Answer to Question #201095 in C++ for hammad

Question

Define a class named Customer that holds private fields for a customer ID number, last name, first name, and credit limit. Include four public functions that each set one of the four fields. Do not allow any credit limit over $10,000. Include a public function that displays a Customer’s data. Write a main()function in which you declare a Customer, set the Customer’s fields, and display the results.

#include <iostream>


using namespace std;


class Customer
{
private:
    int ID;
    string lastname;
    string firstname;
    double creditLimit;


public:
    void setID(int ID)
    {
        this->ID = ID;
    }
    void setLastname(string lastname)
    {
        this->lastname = lastname;
    }
    void setFirstname(string firstname)
    {
        this->firstname = firstname;
    }
    void setCreditLimit(double creditLimit)
    {
        this->creditLimit = creditLimit;
    }


    void displayInfo()
    {
        cout << "ID: " << ID << endl;
        cout << "last name: " << lastname << endl;
        cout << "first name: " << firstname << endl;
        cout << "credit limit: " << creditLimit << "$" << endl;
    }
};


int main()
{
    Customer customer;


    cout << "ID = ";
    int ID;
    cin >> ID;
    customer.setID(ID);
    cin.get();


    cout << "Enter first name: ";
    string firstname;
    getline(cin, firstname);
    customer.setFirstname(firstname);


    cout << "Enter last name: ";
    string lastname;
    getline(cin, lastname);
    customer.setLastname(lastname);


    double credit_limit;
    do
    {
        cout << "Enter credit limit: ";
        cin >> credit_limit;
        if(credit_limit > 10000)
            cout << "credit limit over 10000$ not allowed" << endl << endl;


    }while(credit_limit > 10000);


    cout << endl;
    customer.setCreditLimit(credit_limit);
    customer.displayInfo();


    return 0;
