Question

Write anoyher overloaded constructor for this class. Thr constructor should accept an argumrny for each field. C++ I need help thanks.

Answer 1

I have taken example of employee.

emp.h

#include<iostream>
#include<conio.h>
#include<string.h>
using namespace std;

class employee
{
private: // private data members
   int id;
   char name[20];
   int age;
   char gen[5];
   int sal;

public:
   employee(); //default constructor
   employee(int,const char*,int,const char*,int); //parameterized constructor
   employee(int,int,const char*,const char*,int); //overloaded parameterized constructor
   employee(int,int,int,const char*,const char*); //overloaded parameterized constructor

   void display(); //display function to display all attributes

};

emp.cpp

#include"emp.h"

employee:: employee()
{
this->id=0;
strcpy(this-> name,"\0");
this->age=0;
strcpy(this->gen,"\0");
this->sal=0;

}

employee::employee(int id,const char* name,int age,const char* gen,int sal)

{
this->id=id;
   strcpy(this-> name,name);
   this->age=age;
strcpy(this->gen,gen);
this->sal=sal;

}
employee::employee(int id,int age,const char* name,const char* gen,int sal)

{
this->id=id;
this->age=age;
   strcpy(this-> name,name);
   strcpy(this->gen,gen);
this->sal=sal;

}

employee::employee(int id,int age,int sal,const char* name,const char* gen)
{
this->id=id;
this->age=age;
this->sal=sal;
   strcpy(this-> name,name);
   strcpy(this->gen,gen);

}

void employee::display()
{
cout<<"id is: "<<id<<endl;
cout<<"name is:"<<name<<endl;
   cout<<"age is: "<<age<<endl;
   cout<<"gender is: "<<gen<<endl;
cout<<"salary is: "<<sal<<endl;

}

main.cpp

#include"emp.h"

int main()
{
   employee empl1(123,"vishal",24,"M",45000); //parameterized constructor
   cout<<"Costructor 1: "<<endl;
empl1.display();
cout<<endl;
   employee empl2(124,24,"mohit","M",55000); //overloaded constructor
   cout<<"Overloaded Costructor called : "<<endl;
   empl2.display();
cout<<endl;
   employee empl3(125,24,45000,"sanjana","F"); //overloaded constructor
   cout<<"Overloaded Costructor called : "<<endl;
   empl3.display();

   _getch();

   return 0;
}
