Question

I need to write a program that enters from the console a positive integer n and prints all the numbers from 1 to n, on a single line, separated by a space.

Examples:

n	output
3	1 2 3
5	1 2 3 4 5

 

Answer 1

Here is my code - I used for loop:

using System;

class NumbersFromOneToN
{
    static void Main()
    {
        Console.WriteLine("Please write your number: ");
        int n = int.Parse(Console.ReadLine());

        for (int i = 1; i <= n; i++)
        {
            Console.Write("{0} ",i);
        }
        Console.WriteLine();
    }
}

Answer 2

With while loop (instead of for loop):

using System;

class Numbers
{
    static void Main()
    {
        {
            Console.WriteLine("Write a number: ");
            int n = int.Parse(Console.ReadLine());
            int i = 1;

            while (i <= n)
            {
                Console.Write("{0} ",i++);
            }
            Console.WriteLine();
        }
    }
}
