Challenge: Array Loops

Loop through the numbers array and if the value of the element is even, add 1 to it, and if it's odd, multiply it by two. The original array should be modified.

cs

main

copy
123456789101112131415161718192021222324252627
using System; namespace ConsoleApp { internal class Program { static void Main(string[] args) { int[] numbers = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }; for(_____) { if(_____) { _____ } else { _____ } } foreach(int i in numbers) { Console.WriteLine(i); } } } }
  1. All the numbers that give a remainder 0 when divided by 2 are called even numbers.
  2. Use the loop variable i to index and access the array elements.

Everything was clear?

How can we improve it?

Thanks for your feedback!
