hello Firoz,
preprocess ur sieve array and store number of primes from 1 to i at index i.

you can do it easily.
let say prime[i] is telling u number primes till index i using this info u can work for index i+1 by doing something as follows.
a) if i+1 is prime then
prime[i+1]=1+prime[i]
b) otherwise
prime[i+1]=prime[i]
