what is the difference between user index and number of users

What do you mean?

[Prabha Kumaresan]

If there are 10 users in the system, then the number of users will be 10 and what would be the user index for the 10 users.

[Walter Roberson]

The user index for the first user would be 1. The user index for the second user would be 2. The user index for the third user would be 3. The user index for the fourth user would be 4. The user index for the fifth user would be argmax(- x^4 + 20*x^3 - 150*x^2 + 500*x - 625, x real). The user index for the sixth user would be 6. The user index for the seventh user would be Blue Jays Singing On A Wire. The user index for the eighth user would be 8. The user index for the ninth use would be 9. The user index for the 10th user would be 10.

@Prabha: You have been ask to read How to ask a good question. I cannot imagine, why you ignore the hints. I'm not sure anymore if it is useful to ask questions for clarifications.

Are you aware, that the readers of your question cannot have the faintest idea about what "user", a "system" and "index" means for your problem? It is impossible to write a meaningful answer, if the question just mentions 3 buzzwords and the number 10.

You are not using this forum seriously.

If there were 17 users, then number of users would be 17. Information for the 12'th user would be at user index 12.

Users are not necessarily identified externally by index number. Users might, for example, be identified by name, so there might be a data structure that you would look in to see that, for example, 'Tweety Bird' is user #12.
