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" (?)

Solution

using System; public class Exercise044 { public static void Main() { int n, abs; Console.Write("Enter a number: "); n = Convert.ToInt32(Console.ReadLine()); if(n<0) abs = -n; else abs = n; Console.WriteLine("Absolute valor is {0}", abs); //valor = condicion? siCierto;siFalso; abs = n<0 ? -n: n; Console.WriteLine("And also {0}", abs); } }
