N-th Prime Number

Example problem:
What is 6th prime number?
By listing the first six prime numbers: 2, 3, 5, 7, 11, and 13, we can see that the 6-th prime is 13

Now, what is 10001-th prime number?

It is simple, if we use program to count it:

       for(j=2; j<i; j++){
             flag = 0;
          if(counter == n){
             printf("It is %d-th prime number: %d", n, i);
          flag = 1;
    return 0;
