Question

Write a code in C++ by considering the following conditions :-

Tasks :-

1. Create a class Employee (with member variables: char * name, int id, and double age).
2. Create a constructor that should be able to take arguments and initialize the member
variables.
3. Create a copy constructor for employee class to ensure deep copy.
4. Create a destructor and de allocate the dynamic memory.
5. Overload the assignment operator to prevent shallow copy and ensure deep copy.
6. Overload the stream insertion operator << to print the values of member variables.
7. Use of constant reference parameters is mandatory
8. Test the functionality of class in main function.
Note : Use of this pointer is mandatory where required. You are not allowed to use any cin and cout
in implementation of functions except in task 6.

USE strcpy_s instead of strcpy because the second one is not working in my case.

-> The class definition for the code is probably as under. Please follow the desired pattern :-

class Employee
{
private:
int id = 0;
double age = 0;
char* name;
public:
Employee(char * name, int id, double age); // This is constructor.
Employee(const Employee&); // This is Overloaded constructor.
~Employee(); // This is Destructor.
// Overload assignment operator here.
// Overload " << " here to print Employee.
};

*** Apply all proper Testing cases or Checks in each case.

Test the destructor also. All the tests must be present in the main.

Thanks in Advance.

Answer 1

#include<iostream.h>

struct Employee
{
int Id;
char Name[25];
int Age;
long Salary;
};

void main()
{

Employee E; //Statement 1

cout << "\nEnter Employee Id : ";
cin >> E.Id;

cout << "\nEnter Employee Name : ";
cin >> E.Name;

cout << "\nEnter Employee Age : ";
cin >> E.Age;

cout << "\nEnter Employee Salary : ";
cin >> E.Salary;

cout << "\n\nEmployee Id : " << E.Id;
cout << "\nEmployee Name : " << E.Name;
cout << "\nEmployee Age : " << E.Age;
cout << "\nEmployee Salary : " << E.Salary;

}

Output :

Enter Employee Id : 1
Enter Employee Name : Kumar
Enter Employee Age : 29
Enter Employee Salary : 45000

Employee Id : 1
Employee Name : Kumar
Employee Age : 29
Employee Salary : 45000
