(C++) Construct a Customer class that keeps track of a Customer purchases, credit line, and total balance. An object in the Customer class will have a name, an address, a credit limit (set to $1500) as well as other data fields. Declare and define data fields, include a constructor to populate the data fields, and implement member functions such that you can perform the following:
• Extract data members if needed.
• Keep track of number of sales, and total balance.
• Specify if a new purchase would exceed the credit limit. If the cost of an item to be purchased, added to the unpaid balance, surpasses the Customer’s credit limit , do not allow the sale and output “Not enough credit limit.Purchase cannot be completed.” . Otherwise show “Purchase successful.”
Write a program that tests the features of the Customer class. Figure 1 shows a sample output. You can use the following pseudocode as a template:
#include header files
using namespace std;
class Customer
{public:
Customer(parameters);
string get_name() const;
double get_credit_limit() const;
double get_total_balance() const;
int get_num_purchases() const;
Private:
//data field};
//definition of constructor and member functions
int main()
{
construct Customer object
cout << “Customer: ” << Customer name << endl;
cout << “Credit Limit: ” << Customer credit imit << endl;
//while loop
purchase value?
cin >> val;
c.add_purchase (val);
Purchase another item (y/n)?
cout << “The total of ” << number of purchases << “purchase(s) is $ ” << total balance << endl;
return 0;
}
