the name of a department. double totalexpenses() This function will calculate and return the expenses of a department. The total expenses of a department is the total cost of all its current projects. double remainingBudget() This function will calculate and return the remaining budget of a department by subtracting the total expenses from the budget. void clearDepartment() This function will clear all the dynamic memory allocation in a department. Helper Functions These functions are fully provided for you, make sure you review them and understand how they work: void display (const Project\& project) This function will Display the details of a project. This function will Display the details of a department.
