Write a program for sorting variables of any datatype without the use of std::sort .
Examples:
Input : 2000, 456, -10, 0
Output : -10 0 456 2000
Input : "We do nothing"
"Hi I have something"
"Hello Join something!"
"(Why to do work)"
Output :(Why to do work)
Hello Join something!
Hi I have something
We do nothing
The examples above show, we can have any data type elements present as an input and output will be in a sorted form of the input data. The idea here to solve this problem is to make a template.
Method 1 (Writing our own sort) In below code, we have implemented Bubble Sort to sort the array.
CPP
// CPP program to sort array of any data types.#include <bits/stdc++.h>using namespace std;// Template formed so that sorting of any // type variable is possibletemplate <class T>void sortArray(T a[], int n){ // boolean variable to check that // whether it is sorted or not bool b = true; while (b) { b = false; for (size_t i=0; i<n-1; i++) { // swapping the variable // for sorting order if (a[i] > a[i + 1]) { T temp = a[i]; a[i] = a[i + 1]; a[i + 1] = temp; b = true; } } }}// Template formed so that sorting of any // type variable is possibletemplate <class T>void printArray(T a[], int n){ for (size_t i = 0; i < n; ++i) cout << a[i] << " "; cout << endl;}// Driver codeint main(){ int n = 4; int intArr[n] = { 2000, 456, -10, 0 }; sortArray(intArr, n); printArray(intArr, n); string strArr[n] = { "We do nothing", "Hi I have something", "Hello Join something!", "(Why to do work)" }; sortArray(strArr, n); printArray(strArr, n); float floatArr[n] = { 23.4, 11.4, -9.7, 11.17 }; sortArray(floatArr, n); printArray(floatArr, n); return 0;} |
Java
import java.util.Arrays;class Main { // Generic method for sorting an array of any type public static <T extends Comparable<T>> void sortArray(T[] a) { boolean sorted; do { sorted = true; for (int i = 0; i < a.length - 1; i++) { // Compare adjacent elements and swap them if they are out of order if (a[i].compareTo(a[i + 1]) > 0) { T temp = a[i]; a[i] = a[i + 1]; a[i + 1] = temp; sorted = false; } } } while (!sorted); // Repeat the process until the array is sorted } // Generic method for printing an array of any type public static <T> void printArray(T[] a) { for (T value : a) { // Print each element followed by a space System.out.print(value + " "); } System.out.println(); // Move to the next line after printing the array } public static void main(String[] args) { Integer[] intArr = { 2000, 456, -10, 0 }; sortArray(intArr); // Sort the array of integers printArray(intArr); // Print the sorted integer array String[] strArr = { "We do nothing", "Hi I have something", "Hello Join something!", "(Why to do work)" }; sortArray(strArr); // Sort the array of strings printArray(strArr); // Print the sorted string array Float[] floatArr = { 23.4f, 11.4f, -9.7f, 11.17f }; sortArray(floatArr); // Sort the array of floating-point numbers printArray(floatArr); // Print the sorted float array }} |
Python
def sort_array(a): sorted = False while not sorted: sorted = True for i in range(len(a) - 1): # Compare adjacent elements and swap them if they are out of order if a[i] > a[i + 1]: a[i], a[i + 1] = a[i + 1], a[i] sorted = False# Generic method for printing an array of any typedef print_array(a): for value in a: # Print each element followed by a space print(value), print() # Move to the next line after printing the array# Main functionif __name__ == "__main__": int_arr = [2000, 456, -10, 0] sort_array(int_arr) # Sort the array of integers print_array(int_arr) # Print the sorted integer array str_arr = ["We do nothing", "Hi I have something", "Hello Join something!", "(Why to do work)"] sort_array(str_arr) # Sort the array of strings print_array(str_arr) # Print the sorted string array float_arr = [23.4, 11.4, -9.7, 11.17] sort_array(float_arr) # Sort the array of floating-point numbers print_array(float_arr) # Print the sorted float array |
C#

Output
-10 0 456 2000 (Why to do work) Hello Join something! Hi I have something We do nothing -9.7 11.17 11.4 23.4
Method 2 (Using Library Function) We can use std::sort in C++ to sort array of any data type.
CPP
// CPP program to sort array of any data types.#include <bits/stdc++.h>using namespace std;// Template formed so that sorting of any // type variable is possibletemplate <class T>void printArray(T a[], int n){ for (size_t i = 0; i < n; ++i) cout << a[i] << " "; cout << endl;}// Driver codeint main(){ int n = 4; int intArr[n] = { 2000, 456, -10, 0 }; sort(intArr, intArr + n); printArray(intArr, n); string strArr[n] = { "We do nothing", "Hi I have something", "Hello Join something!", "(Why to do work)" }; sort(strArr, strArr + n); printArray(strArr, n); float floatArr[n] = { 23.4, 11.4, -9.7, 11.17 }; sort(floatArr, floatArr+n); printArray(floatArr, n); return 0;} |
