C# Program to Sort an Array
Most of the IT companies check the coding skills and problem-solving skills as well along with the theoretical interview questions. Sometimes you are free to write the pseudo code and sometimes you are asked to write the complete program either on any paper or any editor.
This question is asked in the coding interview to write the program. Here you can find the program as well as a live running program so that you can test the program immediately.
Question:
How can you sort an array without using any array library function? Write a program to sort an array.

using System;
public class Program
{
public static void Main()
{
int[] unsortedArray = new int[8] {5, 1, 6, 2, 7, 3, 8, 4};
Console.WriteLine("UnSorted Array: ");
Console.WriteLine("------------------------------------------ ");
for( int i = 0; i < unsortedArray.Length; i++)
{
Console.WriteLine(unsortedArray[i]);
}
// Sorting using User Defined Function
var sortedArray = SortArray(unsortedArray);
Console.WriteLine("\nSorted Array Without Library Function: ");
Console.WriteLine("------------------------------------------ ");
for( int i = 0; i<= sortedArray.Length - 1; i++)
{
Console.WriteLine(sortedArray[i]);
}
// Sorting using Library Function
Array.Sort(unsortedArray);
Console.WriteLine("\nSorted Array Using Library Function: ");
Console.WriteLine("------------------------------------------ ");
for( int i = 0; i <= unsortedArray.Length - 1; i++)
{
Console.WriteLine(unsortedArray[i]);
}
}
public static int[] SortArray(int[] array)
{
int temp = 0;
for (int i = 0; i < array.Length ; i++)
{
for (int j = i+1; j < array.Length ; j++)
{
if (array[i] > array[j]) {
temp = array[i];
array[i] = array[j];
array[j] = temp;
}
}
}
return array;
}
}
Output:
UnSorted Array: ------------------------------------------ 5 1 6 2 7 3 8 4 Sorted Array Without Library Function: ------------------------------------------ 1 2 3 4 5 6 7 8 Sorted Array Using Library Function: ------------------------------------------ 1 2 3 4 5 6 7 8
