Array data type, used in a programming language to specify a variable that can be indexed

During my experiment with array / hash variable, i’ve found this interesting website. The wiki explains how to sort the integers in the array by using a variety of languages. even some programming languages that I do not know at all.

I’ll pick a few examples of sorting functions described in the wiki

Sort an integer array using C language:

#include <stdlib.h>  /* qsort() */
#include <stdio.h>   /* printf() */

int intcmp(const void *aa, const void *bb)
	const int *a = aa; *b = bb;
	return (*a < *b) ? -1 : (*a > *b);

int main()
	int nums[5] = {2,4,3,1,2};
	qsort(nums, 5, sizeof(int), intcmp);
	printf("result: %d %d %d %d %d\n",
		nums[0], nums[1], nums[2], nums[3], nums[4]);
	return 0;

Sort an integer array using C++ language:

#include <algorithm>

int main()
	int nums[] = {2,4,3,1,2};
	std::sort(nums, nums+5);
	return 0;

Sort an integer array using C# language:

using System;
using System.Collections.Generic;

public class Program {
	static void Main() {
		int[] unsorted = { 6, 2, 7, 8, 3, 1, 10, 5, 4, 9 };

Sort an integer array using Java language:

import java.util.Arrays;

public class example {
	public static void main(String[] args)
		int[] nums = {2,4,3,1,2};

Sort an integer array using Perl language:

@nums = (2,4,3,1,2);
@sorted = sort {$a <=> $b} @nums;

Sort an integer array using php language:

$nums = array(2,4,3,1,2);

Sort an integer array using python language:

nums = [2,4,3,1,2]

Sort an integer array using bash language:


function mysort {
        for i in ${unsorted_array[@]};
                echo "$i";
        done | sort -n;

unsorted_array=(1 2 4 3 5)
echo "Unsorted array: ${unsorted_array[@]}"

sorted_array=( $(mysort) )
echo "Sorted array: ${sorted_array[@]}"

Happy sorting 🙂
