How do I output only even numbers in C#

I’m stuck on C# 15.2 practice I’ve done this code below which outputs all numbers going from 1 to the number the console input. It says int numbers that can be divided by 2 are even numbers but I don’t know what todo with this information. int num = Convert.ToInt32(Console.ReadLine()); int res = 1; //your code goes here while(++res<=num) Console.WriteLine(res);

If you only want to output even numbers, you can start res at 2 and then just increment res by 2 for each iteration up to num. If you want to check if a number is even (or evenly divisible by 2) you can use the modulo operator and check that the remainder is 0. num % 2 == 0 // true if even false otherwise.
