Question

Problem 2: Point of Sale System
The McDowell Restaurant chain has asked you to write a menu program for their new Fast-food
service machines. Your program already prints the following menu like this:
**********************************************************************
McDowell’s Restaurant
**********************************************************************
Make your selection from the menu below:
1. Regular Hamburger $1.50
2. Regular Cheeseburger $1.75
3. Fish Sandwich $2.50
4. Half-pounder with cheese $2.75
5. French Fries $0.99
6. Large Soft Drink $1.25
***********************************************************************
Select 1, 2, 3, 4, 5, or 6 ----- >
Your program must now read the customer’s selection and compute the total price of their
purchase, including 6.5% sales tax.
Input
The first line of input represents N, the number of test cases. The additional lines consists of a
sequence of integers scoped between 1 to 6. Each number should indicate a selection from the
above menu to be purchased.
Output
The program should print the sum of the orders plus tax as “Please pay $<dollars>”, where
<dollar> is the total amount of the purchase then conclude with “Thank you for eating at
McDowell’s”.

Sample Input Sample Output
1
1 4 4 5 3 1 Please pay $12.77
Thank you for eating at McDowell’s!

float total_without_taxes=0,total_with_taxes=0,val;
cout<<"**********************************************************************\n";
cout<<"McDowell’s Restaurant\n";
cout<<"**********************************************************************\n";
cout<<"Make your selection from the menu below:\n";

cout<<"Select 1, 2, 3, 4, 5, or 6 ----- >\n";
cin>>n;
for(int i=0;i<n;++i)
{
cin>>choice[i];
}
total_without_taxes=0.0;
for(int i=0;i<n;++i)
{
if(choice[i]==1)
val=1.5;
else if(choice[i]==2)
val=1.75;
else if(choice[i]==3)
val=2.5;
else if(choice[i]==4)
val=2.75;
else if(choice[i]==5)
val=0.99;
else if(choice[i]==6)
val=1.25;
total_without_taxes+=val;

}
total_with_taxes=total_without_taxes*1.065;
printf("Please pay $%.2f\n",total_with_taxes);
cout<<"Thank you for eating at McDowell's!";
}
