#### Determine if any two integers in array sum to given integer

In this Article we will see any 2 number from the array sum is equal to given targeted number or not.

C# code
 static void Main(string[] args)         { int[] arr = new int[] { 1, 4, 2, 9, 5, 6, 3, 11 };               Console.Write("Enter the Traget Number : ");               int number = int.Parse(Console.ReadLine());               if ( TwoIntegersSumToTarget(arr, number))             Console.WriteLine("Given sum number exist");            else                 Console.WriteLine("Given sum number not exist");               Console.ReadLine();        }               public static bool TwoIntegersSumToTarget(int[] arr, int target)         {             for (int i = 0; i < arr.Length; i++)             {                 for (int k = 0; k < arr.Length; k++)                 {                     if (i != k)                     {                         int sum = arr[i] + arr[k];                         if (sum == target)                             return true;                     }                 }             }             return false;         }
