5.4.2: While loop: Print 1 to N. Write a while loop that prints from 1 to user_num, increasing by 1 each time. Sample output with input: 4 1 2 3 4

import java.util.Scanner;

class Main {

 public static void main(String[] args) {

   Scanner in = new Scanner(System.in);

   System.out.println("Enter a number");

   int user_num = in.nextInt();

   int n = 1;

   while(n <= user_num){

     System.out.print(n+" ");

     n++;

   }

 }

}

Explanation:

Written in Python:

i = 1

user_num = int(input()) # Assume positive

while i <= user_num:

   print(i)

   i += 1
