14 14 is an even number True True
using System;
namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
// Take an input from the user.
int a = Convert.ToInt32(Console.ReadLine());
// Call the methods from EvenOrOdd class and user input as first parameter
// and then add the condition using lambda syntax (or you can use function if you'd like to).
// I prefer lambda syntax because it is easier and shorter.
EvenOrOdd.CheckNumber(a, x => x % 2 == 0);
// Or you can simply use Predicate<>
Predicate<int> isEven = even => even % 2 == 0;
Console.WriteLine(isEven(a));
// Or maybe use Func<>
Func<int, bool> IsEven = a => a % 2 == 0;
Console.WriteLine(IsEven(a));
}
}
// Declare the delegate with bool return type and int x as parameter.
delegate bool IsEven(int x);
// Create a class to store the Function. (You don't have to create a class for this).
class EvenOrOdd
{
// This function takes in 2 parameters, first is int x and the delegate.
public static void CheckNumber(int x, IsEven isEven)
{
// This is where the delegate comes to use.
// remember that the delegate takes an int parameter, so we pass x value as an arguments.
// And if it's an even number, it will print the following message.
if(isEven(x))
Console.WriteLine($"{x} is an even number");
// Else, print the following message.
else
Console.WriteLine($"{x} is an odd number");
}
}
/*
As you can see we don't hard code anything. This delegate is very useful to create a reusable class
and easier to maintain. And it looks cool xD
