  Exercise 1:
  Make a C language algorithm to calculate how much each customer has spent on
  orders placed in a snack bar. The snack bar sells the following products:

  Item Product 		Code 	Price Unit
  1 Hot Dog 		100 	5.00
  2 X-salad 		101 	8.79
  3 X-bacon 		102 	9.99
  4 Mixed 		103 	6.89
  5 Salad 		104 	4.80
  6 Water 		105 	3.49
  7 Soda	 	106 	4.99

  Requirements:
  
  When starting the program, a menu with all items sold must appear on the screen  
  and their respective prices. The user must choose by typing from 1-7 which item
  want to buy.
  Note that the user can purchase the same item several times and can also
  buy several different items (example: 2 waters and a hot dog, in the same
  request).
  To end the purchase process, the user must enter a value other than 1-7. 
  At the end of the purchase, you must list all the items purchased, their individual prices
  and the total to be paid.
