Absolute value

 Friday, April 05, 2013 published by Exercises C#
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);    
}
}
