2. On the purchase of two items, bill amount will be of the item having the higher price.
3. On the purchase of three items, bill amount will be the sum of highest and lowest price.
Create a class SHOP having three overloaded methods named billAmount()……..{with parameter with
return type.}
Create another class containing main method and generate the bill for above given situations





My Code


#include<iostream.h>
#include<conio.h>

class Shop
{
private:
int item;
float price,p1,p2,p3;

public:
float billAmount(float p);
float billAmount(float p,float x);
float billAmount(float p,float x,float y);
};
float Shop::billAmount(float p)
{
price=p;
item=1;
cout<<"no offer on the purchase of 1 item,cost:"<<price;
return (price);
}
float Shop::billAmount(float p,float x)
{
p1=p;
p2=x;
item=2;
if(p1>p2)
{
cout<<"On the purchase of two items, bill amount will be of the item having the higher price.cost:"<<p1;
return (p1);
}
else
{
cout<<"On the purchase of two items, bill amount will be of the item having the higher price.cost:"<<p2;
