I am receiving abnormal program termination

A build is able to terminate abnormally during runtime after it is generated from the error-free code. This doesn't seem the case with the posted code.

Look at line 4, how long is the array str?
When you call gets at line 6 how many characters do you type in?

What happens if you only type 1 character?
What if you type more than 1?
What if you type lots?


gets is a dangerous function because it does not limit the number of characters entered, gets is a much better function because it does.
