Exercise:

Absolute value 17


Objetive:

Write a C# 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" (?)


Code:

using System;
public class Exercise41
{
    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);

        abs = n < 0 ? -n : n;

        Console.WriteLine("And also {0}", abs);
    }
}
