Question
C++:
Part a. Create an overloaded constructor for a derived class named CustomerData
- Create the function without rewriting code from the overloaded base class constructor.
- Base Class (PersonData):
- A member variable for lastName, firstName and address (strings)
- Overloaded constructor
- Derived Class (CustomerData):
- A member variable for customer number (int)
- A member variable for mailing list (bool)
Part b. Using the information above, create an overloaded operator function to determine if a customer is less than another customer. A customer should be less than another customer if the customer number is less than the other customer number.
Explanation / Answer
#include<iostream>
#include<string>
class PersonData
{
public:
PersonData(string l, string n, string a)
{
lastName=l;
firstName=n;
address=a;
}
string toString()
{
string s= lastName+" "+firstName+" "+address;
return s;
}
private:
string lastName, firstName,address;
string y;
};
class CustomerData: public PersonData
{
public:
CustomerData(string l, string n, string a, int id) : PersonData(l,n,a)
{
customer_no=id;
}
// overload < operator
bool operator<(CustomerData& c) const
{
if(customer_no < c.customer_no) return true;
else return false;
}
int getCustomerNo()
{
return customer_no;
}
private:
int customer_no;
};
int main()
{
CustomerData c("Khan","Asif","batamaloo", 1);
CustomerData c1("Sheikh","Junaid","Habbakada;", 2);
CustomerData c2("Khan","Asif","batamaloo", 1);
if(c<c1)
{
cout << c.toString() <<" is less than "<<c1.toString();
}
else cout << c.toString() <<" is not less than "<<c1.toString();
}
