I know how to create threads but I need to create threads based on user input, i.e., if you mention 5 then 5 threads have to be generated. each thread has different tasks to do.

So use a loop.

each thread has different tasks to do.


Then you must have some logic for deciding which task to assign to each thread. Nobody here can tell you how to do that, since it depends on your requirements, which you haven't specified.

each thread generated will independently generate a random integer as an upper limit, and then computes and prints the no. of primes less than or equal to that upper limit .

simple program to create thread:

from some input source.


Also ... Since most, if not all of this problem is not thread related, it may be best to implement and test the components without threads first. So, do you have code that generates a random number? that gets input from a user? that generate prime numbers?

@Henry Wong : Nicely put...

@Mohan Mehra : as Henry rightly put, address it step by step basis. Not to be rude but a word of advice: These forums are here to help you understand things and code better. That means a fair amount of home work by original poster is expected. Bottom line - please do not expect people to code it for you.
