**Proposed exercise**

**Write a program to calculate (and display) the absolute value of a number x: if the number is positive, its absolute value is exactly the number x; if it is negative, its absolute value is -x.**

Do it in two different ways in the same program: using "if" and using the "conditional operator" (?)

**Output**

**Solution**

using System; public class AbsoluteValue { public static void Main() { Console.Write("Enter a number: "); int n = Convert.ToInt32(Console.ReadLine()); int abs; if( n < 0 ) abs = -n; else abs = n; Console.WriteLine("Absolute valor is {0}", abs); } }
