COSI 216: Programming in C++
The purposes of this assignment are to know 
   - how to use a nested if/else statement 
   - how to set up a while loop
   - how to accumulate a total price.  
       That is,  initialize total as zero and accumulate price as
        total = total + price;
A restaurant charges a meal in the following rules:
If a child is under 13 years old, he/she pays 25 cents per year of his/her age.
If a child is 13 or older and 17 or younger, he/she pays $6.
A senior who is 60 or older pays $6.
Regular adults pay $10.

Write a program to calculate the total payment for a family meal.

Basically, you should decide how many memory boxes you need and draw a flowchart before you type your codes into computers.

For example, a family has 6 members and the ages are 3, 7, 15, 35, 37 and 60.
You will have the following interface with user:
Enter 0 to terminate the program

	Age	Price	Total
Enter age:	3
		0.75	0.75
Enter age:	7
		1.75	2.50
Enter age:	15
		6.00	8.50
Enter age:	35
		10.00	18.50
Enter age:	37
		10.00	28.50
Enter age:	60
		6.00	34.50
Enter age:	0

You pay $34.50.
