Question

Antique Class

Each Antique object being sold by a Merchant and will have the following attributes:

• name (string)
• price (float)

And will have the following member functions:

• mutators (setName, setPrice)
• accessors (getName, getPrice)
• default constructor that sets name to "" (blank string) and price to 0 when a new Antique object is created
• a function toString that returns a string with the antique information in the following format

<Antique.name>: $<price.2digits>

Merchant Class

A Merchant class will be able to hold 10 different Antique objects and interact with the user to sell to them. It should include the following attributes:

• antiques (array): An Antique array of 10 objects
• quantities (array): An Integer array representing the quantity of each Antique object in stock. This can range from 0 to 10.
• revenue (float): variable used to store the total amount of money earned by the Merchant after each sale

And will have the following member functions:

• Merchant (constructor): the constructor takes as arguments an array of Antiques and an array of quantities to use them to initialize antiques and quantities. revenue should be set to 0.
• haggle: function that decreases each and every Antique object's price by 10%. It will print the following:

You have successfully haggled and everything is 10% off.

Customer cannot haggle more than once. If he tries to haggle more than once, it will print the following:

Sorry, you have already haggled.

Answer 1

The code is below:-

#include <iostream>

#include <string>

using namespace std;

class Antique { // The class

public: // Access specifier

string name; // Attribute (string variable)

float price; // Attribute (float variable)

Antique(){

name="";

price = 0;

}

string getName(){

return name;

}

void setName(string userName){

name = userName;

}

float getPrice(){

return price;

}

void setPrice(float itemPrice){

price = itemPrice;

}

string toString(){

float value = (int)(price * 100 + .5);

float temp1 = (float)value / 100;

string temp = "Name: "+name+" Price: "+ to_string(temp1);

return temp;

}

};

class Merchent{

Antique *arr;

int *quantities;

float revenue;

public:

Merchent(Antique a[10],int q[10]){

arr = a;

quantities = q;

revenue=0;

}

int haggleUsed = 0;

void haggle() {

if (haggleUsed == 1) { // checking if it's value if 1 then not changing anything

cout<<"Sorry, you have already haggled."<<endl;

} else {

for (int i = 0; i < 10; i++) { // else decreasing the price by 10 percent

float temp = arr[i].getPrice();

temp = temp - (float) (temp * 0.10);

arr[i].setPrice(temp);

cout<<"haggle "<<arr[i].getPrice()<<endl;

haggleUsed = 1;

}

}

}

};

int main() {

Antique an[10];

an[0].setName("Rishab");

an[0].setPrice(45.56);

an[1].setName("qwert");

an[1].setPrice(5.56);

an[2].setName("zxcv");

an[2].setPrice(74.56);

an[3].setName("wscde");

an[3].setPrice(65.56);

an[4].setName("polkij");

an[4].setPrice(25.56);

an[5].setName("yhnmju");

an[5].setPrice(98.56);

an[6].setName("efbrgn");

an[6].setPrice(64.56);

an[7].setName("fjbgh");

an[7].setPrice(10.56);

an[8].setName("yhjur");

an[8].setPrice(35.56);

an[9].setName("asdbteh");

an[9].setPrice(30.56);

int quantity[]={1,2,3,4,5,6,7,8,9,10};

Merchent mr(an,quantity);

mr.haggle();

for(int i=0;i<10;i++){

cout<<an[i].getPrice()<<endl;

}

mr.haggle();

}
