﻿ C# - New array of the values after the value 5 from a array

# C#: Create a new array taking the elements after the element value 5 from a given array of integers

## C# Sharp Basic Algorithm: Exercise-129 with Solution

Write a C# Sharp program to create an array by taking the elements after element value 5 from a given array of integers.

Visual Presentation:

Sample Solution:

C# Sharp Code:

using System; // Importing the System namespace

namespace exercises // Defining a namespace called 'exercises'
{
class Program // Defining a class named 'Program'
{
static void Main(string[] args) // The entry point of the program
{
// Calling the 'test' method with a given integer array and storing the returned array in 'item'
int[] item = test(new[] { 1, 2, 3, 5, 7, 9, 11 });

// Outputting the elements of the new array formed after the element '5' if found
Console.Write("New array: ");
foreach (var i in item) // Looping through each element in the 'item' array
{
Console.Write(i.ToString() + " "); // Outputting each element followed by a space
}
}

// Method to extract elements of an array after the occurrence of the value '5'
static int[] test(int[] numbers)
{
int len = numbers.Length; // Storing the length of the array
int size = 0; // Variable to store the size of elements after '5'
int[] post_ele_5; // Array to hold elements after '5'

int i = len - 1; // Starting from the last index of the array

// Finding the index of the first occurrence of '5' from the end of the array
while (i >= 0 && numbers[i] != 5)
{
i--;
}
i++; // Incrementing to move to the element after '5'

size = len - i; // Calculating the number of elements after '5'
post_ele_5 = new int[size]; // Creating an array with size determined after '5'

// Storing elements after '5' into the post_ele_5 array
for (int j = 0; j < size; j++)
{
post_ele_5[j] = numbers[i + j];
}

return post_ele_5; // Returning the array containing elements after '5'
}
}
}

Sample Output:

New array: 7 9 11
