Directions:

   Do all of the following problems using loops. Do not
use arrays, matrix, colon, or linspace. Although it is
possible to do all of these problems without loops, do not
do so. The idea of this lab is to practice using loops.

Problems:

1. Write a program called lab6_1.m that prints every
   integer between 1 and 10, inclusive.

2. Write a program called lab6_2.m that prints the even 
   numbers between 1 and a user-input number.

3. Write a program called lab6_3.m that finds the average
   of all numbers input by the user. 

For problem 3, ask for user-input number one at a time. 
When the user input 0, that signifies the end of input.
Do not include the last 0 in your calculation of average.

Example:

Enter a number (0=finish): 4
Enter a number (0=finish): 1
Enter a number (0=finish): -5
Enter a number (0=finish): 10
Enter a number (0=finish): 0

The average is 2.5
