Here is what i need the PRG to do...

Assignment #4

When you toss a coin, generally, you don't get too many heads or tails in a row, but
if you toss enough times, eventually you will get a number of heads in a row or tails in
a row. It's easy to get 2 or 3 heads or tails in a row, but if you want a larger number
of heads or tails in a row, you'll have to toss more times.
Write a program that reads an integer from the user between 2 and 9.
If the number entered is outside the above range, ask for another until the number
entered is in that range. If n represents the integer entered by the user, keep generating
and displaying 0's and 1's randomly until n 0's in a row have been generated and displayed.
Print how many numbers had to be generated to get that many 0's in a row.

The following is a sample interaction between the user and the program:
How many consecutive 0's would you like to see? [between 2 and 9]: 20
Invalid entry! Enter an integer between 2 and 9, please.
How many consecutive 0's would you like to see? [between 2 and 9]: 4
0010111001010110010010000
It took 26 tries to geet 4 0's in a row.
Press any key to continue.

Create two counters. First counts the rolls. Assuming heads, second gets set to 0 on each tail, incremented by 1 on each head.

When second matches the number entered, first counter is number of rolls it took.
