# Absolute value - Tutorial C# Sharp

## Lesson 2:

## Flow Control

## Exercise 2.27:

## Absolute value

## Objetive:

##
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" (?)

## Source Code:

```
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);
abs = n < 0 ? -n : n;
Console.WriteLine("And also {0}", abs);
}
}
```
