C# find biggest number

Question

It's the first time I am using c# so I am not very familiar with it. I would like to create a simple program to find the biggest number if I have the user entering 3 numbers. I just need to know what to put in the code, because I am not very sure.

Answer 1

Use Math.Max :

int x = 3, y = 4, z = 5;
Console.WriteLine(Math.Max(Math.Max(x, y), z));

Answer 2

There is the Linq Max() extension method. It's available for all common number types(int, double, ...). And since it works on any class that implements IEnumerable<T> it works on all common containers such as arrays T[] , List<T> ,...

To use it you need to have using System.Linq in the beginning of your C# file, and need to reference the System.Core assembly. Both are done by default on new projects(C# 3 or later)

int[] numbers=new int[]{1,3,2};
int maximumNumber=numbers.Max();

You can also use Math.Max(a,b) which works only on two numbers. Or write a method yourself. That's not hard either.

Answer 3

You can use the Math.Max method to return the maximum of two numbers, eg for int :

int maximum = Math.Max(number1, Math.Max(number2, number3))

There ist also the Max() method from LINQ which you can use on any IEnumerable .

Answer 4

using System;
using System.Linq;

class Program
{
    static void Main(string[] args)
    {
        int[] numbers = { 3, 9, 5 };
        int biggestNumber = numbers.Max();
        Console.WriteLine(biggestNumber);
        Console.ReadLine();
    }
}

Answer 5

I needed to find a way to do this too, using numbers from different places and not in a collection. I was sure there was a method to do this in c#...though by the looks of it I'm muddling my languages...

Anyway, I ended up writing a couple of generic methods to do it...

    static T Max<T>(params T[] numberItems)
    {
        return numberItems.Max();
    }

    static T Min<T>(params T[] numberItems)
    {
        return numberItems.Min();
    }

...call them this way...

    int intTest = Max(1, 2, 3, 4);
    float floatTest = Min(0f, 255.3f, 12f, -1.2f);

Answer 6

If your numbers are a, b and c then:

    int a = 1;
    int b = 2;
    int c = 3;

    int d =  a > b ? a : b;
    return c > d ? c : d;

This could turn into one of those "how many different ways can we do this" type questions!

Answer 7

Here is the simple logic to find Biggest/Largest Number

Input : 11, 33, 1111, 4, 0 Output : 1111

namespace PurushLogics
{
    class Purush_BiggestNumber
    {
        static void Main()
        {
            int count = 0;
            Console.WriteLine("Enter Total Number of Integers\n");
            count = int.Parse(Console.ReadLine());

            int[] numbers = new int[count];

            Console.WriteLine("Enter the numbers"); // Input 44, 55, 111, 2 Output = "111"
            for (int temp = 0; temp < count; temp++)
            {
                numbers[temp] = int.Parse(Console.ReadLine());
            }

            int largest = numbers[0];
            for (int big = 1; big < numbers.Length; big++)
            {
                if (largest < numbers[big])
                {
                    largest = numbers[big];
                }
            }
            Console.WriteLine(largest);
            Console.ReadKey();
        }
    }
}
