Write a program that demonstrates default argumented constructor function

Write a program that demonstrates default argumented constructor function. The program uses the following properties – class names- staff; private members: char *name, char gender, int age, long salary ; public: staff( char *n, char g, int a, long s), details(); Constructor function staff( char *n, char g, int a=40, long s=4500) sets the values from object and with default values. details() function displays staff details as name, gender, age salary. The program uses two parameterized objects.First object displays staff details with all default values. Second object displays staff details with all new values.

#include<iostream>

using namespace std;

class staff

{

    char *name;

    char gender;

    int age;

    long salary;

public:

    staff(char *n,char g,int a,long s);

    void details();

};

staff::staff(char *n,char g,int a=40,long s=4500)

        {

          name=n;

          gender=g;

          age=a;

          salary=s;

        }

void staff::details()

            {

                cout<<"Name is : "<<name<<endl;

                cout<<"Gender is : "<<gender<<endl;

                cout<<"Age is : "<<age<<endl;

                cout<<"Salary is : "<<salary<<endl;

            }

 int main()

 {

     staff s1("solaiman",'M');

     s1.details();

     staff s2("Ratan",'M',20,15000);

     s2.details()

  return 0;

 }
