Distinguish between a database lockout and a deadlock.
What will be an ideal response?
To achieve data currency, simultaneous access to individual data elements or records by multiple users needs to be prevented. The solution to this problem is a database lockout, which is a software control that prevents multiple simultaneous accesses to data. A deadlock occurs when multiple users seeking access to the same set of records lockout each other. As a result, the transactions of all users assume a wait state until the locks are removed. A deadlock is a permanent condition that must be resolved by special software that analyzes each deadlock condition to determine the best solution.

Modify example program so it can accommodate any positive data value up to the maximum that the computer can accept. Your solution should not depend upon knowing the value of that maximum number.
