Check Total Occurrence Of A Number In An Array In C#

In this blog, we create a c# program which takes input from the user and check in predefine array that how many times that number occurs in that array.

In this blog, we will create a c# program that takes input from the user and check-in predefine array to check how many times that number occurs in that array.

using System;
using System.Linq;
namespace CheckOccurrenceOfNumberInArray
{
    class Program
    {
        static void Main(string[] args)
        {
            int[] array = { 1, 20, 15, 23, 15, 14, 26, 188,175,12, 36, 78, 15, 3, 5, 91, 822, 100, 1202, 78, 95, 12, 123, 12, 14, 25, 36, 15, 36, 95, 45, 10, 20, 30, 04, 50, 40, 60, 70, 80, 90, 104 };
            Console.WriteLine("Your Array...");
            for (int i = 0; i < array.Length; i++)
            {
                Console.Write(array[i] + " ");
            }
            Console.WriteLine("\n\n");
            Console.Write("Enter number to check occurrence  :  ");
            int number = Convert.ToInt32(Console.ReadLine());

            int occurrences = array.Count(x => x == number);
            Console.WriteLine("Occurrence of {0} in given array is {1}", number, occurrences);
            Console.ReadKey();
        }
    }
}

Explanation 

• In this program, first we declare an array of integer types and then print it to show the user.
• Then take input from the user.
• Check that input with our array using the LINQ count method and pass expression in that method also that element is equal to the given number.
