How to Add Spaces to for Loop Output in JavaScript

for (var i = -52; i <= 1066; i++) {       document.write(i+" ");}

Adding spaces in front the string in a for loop

You're on the right track. There are three steps that you need to do here. You need to create a cross like this (assuming number is 13):

   *
   *
   *
*******
   *
   *
   *

You need to create Math.floor(13/4) (comes out to 3) rows of a single star, with each star after Math.floor(13/4) spaces. Then you need a row of Math.ceil(13/2) stars starting at position 0. Lastly, you need the same number of stars as you did before that row, so you can just do the same thing again.

Using your code, I would do something like this:

let num = prompt("Enter an odd number");

while (num%2 == 0) {
    console.log("User did not enter an odd number");
    num = prompt("Enter an odd number");
}
console.log("User's number is " +num);

let star = " ";
let pos = Math.floor(num/4);
let vertical = star.repeat(pos) + "*";

for (var i = 0; i < pos; i++) {
    console.log(vertical);
}

console.log("*".repeat(Math.ceil(num/2)));

for (var i = 0; i < pos; i++) {
    console.log(vertical);
}

Add spaces to string with loop

The thing you want is to print a number of spaces that is equivalent to the current line number - 1. So you'll have to create a for loop for that.

import java.util.*;

public class Pattern
{

    public static void main(String[] args)
    {

        int input;
        Scanner kb = new Scanner(System.in);    

        System.out.print("Enter a positive number: ");
        input = kb.nextInt();

        while (input <= 0)
        {
            System.out.print("That isn't positive, try again: ");
            input= kb.nextInt();
        }

        for (int number = 0; number < input; number++)
        {
            System.out.print("#");

            //print spaces equal to the number variable
            for(int count = 0; count < number; count++)
            {
                System.out.print(" ");
            }

            System.out.println("#");
        }               

    }

}

For loop print in single line separated by spaces - JS

Concatenate with a string in the loop instead, then console.log that string:

let n = 10;let str = '';for (let i = 1; i <= n; i++) {  str += i + ' ';}console.log(str.trim());
