Program:

import java.util.Scanner;

public class Series

{

public static void main(String args[])

{

Scanner sc = new Scanner(System.in);

System.out.print("Enter the number of terms: ");

int n = sc.nextInt();

int s = 0, c;

for (c = 1; c <= n; c++)

{

s = s * 10 + c;

System.out.print(s + " ");

}

}

}

Yes this loop is correct if the user enters 5 the output will be 12345 and if the user enters 8 the output will be 12345678.
